• Supermicro SmartOS setup issue with HDDs

  - by Andrew B.

  I'm trying to setup SmartOS on my new Supermicro server (SYS-6027R-N3RF4+). I have 8 HDDs + 2 SSDs installed in the hot-swappable drive bays. I have not configured the Intel RAID controller on the machine (it shows no RAID configured, and lists all 8 HDDs). When I boot SmartOS from my USB key for the first time and get to the initial zpool creation I only see 2 disks listed. How can I tell which two drives are being referenced? How can I get SmartOS to recognize all 8+2 drives? Is there a BIOS setting I need to adjust?

• Connecting OS X MacBook Pro to DirecTV DVR

  - by user14293

  I have a DirecTV DVR which soon will be replaced. The local phone carrier has wired fiber-to-the-door and that DirecTV sat service will soon be history. I have irreplaceable video recordings on the DVR's disk I would like to salvage. I'd like to connect my MacBook Pro (OS X 10.5.3) to the DVR (male HDMI to male Thunderbolt) and treat the MAC as a TV monitor. I'd like to capture the video stream to a file and then burn it to DVD. This is for my use only, not for distribution. Still researching video capture. Don't yet have a solution. Maybe there isn't one. Any ideas?

• How do I get Thunderbird to open an ICS attachment directly in Lightning's calendar?

  - by travis

  I'm using Mozilla Thunderbird 9.0.1 with Lightning 1.1.1. Is there an easier way to import an ICS file attached to an email than saving it to disk, then in Calendar going to File -- Open? If I select "Open with Thunderbird" from the save dialog, it just opens a new mail message and attaches the file to it. (I did see this older question, but it refers to much older versions of Thunderbird and Lightning) Update: I've updated to 10.0 and 1.2, respectively and it still doesn't work right. Update 2: Bugzilla.

• Photoshop CS4 slowing down, need advice to improve speed.

  - by Pennf0lio

  Hi, I just recently experienced problem with my Photoshop, It seem that it is slowing down when I am doing graphics design. Big or small files ( from 20 x 20 inch 300 dpi of resolution to 800x600 72 resolution ) it is really slowing down. Particularly when I am panning to my project It just get stuck for a few seconds then back to normal with slow movement. Can you guess what's wrong? I have an updated antivirus and I don't think virus is causing it. other adobe suite is working fine just my photoshop. I am running in windows 7, using Intel Core2 Duo 2.40 Ghz and has an Installed Ram of 2 GB. My primary scratch disk has 21 Gigabyte left and the secondary has a 13.89 GB. I need a solution urgently. I am planning to reformat my computer just to resolve my problem.

• tradeoffs of iSCSI vs. AFP when using Time Machine with a NAS?

  - by Ajit George

  I'm setting up a home NAS device (Synology DS409) that I'm planning to use for Time Machine backups (amongst other things). What are the tradeoffs between using iSCSI or AFP to mount the backup volume? The Synology wiki suggests that iSCSI is better if the Mac will be frequently disconnected from the network or sleeping, from the point of view of the volume automatically remounting. What about filesystem consistency? Given that unplugging a USB drive without properly unmounting it often requires the Time Machine volume to be repaired, would iSCSI have the same issues?

• RAID0 array of USB 2 disks, both connected to a single hub. Any benefit?

  - by Josh

  I have two unused USB 2 drives. I wanted to stripe them in a RAID0 configuration for fast disk access for virtual machines. (I find running a VMware virtual machine off a USB2 drive to be painfully slow. Especially Windows Vista) If I have both USB drives attached to the same USB2 hub, will that negate any benefit I gain by creating a RAID0 array? That is to say, is the speed of USB2 the limiting factor or is the speed of the drives? Would I get better performance by attaching one or both drives directly to my computer?

• Which hardware changes require operating system reinstallation?

  - by Mark

  I'm about to upgrade my computer but might keep some parts. Just wandering what I would have to keep to prevent me having to reinstall my OSs, at the moment I have a dual boot setup with ubuntu and windows 7. I'm pretty sure you can't just take your hard drive with the OS on it and put it into a different box and keep going (can you?) but I know you can change the graphics cards, secondary hard drives and ram with out a problem. So what is it that you can't change? The CPU? Motherboard? Thanks for any replies

• Monitoring over Time with Nagios: How?

  - by David

  Nagios in its standard usage monitors with point-in-time checks: either something is - or is not - true. Other tools like SGI's PCP, HP's MeasureWare, and SEC provide monitoring over time - monitoring things like average disk access time over the last five minutes, or other similar items. Is there anything like this for Nagios? I'm already running NDOUtils, which seems like a natural source for such data. I'd like to have something that would monitor and fire off alarms based on a time-based check using historical data. Is there anything like this for Nagios?

• Combine drivers from multiple Win7 installs to single image

  - by MikeyB

  I need to prepare a Windows 7 image with drivers for multiple systems (Lenovo laptops). I currently have an image prepared on one laptop type but need to grab the drivers appropriate for the other laptop types as well to ensure that it works on all systems. From what I can tell, the procedure will be: create a boot CD with imageX take a .wim image prepared on the first type of systems take .wim images from the other systems mount the other images in WAIK extract the drivers from the other images inject the drivers into the first .wim boot a system with the boot CD and redeploy the updated .wim image into the Windows partition take an image of the drive with usual imaging tools This all seems a little too convoluted, but I'm willing to do it to get the proper drivers into the image. This is (seemingly) necessarily complicated by having more than one OS on the disk image. Am I on the right track?

• Can't use sudo on ubuntu

  - by martin.malek

  After update and reboot I get 'user is not in the sudoers file. This incident will be reported.' when trying to call sudo. The problem is that I don't have a GRUB with revovery option. I try to boot from live cd but I'm not able to access the system partition, only the partition with grub. Can I somehow enable the recovery mode in GRUB? Or boot throw the live CD from first hard drive with some option for that?

• Micro sound breaks/interrupts on Windows 7

  - by cand

  Hello all, I've been experiencing strange behavior recently. When listening to mp3 or watching movie or whatever that uses sound, I get micro breaks in sound. It's like it hangs or cuts a fragment for about 0.5s. When I start OS, it's ok, but as time passes it gets worse, to the extent that music is unlistenable being interrupted every 2 seconds. I haven't found any relevance between this behavior and hardware usage, I don't think it's directly related to HDD (or it might be but with significant delay). I have updated soundcard drivers and it didn't help a lot. My system is Windows 7, computer is simple HP laptop, nx7300-Ru374ES with WD Caviar Scorpio Blue hard drive inside and integrated soundcard on it (I can check the model later if it's important). Did anybody encounter such problem ? Maybe it's a common thing on Windows 7 or someone knows how to solve it? Thanks in advance.

• MacBook Pro shutting down instantly after attempt to update firmware

  - by Luke Dennis

  I tried to apply a firmware update on a MacBook Pro 2.4ghz (2008), and after rebooting, the fans kicked up to maximum, the screen lit up, and then it immediately died. Now when I try to boot, it does the same thing: the fans crank to max, the screen lights up, and then it dies after about 2 seconds. Resetting the power manager does nothing. It doesn't stay up long enough to choose another boot drive or boot from CD. I have no idea what else to try. Help?

• What could explain my partitions disappearing on a new SSD with Windows 7?

  - by charlesrandall

  So this morning, I had a fresh install of Windows 7 pro, on a new SSD (Patriot TorqX 128gb), which I just put in to a new Dell Studio XPS 9000. Everything was fine. I booted to windows, no problem. I go to work. 8 hours later, I come home, and I'm greeted by my boot screen complaining about no bootable devices. Windows repair from the Windows 7 pro disk says it can't fix the problem. It doesn't see any windows installs. I boot up GParted, and my SSD is completely unallocated. No space used, no partitions. Perhaps this is related to allowing windows 7 to create a utility partition when I installed? Only thing I can think of. Is there some kind of known hardware issue that can result in an SSD completely wiping itself?

• What software supports full multisession CD burning on windows?

  - by dma_k

  I know, that beating Nero in this field is very difficult. I have looked through best software listed in wiki, also checked the related posts here and here: most of the software either allows you to create ISO image and/or burn the existing image. However I am interested in the following flow: Import previous session Add/rename/remove files and directories Burn new session UltraISO is very good in (1) and (2). But it cannot append a disk with new session. InfraRecorder/CDBurnerXP can do (1) (2) (3) but: InfraRecorder crashes when trying to import some Nero sessions CDBurnerXP does not allow to move files in previous session to another directories. Is anybody here happy with any other free software?

• HTC Android Fails to mount- Mount from computer?

  - by Ben Franchuk

  I Have an HTC Incredible S (S-Off, Rooted, ViperVIVO 1.3.0 ICS) that has seemingly ceased to posses the ability to mount its SD Storage to my computer. For whatever reason, whenever I plug in my device to transfer files from computer to phone and vice versa, the computer, for some reason, cannot actually aces the phone. I get prompted with a window on my phone when I first plug it in, asking me which mode I want to put the device into (Charge mode, tether mode, etc.), and even if I select the "Disk Drive" function, the phone still cannot successfully mount to my computer. The phone itself unmounts itself from the SD and says that the computer is connected, but again, it doesn't work. Is there any way to force mount the device from my computer- either via command or otherwise? This should help in that if I unmount the SD from the phone I should be able to mount it to my computer, from my computer, Correct?

• Photo Management Software for OS X That Supports Multiple Library Locations

  - by Lance Rushing

  I'm looking at the possibility of changing our photo management software. Thinking about Aperture or Lightroom. And want to know if either supports: Having folders/libraries on separate harddrives/Volumes. Tolerates having network folders occasionally connected Snappy interface A solid enough piece of software as not to crash or behave weirdly. [ so the wife doesn't get stuck and have to call me ;) ] Background The wife is photographer and I'm the computer programmer. Our current setup is Picasa, with a "Recent/Working" folder on the local iMac harddrive, and "Archive" folders on NFS mounted Linux Server, Raid 5, for redundant and extra storage capacity. (the Linux server also syncs with Amazon's EC2) Picasa is doing OK, but I get annoyed when it doesn't do behave properly. Usually around issues when the Linux disk isn't mounted. And overall, I wish Picasa seemed a little more polished and snappier. Thanks, Lance

• How can I dual install Ubuntu 10.4 in a Mac Mini with 10.4.11?

  - by Marco Mariani

  I'd like to power-up my aging Mac Mini (1.5GHz Core Solo, 1GB RAM, Tiger 10.4.11) by installing a shiny Ubuntu alongside the current OS. After all, I use Ubuntu for everything save for cleaning my teeth. Since it's my first and only Mac and I have next to no experience with the OS (having used it basically as a media player) I am a little concerned about rEFIt, ELILO, Boot Camp and the fact that it's basically a 4.5 years old unsupported machine and I might get asleep reinstalling everything several times. I've used the live desktop-i386 CD and everything works. I tried with an external USB drive instead of a CD but couldn't make it boot. As for installing Ubuntu, the howtos I've found give several alternatives depending on the model, the OSX version, etc.. but they usually talk about newer machines. Which howto should I follow to repartition, and boot thereafter? Thanks

• decrypting AES files in an apache module?

  - by Tom H

  I have a client with a security policy compliance requirement to encrypt certain files on disk. The obvious way to do this is with Device-mapper and an AES crypto module However the current system is setup to generate individual files that are encrypted. What are my options for decrypting files on-the-fly in apache? I see that mod_ssl and mod_session_crypto do encryption/decryption or something similar but not exactly what I am after. I could imagine that a PerlSetOutputFilter would work with a suitable Perl script configured, and I also see mod_ext_filter so I could just fork a unix command and decrypt the file, but they both feel like a hack. I am kind of surprised that there is no mod_crypto available...or am I missing something obvious here? Presumably resource-wise the perl filter is the way to go?

• reiserfsck --rebuild-tree failed: Not enough allocable blocks

• Automatically encrypting incoming email

  - by user16067

  I have a small website and would like to encrypt incoming email using gpg. Is there a way to force sendmail to check email and encrypt it if its not already encrypted? I'm using GPG on a linux server. Thanks [added]Someone asked what I hope to accomplish. My intent is for the users of the email to become more familiar with seeing thier own email encrypted and losing that fear of the unknown. The side benefit is that the email can't be looked at later down the road. If the email isn't encrypted on its way in, I'm unable to do anything about it. I'm assuming most email would be nosed around with once its already on my hard drive, so GPG would protect against those issues.

• Intel cpu hyperthreading on or off for ibm db2?

  - by rtorti19

  Has anyone ever done any database performance comparisons with hyper-threading enabled vs disabled? We are running ibm db2 and I'm curious if anyone has an recommendations for enabling hyper-threading or not. With hyper-threading enabled it makes it quite difficult to do capacity planning for cpu usage. For example. "With 8 physical cores represented as 16 "threads" on the OS and a cpu-bound workload, does that mean when your cpu usage hit's 50% you are actually running at 100%." What real benefits do I gain with leaving hyper-threading enabled on an intel server running DB2? Does hyper-threading help if you're workload is truly disk IO bound? If so, up to what percentage? These are the types of questions I'm trying to answer. Any thoughts?

• Windows XP runs New Hardware Wizard for usb keyboard and mouse, can't find drivers

  - by Randy Orrison

  I have a PC that up until a couple days ago was working fine. I moved it from one site to another and now when I plug in the USB mouse or keyboard (the same ones that were working previously) XP brings up the New Hardware Wizard. Going through it, the correct keyboard and mouse are identified, but XP can't find the drivers. I've tried manually searching for the driver (using the Have Disk option) - the first file it's looking for is in the c:\i386 directory, but that installs a generic HID mouse device; the system then runs the hardware wizard for a new "unknown" device. The system was SP2, I have installed SP3 in hopes that would help, and I've also downloaded and installed the mouse drivers from Dell's site (there are no specific drivers for the keyboard), with no change. Before I completely reinstall XP, is there anything else I should try?

• IE8 on Win7 - file download results in "C:\ location not accessible."

  - by Soulhuntre

  Ok, an odd problem. For one user on a Win7 x64 system, attempting to download a file with Internet Explorer 8 results in a error "C:\ location not accessible. Access is denied." even though the target location is not on the C:\ drive. No other users have the problem and no other browsers do. The user does not remember deleting any folders recently, and it looks liek no new software has been installed. A checkdisk comes up clean. Any ideas? Ken

• How to truly sync files on Windows 7 so Dropbox notices the changes

  - by Edward Tanguay

  I want a file on my hard drive in Windows 7 to sync to my public dropbox folder. I can do this with: mklink /H "c:\dropbox\Public\test.txt" "c:\data\test.txt" And the first time after I do this, the file c:\dropbox\Public\test.txt is indeed created, and is available online via http://dl.dropbox.com/u/.../test.txt. And when I update the file c:\data\test.txt then indeed the file c:\dropbox\Public\test.txt reflects the changes, however: http://dl.dropbox.com/u/.../test.txt does not reflect the changes since DropBox somehow doesn't get the information that that file was changed. What is a workaround or another solution to this so that any changes in the original file is also reflected in the dropbox URL link?

• WSUS setup on ADS Domain Controller VM

  - by NickC

  How should I setup sharing/directory permissions to allow the following to work: VMHost - Hyper-V partition (not part of domain) ADServer - Active Directory Domain Controller running as guest VM on VMHost \VMHost\Updates disk share for WSUS to put the updates and other local files Problem is what permissions do I need to give to \VMHost\Updates to allow WSUS to work with this directory to avoid "The WSUS content directory is not accessible" error which I am currently seeing. As far as I can tell WSUS runs as "domain/Network Service" account. Question is without adding VMHost to the domain how do I give that user appropriate permissions to this directory? Is there a way that VMHost can be told to trust ADServer and then be able to use users accounts from there? Sort of relates to my other post here: Win 2012 Domain controller VM, should the Hyper-V host be part of the domain? Thanks, Nick
