Did anyone tryed to use zfs encryption? I have installed test environment (zfs raid 10 with 4 HDD), then created encrypted dataset.
zfs create -s -V 104857600k -o encryption=on -o keylocation=prompt -o keyformat=passphrase rpool/data/vm-100-disk-0
Then rebooted server and system wont boot...
But you can simply make zfs clone on this snapshot and then copy data from this clone to new zvol (as you do when we cloning with "current" option). After that - destroy this zfs clone zvol.
Is this a problem?

username admin

pool rbd
When I built this cluster, I have the same problem, but it was my mistake with keyring file...

Or you can manually edit host config file in /etc/pve/qemu-server
May be this is some pmxcfs issue, see syslog messages about corosync and so on. https://pve.proxmox.com/wiki/Proxmox_Cluster_file_system_(pmxcfs)
Try to enable debugging, if no errors.
I have this problem, when remove A-records for nodes from our dns server.
Solution was - making an entry for every node in /etc/hosts. Or configure your dns.
Then reboot problem node
Could anyone tell me, what this parameter mean?

I have USB modem (Huawei E3372h), connected to host. On host it works well, shows 30/30 megabits on upload and download.
When I map it to linux VM (virtual router), its upload speed dramatically goes down - only 1 megabit on upload. But download is Ok - same 30 megabit, as on host.
