You can just continue to try:

Code: Select all

[root@TNAS-???? ~]fuser -m /mnt/md0
[root@TNAS-???? ~]fuser -mk /mnt/md0
[root@TNAS-???? ~]umount /mnt/md0
[root@TNAS-???? ~]vgchange -an vg0
[root@TNAS-???? ~]presize /dev/md0
[root@TNAS-???? ~]vgchange -ay vg0
[root@TNAS-???? ~]lvextend -l +100%100FREE /dev/vg0/lv0
If you enter vgchange -an vg0 and it still shows that vg0 cannot be found, you can proceed directly to the next step.

i sent email, waiting for response.

also your linked page has many typo errors on the commands.

"presize /dev/md0" >> resize /dev/md0

btrfs filesystem resize max /mnt/md0 >>
For btrfs filesystem use this command:
resize max /mnt/md0


[root@TNAS-???? ~]ext4 resize2fs /dev/vg0/lv0
FOR ext4 use this command:
[root@TNAS-???? ~]resize2fs /dev/vg0/lv0

+100%100FREE >>> +100%FREE ???

also so many confusing lines, and only md0 is relevant, but commands so far mostly failing...
The following example is based on "md0, vg0, lv0"
Your "array, pool, Volume" may not be "md0, vg0, lv0".
Please use the following instructions to confirm:
Instructions are flawed somehow, whoever written this, didnt check it?

i dont know what else to do... something is messed up, now also my PLEX server is corrupted, because nowehere in the guides said you have to stop PLEX or ANY OTHER SERVICES that may interfere or cause problems for raid expansion process!

now i have followed the instructions set out in the forums, and it still didnt complete correctly... and the fix is really confusing and incomplete (due to typos and expectation of end user's knowledge on linux commands)

i cant say i m really happy... but i will wait until technician response for remote help. also "office hours" for technicians, which country's office hours are these?
