Storage question

[Thomas15]

Hello,

I have a question regarding the best approach do add a shared storage to a Proxmox Cluster. I have a storage avaliable in network trough ISCSI. It was formatted with XFS and made avaliable on the first node as mount point /vz. Now a second node is supposed to join the cluster. The idea is to also mount that same ISCSI target on the second node as a directory storage in /vz as well. When marking both /vz mountpoints as shared in Proxmox I assumed that Proxmox knows that the content of /vz on every node is identical. But it seems I´m wrong here. What I´m doing here is probably not the correct way?

Thanks for any help in advance!

Yes, you cannot do that, because XFS is not a cluster filesystem and can only be mounted on one node.

Please see here for all possible solutions. Your best fit without much change would be to use LVM on iSCSI.

Thank you for your fast help. For now I need to find a way to get the current running machines off the ISCSI target to another storage so that I can reconfigure the storage accordingly.

Just move it via the Hardware Tab: Select your disk and move it to another storage.

Yes thank you, I will do that. I could get a new ISCSI target with same space so I can set up the new and just move the disks from the old. Afterwards I can delete the old one.
