  • Improving mdadm RAID-6 write speed

    - by BarsMonster
    Hi! I have a mdadm RAID-6 in my home server of 5x1Tb WD Green HDDs. Read speed is more than enough - 268 Mb/s in dd. But write speed is just 37.1 Mb/s. (Both tested via dd on 48Gb file, RAM size is 1Gb, block size used in testing is 8kb) Could you please suggest why write speed is so low and is there any ways to improve it? CPU usage during writing is just 25% (i.e. half of 1 core of Opteron 165) No business critical data there & server is UPS-backed. mdstat is: Personalities : [raid6] [raid5] [raid4] md0 : active raid6 sda1[0] sdd1[4] sde1[3] sdf1[2] sdb1[1] 2929683456 blocks super 1.2 level 6, 1024k chunk, algorithm 2 [5/5] [UUUUU] bitmap: 0/8 pages [0KB], 65536KB chunk unused devices: <none> Any suggestions?

  • How do I configure hardware raid in a Poweredge 2850?

    - by Eric Fossum
    I just bought a Dell Poweredge 2850 from Craigslist and for the most part I'm happy with it's $300 price-tag, but I cannot figure out where to configure the embedded hardware raid... I've seen online you should hit <CTRL-M>, but while booting my box never says that. I have <CTRL-A> (I think) for an LSI Logic config, but that seems to just program SCSI and verify drives on my SCSI-A and SCSI-B. Anyone have a clue where this RAID config is?

  • RAID setup for maximizing data retention and read speed

    - by cat pants
    My goals are simple: maximize data retention safety, and maximize read speeds. My first instinct is to do a a three drive software RAID 1. I have only used fakeraid RAID 1 in the past and it was terrible (would have led to data loss actually if it weren't for backups) Would you say software raid 1 or a cheap actual hardware raid card? OS will be linux. Could I start with a two drive raid 1 and add a third drive on the fly? Can I hot swap? Can I pull one of the drives and throw it into a new machine and be able to read all the data? I do not want a situation where I have a raid card fail and have to try and find the same chipset in order to read my data (which i am assuming can happen) Please clarify any points on which it sounds like I have no idea what I am talking about, as I am admittedly inexperienced here. (My hardest lesson was fakeraid lol) Thanks!

  • How to expand Raid 5 on ICH10 - Gigabyte ex58-ds4?

    - by NeverEatAlone
    I was wondering if there is a relatively simple way to expand my HD space. My setup is 4 x 640 GB drives. Motherboard has 4 ports on 1 controller and 2 ports on another controller, however they cant be joined. I would like to somehow get more store space in raid configuration. One scenario that I can see working is replacing one 640 drive for a 2TB drive. Waiting for Raid to rebuild. Rinse and repeat. However, I have no idea if I would be able to even see/access the new space. All alternatives / ideas are welcome. Thank you

  • Which motherboard for Intel i7 and how to get RAID working?

    - by jasondavis
    I am wanting to build a new PC, I have a couple questions. 1) I am wanting to go with the Intel Core i7 920 Processor, can anyone reccomend a good reliable motherboard for this processor? Graphics card support does not matter (sli-crossfire). I would like to support a lot of ram, so the more ram slots the better. I have read so many bad reviews about certain boards not working good, I would love recommendation from experience. 2) I am wanting to run a couple SSD drives in RAID-0, I have never done this, will I need to purchase anything additional to the MB and CPU and drives to get raid working?

  • Local, Multiple-Blog (ie Dashboard) Blogging Software as Alternative to Blogger [closed]

    - by Synetech inc.
    FOR RE-OPENING: I don’t see how it is “too localized”. Plenty of people like to run their own web-apps instead of relying on third-party services. If that were not true, then WordPress, phpBB, Apache, PHP, etc. would not be available for general use. As for “Internet audience at large”, I must have missed the part where it was a rule that you are only allowed to ask for help for things that applies to everyone else too; I thought you were allowed to ask for help. Besides, if someone knows of software that fulfills the question, then it is relevant to whomever would download it, and so is not only applicable to an “extraordinarily narrow situation”. (Besides, the reason that I was asking was because Google had announced that it was discontinuing FTP support for Blogger and so many people were affected—read NOT TOO LOCALIZED—and were trying to find alternatives.) Hi, I am trying to find software (for Windows, PHP, MySQL/SQLite/flat, free, open-source) to localize all of my software and service so that I can keep my files and host when needed from my own system instead of some remote computer. I’ve already selected things like web, FTP, and db servers. I’ve chosen forum and wiki software, as well as an RCS system. At this point, all I’m still looking for—actually, I still need to choose bug-tracking software, but besides that—is blogging software. I still use Blogger and am trying to find something that I can use to import my Blogger stuff and store on (and publish to) my home system. I have read of various blogging software including WordPress, MovableType, and TextPattern. The problem is that I am trying to find something that is like Blogger (which from what I can tell is not available on Google Code as open-source). What I specifically need is multiple-blog support. That is, multiple blogs ala the Blogger Dashboard, not multiple user accounts (although that is important as well). The closest thing that I have been able to find is using Wordpress categories to simulate multiple blogs, but that’s not really what I want. I want software that I can run locally that has a multi-blog dashboard like Blogger. Any ideas? Thanks a lot!

  • How to advertise (free) software?

    - by nebukadnezzar
    I'm not sure if this fits on SO, but other SE sites don't seem to fit either, so I understand when this question gets moved, Although I'd like to avoid getting it closed due to being offtopics, since I think that this question might fit, considering this part of the FAQ: Stack Overflow is for professional and enthusiast programmers, ... covers … a specific programming problem ... matters that are unique to the programming profession Sorry for the lengthy Introduction, though. When Software is advertised, it is usually Software for one (or more) specific purpose, such as: Mozilla Firefox - A Web Browser Ubuntu - An Operating System Python - A Programming Language Visual Studio - A Development Studio ... And so on. But when writing Libraries, that is, Software that doesn't necessarily serve one specific purpose, but instead multiple purposes, which are usually supposed to be used inside an application, such as: Irrlicht - A 3D Engine Qt - An Application Framework I'm a developer of the latter kind of Software, and I naturally want to advertise my Software. It's not commercial Software; It's not GPL either. It's completely free (Licensed under the MIT License :-)). I naturally host my stuff at github, which technically makes it very easy to access the software, and I thought that these might be possible options, although I have no experience with them: Submit the Software to Freshmeat, and hope for the best Submit the Software to Sourceforge, and hope someone accidently stumbles over it Write spammails, and get death threats via Mail ... But something tells me that these methods are probably not the best Methods. So, my final question would be, How does the Average Joe Hobby Programmer advertise his/her Software Library? Yes, I know this question is probably getting closed due to being Offtopic on SO. But maybe a move might be better instead.

  • Beginners guide to developing optimization software

    - by Florenc
    I am novice in "serious" programming i.e. applications that deal with real-life applications and software projects that go beyond school assignments. My interests include optimization, operations research, algorithms and lately i discovered how much I do like software design/development/engineering. I have already developed some simple desktop applications for some "famous" problems like TSP using heuristc approaches, a VRP solver (in progress) and so on. While developing this kind of software I actually used basic concepts taught at school such as object-orientation analysis and design. But, I found these courses rather elementary and quite boring (for my expectations). So I decided to go a little further and start developing "real" software (and this is where I realized how important and interesting software engineering/design is.) Now, here's my issue: I can not find a "study guide" for developing software of this kind. Currently, there are numerous resources out there (books, websites, tutorials) in designing and developing complex IS, web applications, smartphone apps but I can't find a book for example entitled "optimization software development". Definetly, someone could claim that "design patterns apply to software in general" but that's not my point. My point is that I could simply use my imagination for "simple" implementations, but what happens, when my imagination can not go further? In other words I'm looking for a guide/path to bridge the gap between: Mathematics-Algorithm Design-Software Engineering-Optimization-Software development

  • Does chunk size affect the read performance of a Linux md software RAID1 array?

    - by OldWolf
    This came up in relation to this question on determining chunk size of an existing RAID array. The general consensus seems to be that chunk size does not apply to RAID1 as it is not striped. On the other hand, the Linux RAID Wiki claims that it will have an affect on read performance. However, I cannot find any benchmarks testing/proving that. Can anyone point to conclusive documentation that it either does or does not affect read performance?

  • Preseeding Ubuntu partman recipe using LVM and RAID

    - by Swav
    I'm trying to preseed Ubuntu 12.04 server installation and created a recipe that would create RAID 1 on 2 drives and then partition that using LVM. Unfortunately partman complains when creating LVM volumes saying there no partitions in recipe that could be used with LVM (in console it complains about unusable recipe). The layout I'm after is RAID 1 on sdb and sdc (installing from USB stick so it takes sda) and then use LVM to create boot, root and swap. The odd thing is that if I change the mount point of boot_lv to home the recipe works fine (apart from mounting in wrong place), but when mounting at /boot it fails I know I could use separate /boot primary partition, but can anybody tell me why it fails. Recipe and relevant options below. ## Partitioning using RAID d-i partman-auto/disk string /dev/sdb /dev/sdc d-i partman-auto/method string raid d-i partman-lvm/device_remove_lvm boolean true d-i partman-md/device_remove_md boolean true #d-i partman-lvm/confirm boolean true d-i partman-auto-lvm/new_vg_name string main_vg d-i partman-auto/expert_recipe string \ multiraid :: \ 100 512 -1 raid \ $lvmignore{ } \ $primary{ } \ method{ raid } \ . \ 256 512 256 ext3 \ $defaultignore{ } \ $lvmok{ } \ method{ format } \ format{ } \ use_filesystem{ } \ filesystem{ ext3 } \ mountpoint{ /boot } \ lv_name{ boot_lv } \ . \ 2000 5000 -1 ext4 \ $defaultignore{ } \ $lvmok{ } \ method{ format } \ format{ } \ use_filesystem{ } \ filesystem{ ext4 } \ mountpoint{ / } \ lv_name{ root_lv } \ . \ 64 512 300% linux-swap \ $defaultignore{ } \ $lvmok{ } \ method{ swap } \ format{ } \ lv_name{ swap_lv } \ . d-i partman-auto-raid/recipe string \ 1 2 0 lvm - \ /dev/sdb1#/dev/sdc1 \ . d-i mdadm/boot_degraded boolean true #d-i partman-md/confirm boolean true #d-i partman-partitioning/confirm_write_new_label boolean true #d-i partman/choose_partition select Finish partitioning and write changes to disk #d-i partman/confirm boolean true #d-i partman-md/confirm_nooverwrite boolean true #d-i partman/confirm_nooverwrite boolean true EDIT: After a bit of googling I found below snippet of code from partman-auto-lvm, but I still don't understand why would they prevent that setup if it's possible to do manually and booting from boot partition on LVM is possible. # Make sure a boot partition isn't marked as lvmok if echo "$scheme" | grep lvmok | grep -q "[[:space:]]/boot[[:space:]]"; then bail_out unusable_recipe fi

  • Using mixed disks and OpenFiler to create RAID storage

    - by Cylindric
    I need to improve my home storage to add some resilience. I currently have four disks, as follows: D0: 500Gb (System, Boot) D1: 1Tb D2: 500Gb D3: 250Gb There's a mix of partitions on there, so it's not JBOD, but data is pretty spread out and not redundant. As this is my primary PC and I don't want to give up the entire OS to storage, my plan is to use OpenFiler in a VM to create a virtual SAN. I will also use Windows Software RAID to mirror the OS. Partitions will be created as follows: D0 P1: 100Mb: System-Reserved Boot D0 P2: 50Gb: Virtual Machine VMDKs for OS D0 P3: 350Gb: Data D1 P1: 100Mb: System-Reserved Boot D1 P2: 50Gb: Virtual Machine VMDKs for OS D1 P3: 800Gb: Data D2 P1: 450Gb: Data D3 P1: 200Gb: Data This will result in: Mirrored boot partition Mirrored Operating system Mirrored Virtual machine O/S disks Four partitions for data In the four data partitions I will create several large VMDK files, which I will "mount" into OpenFiler as block-storage devices, combined into three RAID arrays (due to the differing disk sizes) In effect, I'll end up with the following usable partitions SYSTEM 100Mb the small boot partition created by the Windows 7 installer (RAID-1) HOST 50Gb the Windows 7 partition (RAID-1) GUESTS 50Gb Virtual machine Guest VMDK's (RAID-1) VG1 900Gb Volume group consisting of a RAID-5 and two RAID-1 VG2 300Gb Volume group consisting of a single disk On VG1 I can dynamically assign storage for my media, photographs, documents, whatever, and it will be safe. On VG2 I can dynamically assign storage for my data that is not critical, and easily recoverable, as it is not safe. Are there any particular 'gotchas' when implementing a virtual OpenFiler like this? Is the recovery process for a failing disk going to be very problematic? Thanks.

  • Package upgrade on Ubuntu raid server and grub setup issue

    - by RecNes
    I have remote Ubuntu 10.10 server running on raid system. I did package upgrade yesterday night for security reasons. During the upgrade, grub installation screen appeared and asked me which partition I wanted to install grub. Options are sda,sdb,md1 and md2. I decide to install them on both sda and sdb partitions. I wondering, was I make true decision? If machine get reboot is it can be boot up safely?

  • RAID-capable 3.5" SATA Drives

    - by nroam
    I recently purchased a pair of 1TB Western Digital WD1002FBYS RE3 drives for use in an external RAID enclosure. I have found that they tend to drop out of the array after a while. Thinking it was the enclosure I tried them on another one but found the same issue. So a bit of googling and I found http://www.tomshardware.com/forum/251076-32-raid-issues-western-digital-hard-disk which suggests that: "WD's "RE" (RAID Edition) HDDs support Time-Limited Error Recovery ("TLER" ): http://www.wdc.com/en/products/productcatalog.asp?language=en As a non-TLER HDD fills up with data, the error detection firmware might take too long, and the RAID controller may drop that HDD from a RAID array." So now I wonder what SATA drives have firmware which is compatible with RAID arrays (esp. RAID 1, 5, but not 0)? I have not been able to come up with the magic set of keywords to ellicit the answer from Google. However, various sites suggest that Seagate & Hitachi are in general OK. Does anyone have any generic (or even specific) guidance on how to work out if a drive's firmware may harbour code that is potentially an issue in a RAID0 setting other than stating that it must be 'enterprise' ready?

  • Fake RAID (dmraid) not seeing new SATA drives

    - by rausch
    I have three drives in my machine, one SSD with 32GB and two 1TB drives, attached to an Intel 82801JI (ICH10) SATA AHCI Controller. The problem is, that I can access only one of the 1TB drives when the other one is not plugged in. When it is plugged in I see the drives as sda and sdb, but there seem to be no partitions. Looking at these drives with cfdisk, the partitions are there, though. Both of the 1TB drives are carrying a partition, being part of a software RAID1, created with mdadm. Before I threw the SSD into the mix, the other two have been working fine. Any hints?

  • Useful software for netbook?

    - by Moayad Mardini
    I'm looking for recommendations of good software that are particularly useful for netbooks. Software that run great on small screens and low CPU/RAM requirments. I'll start off with the following : Operating Systems: Ubuntu Netbook Remix. Easy Peasy: A fork of Ubuntu Netbook Remix that was once called UBuntu EEE. It isn't just for eeePCs though. Definitely worth a look if vanilla Netbook Remix isn't cutting it. (MarkM) Damn Small Linux (Source) Windows 7: With trimming the installation or compressing the Windows directory to fit on an 8GB SSD. (Will Eddins) nLite: A utility to install a lightweight version of Windows XP without the unnecessary components (like Media Player, Internet Explorer, Outlook Express, MSN Explorer, Messenger...). Utilites: TouchFreeze: To disable the touch pad while typing (Source) InSSIDer: Not only does it make it easier to find and keep a wireless connection, but it turns a netbook into the perfect mobile tool for troubleshooting wireless networks. (phenry) AltMove: Adds more functionality to your mouse for interacting with windows. (Rob) ASUS Font Resizer Utility and other tools by ASUS, specific to ASUS Eee PC series. Internet: Run FileZilla FTP client for a small screen : You can hide a lot of FileZilla's interface parts in the View menu, even the directory trees. Go into Settings = Interface and move the message log next to the transfer queue, if you haven't hidden them both or you want to see them. Select a theme with 16x16 icons. (Source) IDEs and Text Editors: Best lightweight IDE/Text Editor: A question on Stack Overflow that has many good suggestions of IDEs and general text editors for programmers. What’s a good linux C/C++ IDE for a low-res screen?: IDEs for Linux-powered netbooks. Online tools: Dropbox: Since the Netbook has limited disk space, you would like to use Cloud Apps like Dropbox and Ubuntu One so that you don't run out of space especially if you are on a holiday. Later when you go back to your desktop with big hard disk,you can take out the files from your dropbox repo. (Manish Sinha) Google products: like Docs, Calendar and Reader (aviraldg) Web sites and software lists: Netbookfiles.com: Netbook specific software downloads. Software Apps to Maximise your Netbook Battery Power: Netbooks are known for their portability. Not only are they small and lightweight but with their increased power efficiency, batteries can last much longer than conventional laptops. This also means you no longer have to carry a power adapter with you! Several brands emphasis the longevity of the battery as a strong selling point, and for those people who travel a lot, it sure is. Free Must-Have Netbook Apps: Finding software for netbooks can present challenges due to limited hard drive space, processor power, RAM, and screen real-estate. That doesn't mean you have to do without essential programs. The apps below cover all the bases -- entertainment, productivity, security, and communication -- without compromising on performance or usability. Best of all, they're free! Useful Netbook Software: With short battery lives and small resolution screens Netbooks, unlike many other computers on the market, could so with some specific software for their use. Now, not all of those I’ve found are specifically designed for Netbooks, but all are relevant. And they’re designed for Windows XP. The question is community wiki, so feel free to edit it. Updated, thank you all for suggestions.

  • Hardware RAID Controller Support for SSD TRIM

    - by dss539
    Do any hardware RAID controllers available today support TRIM? If not, do any manufacturers have target dates for supporting TRIM? Should I even care about TRIM for SSDs installed in performance-sensitive workstations? Before you suggest it, yes software RAID would sidestep the issue, but my requirements do not allow software RAID. edit: The answer appears to be "no RAID controllers support TRIM" at the current date.

    I want to learn how to use Software Raid 10, is it possible to use VirtualBox by adding four storage images? This is my plan: 4x 100mb partitions (1 on each drive) configured as a raid 1 for /boot in ext3. Then with the remaining space on each drive, setup a software raid partition and configure it to to LVM and raid 10. In the LVM, set up a 4gb swap partition and the remaining space as the root partition ( / ) as ext3.

    I'm building a Raid array for the first time in my system and I have a question regarding having multiple Raid 1 arrays in a single Win 7 system. I'm a bit of an organizational freak with my data and I currently have two separate hard drives I want to mirror. The new motherboard I'm looking to buy supports Raid, so my question is this: a) can I have more than one Raid 1 array in a single system? b) would I have to buy a separate controller for the second array?

  • raid 0 failure, drives look fine

    - by Alan
    Hello, after a lovely blue screen my vista 64 machine decided to reconfigure one of my drives to no longer be part of my raid volume. So now my raid fails as it only has one member disk. This happened to me about 6 months ago and I just changed the disk in question back to a raid disk and all was well. However I cant seem to find that option in my bios or raid config anymore :( Any help would be appreciated
