I am completely lost :( I got software RAID10 with 4 drives, one of them failed yesterday, right before or after the failure system crashed and restarted. It started data rebalancing and completed it successfully, however it still can't mount raid10 partition due to file system errors. When tryin to do: mount /dev/md2 /mnt/
It gives an error in syslog: EXT4-fs (md2): ext4_check_descriptors: Checksum for group 1920 failed (12014!=34594)
Naturally I started fsck on that partition. It ran for almost a day, and pretty much stuck fixing multiple-claimed blocks. Seems like every singly inode has thousands of them.
Is it possible to mount corrupted ext4 to get whatever data out of it that I can get? If not, will letting fsck complete the procedure(could take weeks) will help anyhow?
