[SOLVED] incorrect ZFS pool & disk state ?

[cholzer]

Hello!

I am currently test driving proxmox 7 on a test machine and ran into this confusing behaviour.

I created a new RAID10 ZFS out of 4x 120GB drives.


Then I UNPLUGGED the 120GB Samsung SSD yet it still shows up as "ONLINE" in the ZFS stats (both in the webGUI and console)!?


Also the ZFS pool is still healthy even though a disk is gone.

Under DISKS the Samsung SSD is gone, so Proxmox did notice it on some level.


Only after I reboot the system proxmox tells me that the zpool is degraded and a drive is missing.


That does not seem right.....right?

Hi,

my personal observation/impression just this afternoon while removing a disk for physical exchange of a drive: this might happen if that pool is simply unused, e.g. empty with zero VMs/Containers.

Only after something is written to the pool (or for example a setting is changed) that state will change.

Best regards

You are right!
If the disk drops out *while data is read/written* to the pool it does go to 'degraded' and I get a notification from zfs zed.

Thank you!
