hi,

2 days ago we had a hardware problem with our backup server.
it is connected to proxmox with nfs share for all backups and installation images. also 3 virt machines have some backup disks shared

so in the last hours after the crash some virtual machines also suddently became unresponsive. the graph says some 40p off hdd which is impossible and then cpu hangs at 100% and it is impossible to access it via vnc...
it just happend to 5 virtual machines...(and only windows) some virtual machines which had a virtual disk which is on the nfs share did still work.

i cheched all logs and found nothing.
is there a way to increase logging? specially kvm related stuff.... its soo hard to find the reasons..

best regards
philipp
