December 8, 201114 yr Author I am having some ideas, but don't want to proceed without direction. 1) I am thinking I need to correct disk2 before attempting a rebuild on disk3. I could boot to unraid on a different pc, attach only disk2, and run the --rebuild-tree from there. I am nervous about the parity getting out of sync doing this. 2) I am thinking I could have an overheating issue, or some other hardware issue causing the fault. The system seems to be failing only under load. I could swap out the MB, CPU and RAM for my HTPC parts just to test with known good. I think I would have enough SATA ports to run it. 3) I could test for the overheating theory by starting another rebuild and monitoring 'sensors'. I would like to fix disk2 first to hopefully prevent data loss, but I'm not sure how unless I hook it up to another PC. Thanks for the help.
December 13, 201114 yr Author Hey guys. I am still stuck on this. I have hooked up the array to my HTPC, meaning a different MB, CPU, PSU, and RAM. The only common components left are the back plane, the HDDs, the flash drive, the power and network cables, and the SATA controller card. My setup is now: MB: ASUS M4A785-M 785G http://www.newegg.com/Product/Product.aspx?Item=N82E16813131595 CPU: AMD Athlon II X2 245 http://www.newegg.com/Product/Product.aspx?Item=N82E16819103687 RAM: Patriot 2GB PDC22G6400ELK http://www.newegg.com/Product/Product.aspx?Item=N82E16820220174 - Both sticks in Controller Card: Rosewill RC-218 http://www.newegg.com/Product/Product.aspx?Item=N82E16816132018 Hard Drive Array: 1 X Supermicro CSE-M35T-1B 5x3 http://www.newegg.com/Product/Product.aspx?Item=N82E16817121405 Video: Onboard Power Supply: With Case Case: hec 7K09BBA30FNRX http://www.newegg.com/Product/Product.aspx?Item=N82E16811121100 CPU Fan: AMD Stock On a side note, this setup boots the array about 3x as fast. Even reading the unraid image from the flash is much faster. Running reiserfsck --check /dev/md2 yields an error that does not explain what to do. Searching online seems to indicate that I should re-run --rebuild-tree, perhaps with the S option to scan the entire disk, but I do not want to proceed without advice. root@Tower:~# reiserfsck --check /dev/md2 reiserfsck 3.6.21 (2009 www.namesys.com) ************************************************************* ** If you are using the latest reiserfsprogs and it fails ** ** please email bug reports to [email protected], ** ** providing as much information as possible -- your ** ** hardware, kernel, patches, settings, all reiserfsck ** ** messages (including version), the reiserfsck logfile, ** ** check the syslog file for any related information. ** ** If you would like advice on using this program, support ** ** is available for $25 at www.namesys.com/support.html. ** ************************************************************* Will read-only check consistency of the filesystem on /dev/md2 Will put log info to 'stdout' Do you want to run this program?[N/Yes] (note need to type Yes if you do):Yes ########### reiserfsck --check started at Mon Dec 12 12:56:54 2011 ########### Replaying journal: Done.

I anxiously await your help. yes, it is basically saying you need to rerun --rebuild-tree If you want to recover files as well that were deleted, you can add the -S option to --rebuild-tree
December 13, 201114 yr Author Good news, I think. I made it through the --rebuild-tree. It says I had a lot of files that were lost. Flushing..finished Objects without names 7308 Empty lost dirs removed 103 Dirs linked to /lost+found: 479 Dirs without stat data found 58 Files linked to /lost+found 6829 Pass 4 - finished done 177831, 40 /sec Deleted unreachable items 7688 Flushing..finished Syncing..finished I ran a subsequent --check just to make sure everything was good and it came back with no issues. I am going to start the disk3 data rebuild now.
December 14, 201114 yr Author Does a drive rebuild go faster with a cache drive? In my original system without a cache drive I ran around 25MB/sec, I added the cache drive and changed around the drive configuration and it went to 45MB/sec, and now on this system without a cache drive it is running 11MB/sec.

In my original system without a cache drive I ran around 25MB/sec, I added the cache drive and changed around the drive configuration and it went to 45MB/sec, and now on this system without a cache drive it is running 11MB/sec. a cache drive has absolutely nothing to do with the speed to rebuild a data drive. Having ports on the various internal busses on the CPU makes all the difference.
December 17, 201114 yr Author The rebuild of disk3 completed successfully, so I went ahead and bought some new hardware. I'm not sure if it was the MB, CPU or RAM, but the new build will replace it all. It is also possible the corrupt disk2 was causing the problem, and the correction caused it to stop locking, however I think it was hardware. Regardless I will have a better set of hardware to run unraid on. Unfortunately I did lose my data on disk2. Much of it appears to be in the lost+found folder. Is there is a way to recover the file names? Thanks for the help!
