mdadm 3.14
kernel 2.6.35.8
I started a reshape changing chunk size and after it ran
for a while i realized the disk i used for the
backup file was slow so I killed the mdadm
running in the background and tried to restart
with the new location (i moved the file just in case)
mdadm /dev/md5 --grow --chunk=8 --backup-file=/my/raid/RAID_BACKUP_FILE
it complains:
mdadm: /dev/md5 is performing resync/recovery and cannot be reshaped
/proc/mdstat for md5 shows partial progress but the numbers don't change
(except finish grows):
md5 : active raid6 sdd1[2] sdf1[8] sdc1[1] sdb1[0] sdh1[4] sdl1[5]
sdj1[3] sdg1[7] sdk1[6]
13674583552 blocks super 0.91 level 6, 128k chunk, algorithm 2
[9/9] [UUUUUUUUU]
[>....................] reshape = 0.1% (2715648/1953511936)
finish=850711.5min speed=38K/sec
The mdadm 3.14 is freshly compiled. I started the reshape
with mdadm 3.13.
I didn't try rebooting as the filesystem is mounted and
the data seems ok. Didn't want to make things worse...
Thank you for any help
