Grey Question Marks on PVE, VM's and Storage

[mablower]

6.4 Proxmox, recently went from 5.4 to 6.4, about two weeks ago. Fresh install of 6.4 and restored VM's.

Yesterday I got the grey question marks on PVE, VM's and storage. VM's still functioned but SSH was only way I could manage PROXMOX.

Tried the stop start of services on this thread.
https://forum.proxmox.com/threads/p...on-all-machines-and-storage.81087/post-364014

Eventually web interface was totally dysfunctional and a hard restart of the computer Proxmox was needed to restore normal functions. Successful, But...

What do I look for to prevent this from happening again in another two weeks ?

I don't know how to find cause. Any help would be much appreciated.

Feedback from my.proxmox.com support ticket indicates that issues are related running a mix of PVE 6.3 and PVE 6.4, which requires and updating the install. I installed from early 6.4 iso and needed to update right away.

proxmox-ve: 6.3-1 (running kernel: 5.4.106-1-pve)
pve-manager: 6.4-4 (running version: 6.4-4/337d6701)

And after check for and installing any BIOS updates, I also need to install/update to latest Microcode. Link to Debian Microcode information.

I also have an issue with drive 03 in my 8 2TB disk raid 10 configured storage. Following two lines came from syslog for the day of my issues. Last line is comment is from tech support ticket response by PROXMOX tech..

Aug 7 01:59:51 pve smartd[1021]: Device: /dev/bus/0 [megaraid_disk_03] [SAT], 1 Currently unreadable (pending) sectors
Aug 7 01:59:51 pve smartd[1021]: Device: /dev/bus/0 [megaraid_disk_03] [SAT], 7 Offline uncorrectable sectors
This indicates an issue with one of your disks. This could influence `pvestatd` and in turn lead to question marks being shown.

Its been recomended that I move foward onto 7.X as 6.4 has reached EOL as of July 2022.
