Hi there...
I've installed Proxmox with ZFS on an old server (1x 4core cpu, 12GB RAM, 2x HDD SATA 1TB).
I've installed OpenMediaVault on it as a single VM.

Now after... lets say... 2 months I noticed some weired behavior in gui. Everything worked fine except missing icon in left panel VM/storage list (exclamation mark icons instead of default ones).
Now, after 2-3 days I can no longer access to PM web qui (page not found).
Funny (or not) is that VM itself still works fine. After a reboot the problem remains.
At least I can still remote access via SHH command line...

But there's more, I tried to do some troubleshooting but for example executing 'systemctl' shows:
Code: 
# systemctl
Failed to list units: Connection timed out

By the way, version:
Code: 
# pveversion
pve-manager/5.2-1/0fcd7879 (running kernel: 4.15.17-1-pve)

I wasn't doing any modifications for weeks. No updates what so ever...

Any ideas?
 
does dmesg/syslog say anything? maybe a broken disk ?

if even systemctl fails, i am not sure what can be done...
 
If you still can get to it via ssh.
As fast as you can get the all config out. Do a vm backup and get it off the machine.
I lost whole setup like this.
Depending on your hardware it can be your psu
 
I've checked ZFS status (seems fine):
Code: 
# zpool list
NAME    SIZE  ALLOC   FREE  EXPANDSZ   FRAG    CAP  DEDUP  HEALTH  ALTROOT
rpool   928G   184G   744G         -    22%    19%  1.00x  ONLINE  -

# zpool status

            sdb2    ONLINE       0     0     0

errors: No known data errors

I'm also using ZFS filesystem snapshot solution to make full/differential disk backups:

Code: 
# zfs get written
