Hi,
My 4TB ext4 RAID-6 has just become damaged for the second time in
two months. While I do have backups for most of my data, it would
be good to know if there is a recovery procedure or a way to avoid
these crashes. The symptoms are massive group descriptor
corruption, similar to what was mentioned in
http://thread.gmane.org/gmane.comp.file-systems.ext4/10844 and
http://article.gmane.org/gmane.comp.file-systems.ext4/11195 .
What kind of RAID 6 device are you using? Is it MD raid or some vendor array?
md, as shown in the linked config and dmesg.
