Hi,

please update your system and check again after you restart the server.

I tried restart services and it's ok. But what's the root cause lead to this?

 

[wolfgang]

Your problem is you can't start it because you have "Too many open files"
Do you use containers on this system?
Try to increase the file limit.

No, after this problem i have stopped all LXC and migrate to KVM only.

 

[wolfgang]

Do you use extra software on the host what open may files?
Like samba?

Hello,

We use this for hosting VPS only.

All these node connect to CEPH storage (for VM disk) and NFS v3 (for backup) only.

Our backup server got problem with raid array and it timeout (service pvestatd status) in the past few days. Now it’s up after rebuilding raid array.

We will monitor again.

Honestly something strange with this cluster. I have setup 5 cluster and only this cluster has problems. (Eg: migration VM and stuck at ssh key, remove know_hosts then it ok but another host got problem. This is already mentioned in this thread)
