Volume expansion seems inactive
Hello, Volume expansion seems to be running for 2 days now but I have no sign of progress within the GUI. See the HDD sizes and the actual disk space. Something is wrong but I don't know what. So...
The screenshots aren't showing because images are reviewed by a moderator before they are published (just in case someone posts something inappropriate). Once a moderator approves them they will then show.
I can't see your screenshots, but what you are looking for is to see a resync with a percentage indicator of progress.
You can alternatively copy and paste the text from the output of
watch /cat/proc/mdstat
rather than post a screenshot.
The code tag option (see the </> button) is very good for posting that kind of output.
Say you are using X-RAID you would have md0 (4GB OS volume), md1 (swap) and md127 (data volume).
If you had say 3 disks installed and added a fourth you should see the 4th disk added to md0, md1 and md127. The md0 and md1 resyncs are very quick, but the md127 one would take a while.
If you replace a disk with a higher capacity disk, not only will md0, md1 and md127 need to be rebuilt, but if you have at least two disks of the higher capacity installed a new layer md126 would be added (note this is just an example md127 could be the new layer showing and md126 the one already present).
Once the resyncs have finished you should no longer see a rebuild status or percentage for any of the RAID arrays. The data volume should then expand provided your additions have met the requirements for expansion for the RAID level you have chosen.
If it doesn't expand you could see if a reboot helps.
Here's an example from a redundant single-layer volume with 6 disks:
root@MDGM-NAS:~# cat /proc/mdstat
Personalities : [raid0] [raid1] [raid10] [raid6] [raid5] [raid4]
md1 : active raid10 sdg2[5] sdf2[4] sdd2[3] sdc2[2] sdb2[1] sda2[0]
1569792 blocks super 1.2 512K chunks 2 near-copies [6/6] [UUUUUU]
md127 : active raid6 sdg3[6] sda3[0] sdf3[5] sdd3[3] sdc3[2] sdb3[1]
23422691328 blocks super 1.2 level 6, 64k chunk, algorithm 2 [6/6] [UUUUUU]
md0 : active raid1 sdg1[6] sda1[0] sdf1[5] sdd1[3] sdc1[2] sdb1[1]
4190208 blocks super 1.2 [6/6] [UUUUUU]
unused devices: <none>- Finally the screenshots are here. Now you can review my issue. Can you help? And please layman words
I think I get it. I have 3 X 3Tb HDDs and 3 X 4Tb HDDs. But historically I started the NAS with with 6 X 3Tb HDDs.
That little f***** stayed with 3Tb disks all the time, which explains why the volume shows a capacity of 14Tb.
Why did this happen? I thought the volume expansion was automatic. Obviously! Since there is nothing proposed about expansion in the GUI.
How do I solve that now? Or are my 3 extra terrabytes wasted forever?

Or are my 3 extra terrabytes wasted forever?When you say you started with 6 x 3TB, you installed them initially or did a factory default with all installed, or did you start with fewer and add them along the way before switching to 4TB? That's important for the expansion limitations, one of which is the volume cannot expand more than 8TB total.
If you have run into an expansion limit, then a backup, factory default, and restore is the only way around it. You may then want to consider upgrading to OS6, which has no such limits.
