I am trying to convert from raid 5 to raid 6 and I am getting this error:
mdadm: Need to backup 1280K of critical section.. mdadm: Cannot set device size/shape for /dev/md0: Invalid argument
Some info that may be useful:
[root@borg ~]# uname -a Linux borg.loc 18.104.22.168-78.2.56.fc9.x86_64 #1 SMP Thu Jun 18 12:24:37 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux [root@borg ~]# [root@borg ~]# [root@borg ~]# mdadm -V mdadm - v22.214.171.124 - 15th October 2008
From what I've read, My kernel should support this. I also checked the .config file to ensure raid5 resizing is enabled.
I previously was able to go from 3 drives to 5 with no issues but now that I'm trying to go raid6, no go. Any help would be appreciated, thanks!
