an old issue but so far my google-fu has not been able to resolve (some mentioned web pages and links not existing any more does not help).
I recently installed a dead 4TB drive with a 10TB drive and after the volume was repaired it would not let me expand the volume. The array is a multi-disk SHR affair.

Hi all,
an old issue but so far my google-fu has not been able to resolve (some mentioned web pages and links not existing any more does not help).
I recently installed a dead 4TB drive with a 10TB drive and after the volume was repaired it would not let me expand the volume. The array is a multi-disk SHR affair.
if I SSH to the NAS and execute 'print devices' the results are:
print devices
/dev/hda (12.0TB)
/dev/sda (12.0TB)
/dev/sdb (12.0TB)
/dev/sdc (10.0TB) <- the new HDD
/dev/sdd (4001GB)
/dev/sde (4001GB)
/dev/sdf (4001GB)
/dev/md0 (2550MB)
/dev/md1 (2147MB)
/dev/md2 (15.0TB)
/dev/md3 (5001GB)
/dev/md4 (7999GB)
/dev/zram0 (591MB)
/dev/zram1 (591MB)
/dev/synoboot (8382MB)
total storage is 25.1GB, but should expand to 31.something GB I guess.
My parted doesn't support 'resizedisk' as it is version 3.1
the LVM is vg1000
mdadm --detail /dev/md2 | fgrep /dev/
/dev/md2:
11 8 5 0 active sync /dev/sda5
10 8 21 1 active sync /dev/sdb5
9 8 37 2 active sync /dev/sdc5
8 8 53 3 active sync /dev/sdd5
7 8 85 4 active sync /dev/sdf5
6 8 69 5 active sync /dev/sde5
if I try the following I cannot expand the partition due to the 'has no superblock' message. I've also tried /md2 and /md4
01> syno_poweroff_task -d
01> mdadm -S /dev/md3
mdadm: stopped /dev/md3
01> mdadm -A /dev/md3 -U devicesize /dev/sdc
mdadm: cannot open device /dev/sdc: Device or resource busy
mdadm: /dev/sdc has no superblock - assembly aborted
Can anyone please assist me with how I can expand the partition on sdc from 4TB to 10TB?
Or would booting up Ubuntu from a USB stick and doing it from gparted be the easiest / quicket way instead of trying to do it locally under SSH?
Thank you.
