• Reversing an lvreduce of LVM to original size

  - by praspa

  On a RHEL system that uses LVM 2 with 4K blocks. Have been successful in reducing the LV, but trying to get steps to reverse the operation so that the LV returns to its original size. Using these steps to reduce the LV by 1GB, # umount /foo # e2fsk -f /dev/mylvm/foo # resize2fs /dev/mylvm/foo <Current LV Block count - 1GB/4K> # lvreduce --size <Current # GB - 1GB> /dev/mylvm/foo Then to reverse the reduction # lvextend --size <Original #GB> /dev/mylvm/foo # resize2fs /dev/mylvm/foo The reversal gets close to the orignal size. A 'df -h' reports that it seems to be about ~ 0.1GB shy of the original size. Using these utilities, is there a better procedure to shrink and grow the LV so that the original state can be recovered effectively?

• Error: You need to load the kernel first in Grub

  - by Exeleration-G

  I have Lubuntu 11.10 installed on /dev/sda3, and Xubuntu 11.10 on /dev/sda5. A while ago, while being on Lubuntu, I made a mistake somewhere in creating a Live USB: by mistake, I installed a Live USB bootloader into /dev/sda3. This didn't result in any problem at that time. Today, I updated the kernel. I had to restart Lubuntu. In Grub, Lubuntu suddenly didn't appear anymore, and I booted automatically in Xubuntu. I tried to run update-grub and tried to use grub-customizer to get Lubuntu back in Grub, but this didn't work. I ran os-prober, but it doesn't show me Lubuntu. Then, I tried to add a new entry to /etc/grub.d/ on /dev/sda5 called 12_lubuntu. It contained the following: #!/bin/sh -e echo "Lubuntu" cat << EOF menuentry "Lubuntu" { set root=(hd0,3) linux /boot/vmlinuz initrd /boot/initrd.img } EOF After doing that, I ran update-grub and with grub-customizer, I wrote the Grub-configuration to MBR, that is: /dev/sda. Suddenly, Lubuntu appeared in Grub. I tried to launch it, but when doing this, the following message appeared: Error: You need to load the kernel first How can I make Grub start Lubuntu again?

• Encrypting a non-linux partition with LUKS.

  - by linuxn00b

  I have a non-Linux partition I want to encrypt with LUKS. The goal is to be able to store it by itself on a device without Linux and access it from the device when needed with an Ubuntu Live CD. I know LUKS can't encrypt partitions in place, so I created another, unformatted partition of the EXACT same size (using GParted's "Round to MiB" option) and ran this command: sudo cryptsetup luksFormat /dev/xxx Where xxx is the partition's device name. Then I typed in my new passphrase and confirmed it. Oddly, the command exited immediately after, so I guess it doesn't encrypt the entire partition right away? Anyway, then I ran this command: sudo cryptsetup luksOpen /dev/xxx xxx Then I tried copying the contents of the existing partition (call it yyy) to the encrypted one like this: sudo dd if=/dev/yyy of=/dev/mapper/xxx bs=1MB and it ran for a while, but exited with this: dd: writing `/dev/mapper/xxx': No space left on device just before writing the last MB. I take this to mean the contents of yyy was truncated when it was copied to xxx, because I have dd'd it before, and whenever I have dd'd to a partition of the exact same size, I never get that error. (and fdisk reports they are the same size in blocks). After a little Googling I discovered all luksFormat'ted partitions have a custom header followed by the encrypted contents. So it appears I need to create a partition exactly the size of the old one + however many bytes a LUKS header is. What size should the destination partition be, no. 1, and no. 2, am I even on the right track here? UPDATE I found this in the LUKS FAQ: I think this is overly complicated. Is there an alternative? Yes, you can use plain dm-crypt. It does not allow multiple passphrases, but on the plus side, it has zero on disk description and if you overwrite some part of a plain dm-crypt partition, exactly the overwritten parts are lost (rounded up to sector borders). So perhaps I shouldn't be using LUKS at all?

• Taking Your Business Scorecard Golfing

  - by tobyehatch

  Our workplace world is definitely changing. Not only are we taking work home, but we are working during odd hours in some very strange places.  I had the pleasure of interviewing Jacques Vigeant, Product Strategy Manager for Oracle Business Intelligence and Enterprise Performance Management, on a Podcast, and he enlightened me about how our mobile devices and business scorecards are enabling us to be more accountable and keep a watchful eye on business – even while on the golf course.Business scorecards have been around for many years - so I asked Jacques if he felt they had changed significantly due to technology. His answer was, “Yes, and no.”  Jacques agreed that scorecard enthusiasts are still passionate about executing the company strategy and monitoring Key Performance Indicators (KPIs), but scorecards and Business Intelligence (BI) as a whole have changed.  He explained that five to six years ago, people did BI work at the office and, for the most part, disconnected from their computer and workplace when they went home – with the exception of checking email and making a phone call or two. But now, that is no longer the case. People are virtually always connected with work and, more importantly, expect their BI and scorecards to be ‘always on,’ regardless of whether they are at their desk or somewhere else.Basically, the BI paradigm has changed from a 'pull' model, where employees are at their desks querying or pulling information from the system, to a 'push' model where employees expect their BI and scorecard systems to reach out (or push information) to them when there is something of note to learn or something on which they need to take action. I found this very interesting. However mobile devices do have their limitations with respect to screen sizes – does it really make sense to look at your strategy/scorecard on tiny devices? What kind of scorecard activities can you really expect to be able to do? Jacques’ answer was very logical. “When you think of a scorecard, it is really comprised of an organization of KPIs that are aligned with the strategic objectives of your company. KPIs are the heart of how you will execute your strategy. So, if you decompose that a little more, each KPI is well defined with the thresholds that you should keep an eye on and who is responsible for them. When we talk about scorecarding on a phone, we aren’t talking about surfing the strategy and exploring the strategy map like we do on the desktop. In a scorecarding context, we use the phone more as an alerting mechanism or simple monitoring device for your KPIs.”Jacques gave a great example of an inventory manager who took part of an afternoon off to go golfing before winter finally hit, and while on the front nine holes, his phone vibrated. His scorecard was alerting him that the inventory levels for one of the products was below some threshold that he had set.  From his phone, he had set up three options within Oracle Scorecard and Strategy Management (OSSM) for this type of situation:  1. Contact the warehouse manager directly by phone and work it out (standard phone function)  2. Tap/hold the KPI and add an annotation to the KPI in OSSM using the dictation capabilities of the phone and deal with it more fully when he gets back to the office  3. Tap/hold the KPI and invoke a business process from OSSM to transfer product from another warehouse with higher stock levels to the one that needs it  Being on a phone should still give you options to quickly deal with situations as needed, but mobile phones are not designed for nor should try to replicate the full desktop experience. We covered other interesting subjects in the interview, including how Oracle is keeping pace with mobile innovation and new devices such as Google Glasses, Galaxy Gear, Pebble Watches and more, and how Oracle is handling mobile security– which is great news for our mobile workforce.

• Burned CD-R are not identical to the input iso image, why?

  - by Grumbel

  I have the issue that sometimes when I burn an iso image to a CD-R with: sudo wodim -v driveropts=burnfree -data dev=/dev/scd0 input.iso And then read it back out again with: sudo dd if=/dev/cdrom of=output.iso dd: reading `/dev/cdrom': Input/output error ... That I end up with two iso images that are not identical, namely the output.iso is missing 2048 bytes at the end. When I however mount the iso image or CD-R and compare the actual files on the mountpoint, both are identical. Is that expected behavior or is that an actually incorrect burn of the data? And if its expected, how can I verify that the burn process was successful? The reason why I ask in the first place is that it seems to be reproducible behavior, certain iso images come out 2048 bytes short, even on repeated burns, but all burned CD-Rs are under themselves identical. Also what is the reason behind the: dd: reading `/dev/cdrom': Input/output error As it happens always, I assume it is normal, but what is the technical reason behind it? I assume CDs don't allow the device to detect the size directly, so dd reads till it encounters the end the hard way. Edit: User karol on superusers.com mentioned that both the size issue and the read error are the result of using -tao (default) in wodim instead of -dao mode. I couldn't yet test it, but it sounds like the most plausible explanation so far.

• The Mystery of the Vanishing Disk Space

  - by Oddthinking

  My disk space is dwindling by about 2GB a day! I only have a few more days before I run out of space. $ df -h Filesystem Size Used Avail Use% Mounted on /dev/sda4 143G 126G 11G 93% / udev 491M 4.0K 491M 1% /dev tmpfs 200M 696K 199M 1% /run none 5.0M 0 5.0M 0% /run/lock none 499M 144K 499M 1% /run/shm /dev/sda2 1.9G 580M 1.2G 33% /tmp /dev/sda1 92M 29M 58M 33% /boot I have been searching for the biggest directories/log files, deleting and compressing. But I am still losing the war. Finally, I realised I have a big misunderstanding: julian@server1:~$ sudo du -h / | tail -n 1 16G / All of my files in / only add up to 16 GB. That leaves 110 GB unaccounted for! Clearly I have a misunderstanding: I thought the '/dev/sda4' line represented all the files visible from '/'. What should I be reading to understand where the other storage has gone? More details: I have an Ubuntu 11.10 server, that was set-up by data-center staff. It is running my own code (which is fairly prolific with log files, but otherwise doesn't store much stuff on the drive) duplicity for backups (which tends to store a lot of signature files) various other standard services, like Apache, nagios, etc. They are very lightly used. It has been up for about 4 months without a reboot. I lied about the du output (simplified it for effect). It also complained about not being able to access GVFS and the du processes's own resources. I believe they are irrelevant: . du: cannot access `/home/julian/.gvfs': Permission denied du: cannot access `/proc/10841/task/10841/fd/4': No such file or directory du: cannot access `/proc/10841/task/10841/fdinfo/4': No such file or directory du: cannot access `/proc/10841/fd/4': No such file or directory du: cannot access `/proc/10841/fdinfo/4': No such file or directory

But if I do app_dev.php/_profiler/5080653d965eb I get a 404 and the request never gets sent to FPM. How can I alter my ProxyPassMatch to pass anything with .php in the URL? I'm trying to do this with Symfony, but I'm pretty sure it applies to everything.

• Seizing the Moment with Mobility

  - by Kathryn Perry

  A guest post by Hernan Capdevila, Vice President, Oracle Fusion Apps Mobile devices are forcing a paradigm shift in the workplace – they’re changing the way businesses can do business and the type of cultures they can nurture. As our customers talk about their mobile needs, we hear them saying they want instant-on access to enterprise data so workers can be more effective at their jobs anywhere, anytime. They also are interested in being more cost effective from an IT point of view. The mobile revolution – with the idea of BYOD (bring your own device) – has added an interesting dynamic because previously IT was driving the employee device strategy and ecosystem. That's been turned on its head with the consumerization of IT. Now employees are figuring out how to use their personal devices for work purposes and IT has to figure out how to adapt. Blurring the Lines between Work and Personal Life My vision of where businesses will be five years from now is that our work lives and personal lives will be more interwoven together. In turn, enterprises will have to determine how to make employees’ work lives fit more into the fabric of their personal lives. And personal devices like smartphones are going to drive significant business value because they let us accomplish things very incrementally. I can be sitting on a train or in a taxi and be productive. At the end of any meeting, I can capture ideas and tasks or follow up with people in real time. Mobile devices enable this notion of seizing the moment – capitalizing on opportunities that might otherwise have slipped away because we're not connected. For the industry shapers out there, this is game changing. The lean and agile workforce is definitely the future. This notion of the board sitting down with the executive team to lay out strategic objectives for a three- to five-year plan, bringing in HR to determine how they're going to staff the strategic activities, kicking off the execution, and then revisiting the plan in three to five years to create another three- to five-year plan is yesterday's model. Businesses that continue to approach innovating in that way are in the dinosaur age. Today it's about incremental planning and incremental execution, which requires a lot of cohesion and synthesis within the workforce. There needs to be this interweaving notion within the workforce about how ideas cascade down, how people engage, how they stay connected, and how insights are shared. How to Survive and Thrive in Today’s Marketplace The notion of Facebook isn’t new. We lived it pre-Internet days with America Online and Prodigy – Facebook is just the renaissance of these services in a more viral and pervasive way. And given the trajectory of the consumerization of IT with people bringing their personal tooling to work, the enterprise has no option but to adapt. The sooner that businesses realize this from a top-down point of view the sooner that they will be able to really drive significant innovation and adapt to the marketplace. There are a small number of companies right now (I think it's closer to 20% rather than 80%, but the number is expanding) that are able to really innovate in this incremental marketplace. So from a competitive point of view, there's no choice but to be social and stay connected. By far the majority of users on Facebook and LinkedIn are mobile users – people on iPhones, smartphones, Android phones, and tablets. It's not the couch people, right? It's the on-the-go people – those people at the coffee shops. Usually when you're sitting at your desk on a big desktop computer, typically you have better things to do than to be on Facebook. This is a topic I'm extremely passionate about because I think mobile devices are game changing. Mobility delivers significant value to businesses – it also brings dramatic simplification from a functional point of view and transforms our work life experience.

Installing boot on /dev/sdb. But, somehow i think the grub is either corrupted or removed because i am unable to boot the laptop to any OS now. I get the following message: "no such device" xxxxx followed by huge HEX number GRUB rescue when i type ls on Grub rescue prompt, i can see hd0 & hd1, but thats about it. i tried Boot-repair but it is unable to fix the problem. The following log is generated via boot-repair create log: Boot-repair log I am unable to boot into windows or linux at the moment and need help to fix the grub so i can boot !!

• Oracle Social Network Developer Challenge: Fishbowl Solutions

  - by Kellsey Ruppel

  Originally posted by Jake Kuramoto on The Apps Lab blog. Today, I give you the final entry in the Oracle Social Network Developer Challenge, held last week during OpenWorld. This one comes from Friend of the ‘Lab and Fishbowl Solutions (@fishbowle20) hacker, John Sim (@jrsim_uix), whom you might remember from his XBox Kinect demo at COLLABORATE 12 (presentation slides and abstract) hacks and other exploits with WebCenter. We put this challenge together specifically for developers like John, who like to experiment with new tools and push the envelope of what’s possible and build cool things, and as you can see from his entry John did just that, mashing together Google Maps and Oracle Social Network into a mobile app built with PhoneGap that uses the device’s camera and GPS to keep teams on the move in touch. He calls it a Mobile GeoTagging Solution, but I think Avengers Assemble! would have equally descriptive, given that was obviously his inspiration. Here’s his description of the mobile app: My proposed solution was to design and simplify GeoLocation mapping, and automate updates for users and teams on the move; who don’t have access to a laptop or want to take their ipads out – but allow them to make quick updates to OSN and upload photos taken from their mobile device – there and then. As part of this; the plan was to include a rules engine that could be configured by the user to allow the device to automatically update and post messages when they arrived at a set location(s). Inspiration for this came from on{x} – automate your life. Unfortunately, John didn’t make it to the conference to show off his hard work in person, but luckily, he had a colleague from Fishbowl and a video to showcase his work.    Here are some shots of John’s mobile app for your viewing pleasure: John’s thinking is sound. Geolocation is usually relegated to consumer use cases, thanks to services like foursquare, but distributed teams working on projects out in the world definitely need a way to stay in contact. Consider a construction job. Different contractors all converge on a single location, and time is money. Rather than calling or texting each other and risking a distracted driving accident, an app like John’s allows everyone on the job to see exactly where the other contractors are. Using his GPS rules, they could easily be notified about how close each is to the site, definitely useful when you have a flooring contractor sitting idle, waiting for an electrician to finish the wiring. The best part is that the project manager or general contractor could stay updated on all the action (or inaction) using Oracle Social Network, either sitting at a desk using the browser app or desktop client or on the go, using one of the native mobile apps built for Oracle Social Network. I can see this being used by insurance adjusters too, and really any team that, erm, assembles at a given spot. Of course, it’s also useful for meeting at the pub after the day’s work is done. Beyond people, this solution could also be implemented for physical objects that are in route to a destination. Say you’re a customer waiting on rail shipment or a package delivery. You could track your valuable’s whereabouts easily as they report their progress via checkins. If they deviated from the GPS rules, you’d be notified. You might even be able to get a picture into Oracle Social Network with some light hacking. Thanks to John and his colleagues at Fishbowl for participating in our challenge. We hope everyone had a good experience. Make sure to check out John’s blog post on his work and the experience using Oracle Social Network.

• How to add a new entry to fstab?

  - by Roei

  I mount a device mount /dev/xvdf /mnt/mongo and verify the mount using df-h: Filesystem Size Used Avail Use% Mounted on /dev/xvda1 7.9G 955M 6.9G 12% / tmpfs 299M 44K 299M 1% /dev/shm /dev/xvdf 20G 589M 19G 4% /mnt/mongo But now I'm trying to figure out how to make it auto mount on boot. I understand I need to add a new entry to /etc/fstab, so I perform: $ sed -i '$ a\/dev/xvdf /mnt/mongo xfs defaults 1 1' /etc/fstab But, after reboot, it seems that the auto mount didn't work. The device didn't appear in the df -h list. Should I not use the sed to add the entry? Is the entry I entered incorrect?

• ntfsresize volume and size information

  - by antonio

  I am going to resize my sda2 NTFS partition. When gathering info with ntfsresize, I get: ntfsresize --info /dev/sda2 ntfsresize v2013.1.13 (libntfs-3g) Device name : /dev/sda2 NTFS volume version: 3.1 Cluster size : 4096 bytes Current volume size: 21999993344 bytes (22000 MB) Current device size: 23622320128 bytes (23623 MB) Checking filesystem consistency ... Accounting clusters ... Space in use : 10673 MB (48.5%) Collecting resizing constraints ... You might resize at 10672590848 bytes or 10673 MB (freeing 11327 MB). Please make a test run using both the -n and -s options before real resizing! Can you tell me what is the difference between volume and device size? As for device size, 23622320128 bytes / 1000^2 = 23622.3 MB. Why is 23623 MB reported instead of 23622?

  - by Mustafa Erdinç

  I need to tweak my Dell XPS 13z SSD for maximum performance and life cycle than I read the solutions explained here, but it is for 11.10 and my fstab is different. For now my fstab is looks like this: proc /proc proc nodev,noexec,nosuid 0 0 # / was on /dev/sda1 during installation UUID=abf5ce9e-bdb7-4b2f-a7bd-bbd9efa72a98 / ext4 errors=remount-ro 0 1 # /home was on /dev/sda2 during installation UUID=491427b2-7482-4483-b6eb-7c564b991aff /home ext4 defaults 0 2 # swap was on /dev/sda3 during installation #UUID=7551000d-e708-4e0f-9fd2-9f93119f63fb none swap sw 0 0 /dev/mapper/cryptswap1 none swap sw 0 0 tmpfs /tmp tmpfs mode=1777 And my rc.local is looks like this: echo noop > /sys/block/sda/queue/scheduler echo deadline > /sys/block/sda/queue/scheduler echo 1 > /sys/block/sda/queue/iosched/fifo_batch exit 0 Do you have any suggestions, what should I do?

• Where did my free space go?

  - by Ari B. Friedman

  I have a storage drive (2TB) and an OS drive (90GB SSD). I've run out of space on the OS drive: /$ df -h Filesystem Size Used Avail Use% Mounted on /dev/sdb1 72G 72G 0 100% / udev 5.9G 12K 5.9G 1% /dev tmpfs 2.4G 1.2M 2.4G 1% /run none 5.0M 0 5.0M 0% /run/lock none 5.9G 428K 5.9G 1% /run/shm /dev/sda1 1.9T 639G 1.2T 37% /media/StorageDrive So be it. But when I attempt to figure out where the space has gone, I cannot find it anything remotely approaching the capacity of the drive: /$ sudo du -h -d 1 du: cannot access `./media/StorageDrive/home/ari/.gvfs': Permission denied 675G ./media 2.3G ./var 0 ./proc 7.0M ./tmp 27M ./boot 4.0K ./lib64 12K ./dev 44M ./home 16K ./lost+found 8.0M ./sbin 223M ./lib 4.0K ./selinux 1.4M ./run 140K ./root 8.8M ./bin 4.0K ./mnt 38M ./etc 8.0K ./srv 4.8G ./usr 65M ./opt 0 ./sys 682G . Note the difference between the total (682G) and the mounted drives in /media (675G) is only about 9G. How are 72G being used? Where is this dark matter hiding?

• Create a Remote Git Repository from an Existing XCode Repository

  - by codeWithoutFear

  Introduction Distributed version control systems (VCS’s), like Git, provide a rich set of features for managing source code.  Many development tools, including XCode, provide built-in support for various VCS’s.  These tools provide simple configuration with limited customization to get you up and running quickly while still providing the safety net of basic version control. I hate losing (and re-doing) work.  I have OCD when it comes to saving and versioning source code.  Save early, save often, and commit to the VCS often.  I also hate merging code.  Smaller and more frequent commits enable me to minimize merge time and effort as well. The work flow I prefer even for personal exploratory projects is: Make small local changes to the codebase to create an incrementally improved (and working) system. Commit these changes to the local repository.  Local repositories are quick to access, function even while offline, and provides the confidence to continue making bold changes to the system.  After all, I can easily recover to a recent working state. Repeat 1 & 2 until the codebase contains “significant” functionality and I have connectivity to the remote repository. Push the accumulated changes to the remote repository.  The smaller the change set, the less likely extensive merging will be required.  Smaller is better, IMHO. The remote repository typically has a greater degree of fault tolerance and active management dedicated to it.  This can be as simple as a network share that is backed up nightly or as complex as dedicated hardware with specialized server-side processing and significant administrative monitoring. XCode’s out-of-the-box Git integration enables steps 1 and 2 above.  Time Machine backups of the local repository add an additional degree of fault tolerance, but do not support collaboration or take advantage of managed infrastructure such as on-premises or cloud-based storage. Creating a Remote Repository These are the steps I use to enable the full workflow identified above.  For simplicity the “remote” repository is created on the local file system.  This location could easily be on a mounted network volume. Create a Test Project My project is called HelloGit and is located at /Users/Don/Dev/HelloGit.  Be sure to commit all outstanding changes.  XCode always leaves a single changed file for me after the project is created and the initial commit is submitted. Clone the Local Repository We want to clone the XCode-created Git repository to the location where the remote repository will reside.  In this case it will be /Users/Don/Dev/RemoteHelloGit. Open the Terminal application. Clone the local repository to the remote repository location: git clone /Users/Don/Dev/HelloGit /Users/Don/Dev/RemoteHelloGit Convert the Remote Repository to a Bare Repository The remote repository only needs to contain the Git database.  It does not need a checked out branch or local files. Go to the remote repository folder: cd /Users/Don/Dev/RemoteHelloGit Indicate the repository is “bare”: git config --bool core.bare true Remove files, leaving the .git folder: rm -R * Remove the “origin” remote: git remote rm origin Configure the Local Repository The local repository should reference the remote repository.  The remote name “origin” is used by convention to indicate the originating repository.  This is set automatically when a repository is cloned.  We will use the “origin” name here to reflect that relationship. Go to the local repository folder: cd /Users/Don/Dev/HelloGit Add the remote: git remote add origin /Users/Don/Dev/RemoteHelloGit Test Connectivity Any changes made to the local Git repository can be pushed to the remote repository subject to the merging rules Git enforces. Create a new local file: date > date.txt /li> Add the new file to the local index: git add date.txt Commit the change to the local repository: git commit -m "New file: date.txt" Push the change to the remote repository: git push origin master Now you can save, commit, and push/pull to your OCD hearts’ content! Code without fear! --Don

• Adding git branch to bash prompt on snow leopard

  - by crayment

  I am using this: $(__git_ps1 '(%s)') It works however it does not update when I change directories or checkout a new branch. I also have this alias: alias reload='. ~/.bash_profile' Sample run: user@machine:~/dev/rails$cd git_folder/ user@machine:~/dev/rails/git_folder$reload user@machine:~/dev/rails/git_folder(test)$git checkout master Switched to branch 'master' user@machine:~/dev/rails/git_folder(test)$reload user@machine:~/dev/rails/git_folder(master)$ As you can see it is being set correctly but only if I reload bash_profile. I have wasted way to much time on this. I am using bash on snow leopard. Please help!

• how can I fix error: hd0 out of disk?

  - by rux

  I am running Ubuntu 12.04 on a netbook - Acer AS 1410. After a download session, I restarted the computer and it said: error: hd0 out of disk. Press any key to continue... I pressed everything, but it's just frozen there. Any idea what's wrong with it and what I can do to fix it? I haven't been able to run my computer at all since it's frozen like that. Help please! I booted the live cd and ran sudo fdisk -lu into terminal, and here's what it gave me: Disk /dev/sda: 60.0 GB, 60022480896 bytes 255 heads, 63 sectors/track, 7297 cylinders, total 117231408 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x9a696263 Device Boot Start End Blocks Id System /dev/sda3 2048 117229567 58613760 5 Extended /dev/sda5 * 71647232 109039615 18696192 83 Linux /dev/sda6 109041664 117229567 4093952 82 Linux swap / Solaris /dev/sda7 4096 71645183 35820544 83 Linux Partition table entries are not in disk order I am somewhat of a beginner in this, so don't know what this means. any ideas? Thanks!

• Unmounted disk still spins up regularly

  - by Erik Johansson

  I just added a disk, with partitions but none of them are mounted. The disk will still spin up every now and then. it goes like this: ### disk spins up hdparm -Y /dev/sdb;date /dev/sdb: issuing sleep command 9 feb 2011 23.37.08 CET ### disk spins up hdparm -Y /dev/sdb;date /dev/sdb: issuing sleep command 9 feb 2011 23.46.12 CET Also it always spins up when I shut down the computer. Any tips are welcome, e.g. how can I figure out which process is accessing the disk, are there any daemons doing this? I know it isn't a cron job.
