The virtual machine failed to start

[bigface]

proxmox verson: 6.2-10
vm: centos-7

Hello!
In the process of using proxmox, suddenly a virtual machine cannot connect through SSH. After using console connection, an error is reported: Audit: Backup limit exceeded. I plan to restart the virtual machine. At this time, the problem comes. I can't restart or shut down the virtual machine through the web page. I can only shut it down by killing the virtual machine process. When the virtual machine restarts, I can only enter the system boot page:


At this time, the journalctl log information is as follows:



Try running xfs_ repair:

How can I solve this problem? Or what more information do I need to add? Hope to get help.

on what storage are the vm disks? how well is the storage? (has it any errors?) what does the host log say?

ceph status:



ceph osd tree:



ceph osd pool ls:



rbd list cephpool14:



Run the command

pvesm list cephpool14

and wait for a long time without returning the result

The virtual machine hardware info:

task history:

summary:

Moreover, the summary status under this pve often displays an error prompt: communication failure (0).

And what part of the host log do you refer to?

one of the pgs are not active since it is too full, i guess on this pg the vm stores its data

Thanks @MasterTH @dcsapak.

I found that the status of a disk is down, the disk has 500g, and then CEPH has only 200g of free space. It should be that there is not enough space left to make the data unrecoverable, and I will verify that this problem is the cause.
