ReadyNAS 312 - Extend Partition
Hi all,
Would be great if something can assist.
I have a RN312 with new 2 x 6TB HDD, however the NAS is showing only 1TB of total available space, please can some advise how I can expand the volume partitian so it's making use of the full 6TB capacity of the installed volume without doing a factory reset. I have a RAID1.
Thanks in advance.

It is supposed to work the way you expected, so we have to figure out what it is that's stopping it from doing so. The first thing I suggest is toggling off and then back on XRAID. If that doesn't kick it off (give it a few minutes), try re-booting again.
There is some information available either via SSH or in the downloaded .zip file that might give a clue as to the nature of the problem.
Using cat /proc/mdstat from SSH or looking in mdstat.log, how many volumes do you see? You shoud have an md1, md1, md127, and md126, but you probably only have the first three.
Using btrfs fi show or looking in btrfs.log, there should be an entry for the data volume something like this (numbers will differ on yours, this is mine):
Label: '7fc780f2:data' uuid: 9ad0e5b9-a030-4530-a93c-6a337693158d Total devices 2 FS bytes used 22.66TiB devid 1 size 27.27TiB used 22.78TiB path /dev/md127 devid 2 size 3.64TiB used 1.03GiB path /dev/md126
The contents of sgdisk.log and/or partitions.log or output of fdisk -l may also help.
There is a command from SSH that might help: volume_util -e auto

Did you start with two 1TB drives and upgrade to 6TB?
Hi Sandy,
Yes I did, may be I was mistaken and assumed that if I extend to a 6TB and then eventually change both the drives to 6TB, restarting the NAS would recognise that the drives are in fact larger.
Is there any way around this without a factory reset?
Thanks,
Zabir.
