After a power fail the server dont start properly, i can connect to the server by ssh but i don't have access to the Web UI and the virtual machines doesn't start. I could see that the /etc/pve/ directory is empty, I tried to start the pve-cluster service manually but it showme the fallowing output:

root@nodo:~# systemctl restart pve-cluster

Job for pve-cluster.service failed because the control process exited with error code.
See "systemctl status pve-cluster.service" and "journalctl -xe" for details

Then i run the suggested commands..

root@nodo:~# systemctl status pve-cluster.service

It seem a file system fail, to me in the file: config.db-wal i tried to make a backup to this file and give me an i/o error:
root@nodo:/var/lib/pve-cluster# cp config.db-wal config.db-wal.bak
cp: error reading 'config.db-wal': Input/output error

Any idea of how to solve this?, I have several vm here and many information can be lost...
Please any help would be apreciated
Thanks

an input/output error is most likely connected to a broken hard disk -> check the disk
thanks for reply, it was a bad sector, after spend some time saving all configuration that I could. When I connect a monitor to the server the first thing I saw was the server telling me that i/o error occurred because a bad sector with the sector number... I prepare flash drive with HirenBootCD and repair the bad sector in a couple of minutes... restart and all ok now
