Mixed Disk capacities and strange display of Disks / Status after resilver

[jackydany]

Hi there,

my config:
Truenas Scale 22.12.1
Dell R620
128gb Ram
3 Pools, 2 are used
The used Pools are RaidZ3
Pools out of Netapp DS with 2x 12 4tb HDDs SAS

I had a disk failure on one of the pools.
Truenas took the disk offline, fine because of RaidZ3
So i pulled the disk from the Netapp Diskshelf and replaced it with a different SAS drive.
Replaced the disk via WebUI.
It started resilvering. It already showed a message regarding mixed capacitiy, even though it just started to resilver.

During resilvering, the disk showed write errors and read errors as well.
So i pulled the "same" disk again and replaced it via WebUI again.
This time the resilver went straight on and showed no errors.

But now i have several behaviours that confuse me quite a bit.

1. the pool shows Online, No Disks with erros, topology green checked but a Mixed disk capacities.....
2. if i click on storage, pool status for this pool, then manage devices, i expand the raidz3 tree and see one deivce without disk symbokl in front.
i have twelve disks online, no errors but one disk is missing the symbol. if i select this disk, it states: Disk Info: Disk in unavailable.......
3. i cant start a manual smart test, because the disk is unavailable.

Could anyone help me to figure out why everything seems to be fine, no errors, but there should be a disk missing?

Code:

state: ONLINE
status: Some supported and requested features are not enabled on the pool.
        The pool can still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
        the pool may no longer be accessible by software that does not support
        the features. See zpool-features(7) for details.

Your zpool status doesn't show disk capacities, so I can only comment that your pool is online and healthy according to that.

if i click on storage, pool status for this pool, then manage devices, i expand the raidz3 tree and see one deivce without disk symbokl in front.
i have twelve disks online, no errors but one disk is missing the symbol. if i select this disk, it states: Disk Info: Disk in unavailable.......

A screenshot of that might be helpful. Sounds a little odd, but with zpool status showing all clear, I'd normally trust that better than the GUI.

i cant start a manual smart test, because the disk is unavailable.

smartctl -t long /dev/daX (change daX to your disk identifier)

smartctl -a /dev/daX when done to see the results/progress

Thanks for the reply.
Device sdp isnt in the disk list.
So i dontknow what is happening here :D

Maybereboot the Server? Wouldnt be that big of an issue.

Ok, i had to resilver another disk from the other pool.
after this, irecognized, that there was the mixed disk capacities message as well.
and... i had 2 unassigned disks which could not be true.

so i rebooted.... that fixed it. no unassigned disks, no mixed capacities anymore, all disks are showing the disk symbol and all disks are present.
seems like a little bug in the UI not gathering all informations correctly.
