Reuben,
What chunk size did you use?
I can't even get mine to get past this part:
p34:~# mdadm /dev/md3 --grow --raid-disks=7
mdadm: Need to backup 15360K of critical section..
mdadm: Cannot set device size/shape for /dev/md3: No space left on device
Justin.
Just whatever the system selected for the chunk size, ie I didn't specify it
myself ;)
[root@tornado cisco]# cat /proc/mdstat
Personalities : [raid1]
md0 : active raid1 sdc2[0] sda2[1]
24410688 blocks [2/2] [UU]
bitmap: 0/187 pages [0KB], 64KB chunk
md1 : active raid1 sdc3[0] sda3[1]
19542944 blocks [2/2] [UU]
bitmap: 0/150 pages [0KB], 64KB chunk
md2 : active raid1 sdc5[0] sda5[1]
4891648 blocks [2/2] [UU]
bitmap: 2/150 pages [8KB], 16KB chunk
I was working on md1 when I filed the email earlier.
I wonder if the chunk size is left as-is after a --grow, and if this is optimal
or not or if this could lead to issues...
