SRaid with 13 Disks crashed
Hello,
this seems to be my last chance to get back all of my data from a sw-raid5 with 12-13 disks.
i use debian ( 2.6.32-bpo.5-amd64) and last i wanted to grow the raid from 12 to 13 disk with a size at all of 18tb. after run mke2fs i must see that the tool on ext4 allow a maximum size of 16tb. after that i wanted to shrink the size back to 12 disk and now the raid is gone.
i tried some assemble and examine things but without success.
here some information:
cat /proc/mdstat
