Hi, I tried to start a reshape over the weekend (RAID6 -> RAID5) and was dismayed to see that it was going to take roughly 2 weeks to complete: md0 : active raid6 sdc[0] sdh[5](S) sdg[4] sdf[3] sde[2] sdd[1] 5860543488 blocks super 0.91 level 6, 64k chunk, algorithm 2 [5/5] [uuuuu] [>....................] reshape = 0.0% (245760/1953514496) finish=21189.7min speed=1536K/sec The disk that contained the backup file began experiencing SATA errors several days into the reshape, due to what turned out to be a faulty SATA card. The card has since been replaced and the RAID1 device that contains the backup file successfully resync'ed. However, when I try to re-start the reshape now, I get the following error: nas:~# mdadm --assemble /dev/md0 --backup-file=md0.backup /dev/sdc /dev/sdd /dev/sde /dev/sdf /dev/sdg /dev/sdh mdadm: Failed to restore critical section for reshape, sorry. Is my data lost for good? Is there anything else I can do?
