there is a known problem when storage hang as pvestatd may get stuck in
a syscall and never returns :

https://bugzilla.proxmox.com/show_bug.cgi?id=3714

if you have even ssh login problems, i guess it was some issue/hang with
the root filesystem/disks/raid

furthermore, it could have been some out of memory condition.  to get
into the details of such, it's useful
to have external system monitoring, as it will tell you when ram did
fill up slowly...

Dear All ,
We are using PVE 8.X EE , we have 8 node cluster
today one of the  cluster , we were able to login through the web
interface, but the status of the VM machines were marked as ?
We tried to login in using SSH, were able not able to  init 6 , it was
showing the message

root@pve-4:~# init 6

*Failed to set wall message, ignoring: Transport endpoint is not
connectedCall to Reboot failed: Transport endpoint is not connected*

Later on we did hard reset and the system was back
How could we know what was the problem?, which log files  should we use? to
understand the issue

Advice requested


Thanks
Joseph John
