  1. Thank you! This will be a life saver.... I guess I can fire off this order from amazon it is going to hurt the wallet... a bit, but if it is as easy as that article is hopefully it will only be a pain there and nowhere else. The failed drive is covered through 2013, so I will probably get it RMA'ed and have 2tb of more space...
  2. Hi guys, My wife informed me tonight that our server had crashed. The web interface was not responding, and Samba advertised all of the user shares, but I was unable to browse them. I proceded to follow the instructions on the wiki to shut down the array from the command line, but it hung. After waiting 30 mins or so I ran reboot -n. When the box came back up my tower status was amber, and one of my data drives had a red indicator. I then searched the forums and did some basic troubleshooting. Powered down changed power/sata cables etc.. At this point I am ready to order a drive to replace the failed one and then troubleshoot that drive offline, and RMA it if I must... but I have one problem... The problem: I have a 2tb parity drive. I would like to order a 3tb drive for the new drive, and swap the parity out... but I don't believe this is possible with the status of the array. Is there any way that I could accomplish this with out having to bring a 2nd new drive into the equation? Is there some way that I could copy the parity data to the new 3tb drive, so that I can use the current parity drive as a replacement of the bad data drive...? Thanks! PS: Odd thing is that drive seems to have passed the smartctl (Ran while the indicator was red) Model Family: Western Digital Caviar Green (Adv.

  3. Hey guys. I installed a new raid card, the 4 Port Adaptech that is suggested on the raid card controller thread. When I run preclear_disk.sh against it only clears at 2.6MB/s. I can't seem to figure out why it is going so slow. I have a Biostar H55: http://www.newegg.com/Product/Product.aspx?Item=N82E16813138307&cm_re=biostart_H55-_-13-138-307-_-Product I am not sure if this is normal or if there is anything I needed to do in the bios. Please let me know if you need further information.
  4. I have a 9 bay tower that will max out before I hit the unraid max. Unfortunately I do not have anywhere in my house to place a rack mount depth case, so I was looking at this as an option to expand past my current limitation.
  5. Would this work for unraid if it was configured as JBOD? New egg shell shocker: http://www.newegg.com/Special/ShellShocker.aspx?cm_sp=ShellShocker-_-16-111-166-_-07112011_3
  6. A lot of onboard raid controllers support raid 10. It is just a striped raid array that is then mirrored. My company has many VMWare servers, and all of the disk shelves are raid 10. It was very noticeable early on that raid5 was not a good choice for a server running multiple VMs.
  7. Woh, Raid5 sucks for VMs. If you are going for preformance in your VMs you would want to go raid 10. You could probably raid 10 4 2tb drives, and get 4tb of redundant fast storage.
  8. HALP! Today I noticed that my vm was being unexpectedly stopped. Now I can't start (via VBoxManage startvm <VM Name> -type headless> I see the following in the syslog: Feb 27 01:39:03 Tower kernel: VBoxHeadless invoked oom-killer: gfp_mask=0x304d2, order=0, oom_adj=0 (Minor Issues) Feb 27 01:39:03 Tower kernel: Pid: 13004, comm: VBoxHeadless Not tainted 2.6.32.9-unRAID #8 (Errors) Feb 27 01:39:03 Tower kernel: Call Trace: (Errors) Feb 27 01:39:03 Tower kernel: [<c104ab61>] oom_kill_process+0x59/0x1cd (Errors) Feb 27 01:39:03 Tower kernel: [<c104afb9>] __out_of_memory+0xef/0x102 (Errors) Feb 27 01:39:03 Tower kernel: [<c104b02a>] out_of_memory+0x5e/0x83 (Errors) Feb 27 01:39:03 Tower kernel: [<c104cfe9>] __alloc_pages_nodemask+0x375/0x42f (Errors) Feb 27 01:39:03 Tower kernel: [<f85d3e4b>] rtR0MemObjLinuxAllocPages+0xad/0x163 [vboxdrv] (Errors) Feb 27 01:39:03 Tower kernel: [<f85d3f28>] rtR0MemObjLinuxAllocPhysSub2+0x27/0xd1 [vboxdrv] (Errors) Feb 27 01:39:03 Tower kernel: [<f85d4079>] rtR0MemObjLinuxAllocPhysSub+0xa7/0xb2 [vboxdrv] (Errors) Feb 27 01:39:03 Tower kernel: [<f85d409e>] rtR0MemObjNativeAllocPhysNC+0x1a/0x1c [vboxdrv] (Errors) Feb 27 01:39:03 Tower kernel: [<f85d2812>] RTR0MemObjAllocPhysNCTag+0x55/0x6a [vboxdrv] (Errors) Feb 27 01:39:03 Tower kernel: [<f85d04b2>] ? supdrvIOCtl+0x1165/0x245a [vboxdrv] (Errors) Feb 27 01:39:03 Tower kernel: [<f85d3712>] ? rtR0MemAllocEx+0x60/0x90 [vboxdrv] (Errors) Feb 27 01:39:03 Tower kernel: [<f85d3712>] ? rtR0MemAllocEx+0x60/0x90 [vboxdrv] (Errors) Feb 27 01:39:03 Tower kernel: [<f85cc287>] ?

It says out of memory, but my box has 8gb of memory, and I only have 1.5gb assigned to this vm.

  9. I try to exclusively download x264. My apple TV running XBMC was able to decode a XviD DVD rip no problem with no lag. I think it is only the higher end content in XviD that tends to cause issues because it is software decoding. Now days you should be able to find all HD content in x264... My wife had one issue with an old Xvid Disney movie, and i think that one had poor encoding, the other movies in the same movie pack had no issue. I just loaded up a converting program and converted that one file over to x264, bye bye problems.
  10. I was able to download the nano source and complie it under my unRaid build. I know vi is cool and hacky and all, but nano is so much more strait forward and fast... I am on that box via ssh editing for maybe an hour once a month...
  11. 75MB /s? I've never seen anything near that! My cache drive is a WD EARS drive. I considered getting a faster cache drive, but I like the idea of having it as a warm spare and I'm trying to stick with green drives... Maybe when I get my new case (norco 4224), I'll pick up a WD Black at the same time and have an extra green drive in an empty slot... You don't need a 2tb cache drive. If you use a PC when you upgrade your desktop next take the 7200rpm drive out of there. Bam instant cache drive. I am not afraid of my cache drive dieing, I backup the .custom folder periodically so if it does die due to being an older performance drive big deal. I have SAB/Sickbeard, and Sickbeard moves completed items to the user share when they are done downloading (few more spin-ups than waiting for the mover but they are safe) My mover runs 4 times a day to keep things in check (it does this b/c the cache drive is an old 7200rp 120gb HD.)
  12. I've actually had luck with acetone in those cases- the diluted variety (fingernail polish remover). About 3-5 seconds does wonders sometimes. It's easy to overdo it. I practiced on a lot of junk discs, but it works. I use the dish soap method... Sounds crazy but it works. Take your favorite dish soap, flip the disk data side up, and put a nice sized drop on there. Gently press and move the dish soap around in a circle. Supposidly dish soap has some wax in it, and that will settle in the cracks. After you are done rubbing the soap in wait 30 seconds or so, rinse it off. Pat it dry to remove any water spots from the data side, and let it sit to dry. This method usually takes care of discs with a lot of small scratches. If there are gouges good luck.
  13. From what I have read and heard you basically want parts that have been used in one mac or another. Just check out the proc and video card to see if the were ever in a mac. That way you can run as close to a stock kernel as possible. Basically a core2 duo w/ a GeForce chipset should be fine.
  14. How often do you want to run backups? If you wanted to be super cheap and lasy.... you could buy some hot swap drives, and make sure your sensitive data gets stored to a specific disk, once a month swap out the HDD assigned to that disk and have the array rebuild it... I would say a platter solution is more reliable than a SSD. If something happens and a platter drive dies you can still recover data... send the disk to a lab and they can pull data off (may be very expensive) I am not sure how possible this is with a SSD, there is no magnetic platter that they can analyze to pull the data off of...
  15. you can have it any position you want. Just make sure that you aren't preventing any airflow... heat is bad...
