Message-ID: <6652499.post@talk.nabble.com> (raw)
I have been trying to run:
mdadm --grow /dev/md0 --raid-devices=6 --backup-file /backup_raid_grow
I get:
mdadm: Need to backup 1280K of critical section..
mdadm: /dev/md0: Cannot get array details from sysfs
Software versions:
mdadm version 2.5.3, kernel 2.6.17.13
Note that /dev/md0 does in fact have 6 drives, with 4+2 spares:
linux-nas:~/source/mdadm-2.5.3 # mdadm -D /dev/md0
/dev/md0:

3 8 161 3 active sync /dev/sdk1
4 8 192 - spare /dev/sdm
5 8 176 - spare /dev/sdl
As I said, I am getting an error resizing the array.
Would it need to be unmounted to work properly (It is currently mounted
under lvm)?
Thank you in advance,
mickg
