Raid10 Recovery problem
Posted: 03 Jun 2014, 06:51
Looking for advice from the experts out there...
I just had a failure on a 4x3TB RAID10 due to a BIOS reset. Similar to other stories, I had to manually change the BIOS setting back to RAID, then two discs appeared as non-member. I re-created the RAID with the same settings, and as my OS is on a dedicated SSD, I ran Testdisk in Windows 8.
After 3 days of quick scanning (is this normal?) here are the results:
Looking at the last (large) partition, I saw all of my data / directories, everything looked intact, so I set this partition to primary, write / confirm. Then into the boot menu, and both boot sectors were bad. I selected Rebuild, then quit, reboot
The volume appeared in Windows after rebooting, but the first thing I noticed was that it only appeared as ~2TB and my directory structure was there, but none of my files were opening... everything seemed to be corrupt! I went into disk management and noticed a huge "unallocated" partition of over 2TB, and another smaller partition at the beginning, of unallocated space.
After realizing I probably made a huge mistake by restoring this partition and writing a new BS, I am running Testdisk again this time in deep scan. Here is what I see so far:
My question...am I wasting my time at this point? Is my volume gone? Also, what is the mismatch error? Did I stripe the volume incorrectly when I rebuilt it? I forget what it originally was but I thought I kept it at the suggested value which is 64KB.
I am thankful that I got to at least see the directory structure and what I had on the volume, so that I know what I lost, but if there's any chance of saving the volume and rebuilding the partition properly, please let me know what I should do!
thanks
