Hi,
I'm trying to resize/reshape some of my arrays:
md1 : active raid1 sdc5[1]
9767424 blocks [2/1] [_U]
bitmap: 48/150 pages [192KB], 32KB chunk
% mdadm --grow --size max /dev/md1
mdadm: Cannot set device size for /dev/md1: Device or resource busy
and dmesg says:
md: couldn't update array info. -16
md2 : active raid5 sdc2[6](S) sde2[3] sdg1[1] sdf3[4] sdd1[5] sdb1[2]
sda1[0]
945625280 blocks level 5, 64k chunk, algorithm 2 [6/6] [UUUUUU]
bitmap: 0/181 pages [0KB], 512KB chunk
% mdadm --grow -n 7 /dev/md2
mdadm: Need to backup 1920K of critical section..
mdadm: Cannot set device size/shape for /dev/md2: Device or resource busy
and dmesg says:
md: couldn't update array info. -16
% uname -a
Linux frosties 2.6.29.4-frosties-1 #8 Sun Jun 7 00:48:55 CEST 2009 x86_64 GNU/Linux
% mdadm --version
mdadm - v2.6.9 - 10th March 2009
Anyone have an idea what is wrong there?
MfG
Goswin
