I no longer detected any stability problems (have been in production for about a year).
However, I no longer did live motion tests under very heavy load (that was the crash condition).
Hi Dominik,

Hello,
I'm trying to use a ZFS backed DRBD storage on Proxmox 5.1
Everything is working fine and integration is great but I'm facing some serious stability issues under heavy write load.
Basically under heavy write load a node crashes especially (but not only) during VM live migration.
