HA migrations failing (exit code: 255). Likely NFS share issue.

[wintertims]

Hello,

Recently I've renamed and modified the file path of an NFS share on my FreeNAS that my 4 hosts look at for ISO's. Recently, two of the VM's on one host migrated to another and are having an issue migrating back to the original host. I want to believe this is because of the NFS modifications. The host tries to migrate back to the original host every 10 seconds, but aborts every time. I've also tried unlocking and migrating the VM's manually, but I ran into issues. I've also tried seeing if there were some lines I could modify in /etc/fstab, but I couldn't find the NFS path/target in there.

I have tried to edit the original NFS share on the storage tab in the PVE GUI, but I am not able to modify the `Export` property of the NFS share. I've also added a new NFS share in the mean time that has the new file path to the NFS share.

Should I delete the NFS share with the old and invalid path/target? Let me know what you think.

The renamed share has the same content, or?
Simplest thing then would be to delete the one with the invalid path and recreate it with the same name and updated exports.

Alternatively, you can also edit /etc/pve/storage.cfg, that's where Proxmox VEs storage definitions are saved. There you could just change the export path directly.
