I stumbled across that issue right now too. Thanks for the update and i appreciate the link to the commit.

Ok, thanks. It would be very nice to be able to do such a one-shot restore from a different datastore or to copy backups between datastores in pbs (incl. changing VMID).

Hi everyone, maybe someone can point me in the right direction. What i would like to do is to restore a VM made from one node into its datastore to a different node with its own datastore using a new VMID. Let say i have two nodes with each having its own datastore: node1 -> store1 node2 ->...

Thank you very much tcicy for this simple but yet great addition. It resolves the pain from having to type long secure passwords into the terminal during setup or login when no network is available and no spice is running. I really don't understand why this hasn't been picked up by the Devs...

Hi, what was the outcome? Regards

Read through all logs and didn't see anything special. Maybe this is beacuse of a mixed use of pve and native ceph tools?

You're right, there is not much support from Ceph but it's still possible and Ceph doesn't say "Don't do this" they just say that they don't know the multipath configuration and hence reject to do it. But in the end it's just as simple as creating the pv/vg/lv. First step would be to identify...

I have had a look at the PVE Code more precisely in Diskmanage.pm->get_disks and now it's clear that multipath devices will never show up as only whitelisted devicename patterns and special types like zfs, ceph and lvm are handled and the individual disks will show up as they match the pattern...

Well and that's actually not the case. Multipath is working fine and configured correctly. -> multipath -l mpathe mpathd mpathc mpathb mpathn mpatha mpathm mpathl mpathk mpathj mpathi mpathh mpathg mpathf But the disks section shows the individual disks only: It doesn't matter if...

In general i agree with you but throwing away FC storage systems which cost a lot is not an option. But to be honest, this has nothing to do with the setup pain. The same problems will arise with any multipath enabled system like a simple SAS Shelf with two HBAs. So IMHO we should talk about...

This makes me think that you assume the FC Storage does redundancy on its own by doing RAID. Am i right? That's not the case the FC Storage runs in JBOD Mode. So the data redundancy is done by ceph only. FC is in this context really just the transmission channel. The only added redundancy is...

Maybe it would make sense to explain why you don't recommend the usage of ceph with a direct-attached-storage using multipath.

Not really. The FC storage is directly connected to a single host through its HBAs. Multipath is for hardware redundancy (failing paths to the disks) and ceph for distributing the data across the directly attached storage of all 3 nodes. The same would happen with a SAS storage or whatever...

Hi everyone. I'm struggling with ceph using multipath and the pve provided tools. My setup is a 3 node cluster with each node having a dedicated FC storage. Each server has 2 HBAs to achieve hardware redundancy. Multipath is configured, running and the device mapper block devices are present...
