[DRBD-user] DRBD on top of ZFS?

hello, I've been using zfs on linux for some time and it seems really stable. I was wondering if zfs could be a better option than lvm as a backing device for drbd (zvols). Is zfs on linux a supported option from drbd side or not yet? thank you ___

Hello, Quick question. I noticed the following command in Linstor: 'linstor node interface modify' By using this command someone can modify the network interface/ip address that Linstor is listening on. Let's assume that we have already created a 3 node DRBD/Linstor cluster in the ip range

[DRBD-user] Linstor | Peer's disk size too small

Hello, Trying to create a new resource by using Linstor, on a 3 node cluster. Two of the nodes are using LVM thin as storage backend and one of them is using ZFS. I created a test RD, then a VD with a size of 10GB. Then, I create the resource on the LVM backed nodes by using 'linstor r c test'

I have created a snapshot for a VM by using Proxmox web interface, by using the previous version of linstor-proxmox plugin (2.8-1). Today, I upgraded to version 2.9.0-1 , not sure if this problem is affecting this version as well. When trying to restore the snapshot from the command line to a new
