Issue with multiple NFS storage mounts on the same server

[AraToken]

Hi!

i am currently a bit lost while trying to get a storage running. In my current setup i am trying to add two NFS storages to my cluster that both reside on the same server runnign with DRBD.

The storage.cfg is definetely correct pointing to the right exports:
Stor1 - export /mnt/drbd0
Stor2 - export /mnt/drbd1

For some reason proxmox has issues while mounting the second storage and i am not sure why. It either tries to mount both as drbd0 or drbd1 but never one as 0 and the other one as 1 as it should be.

Is there perhaps a known issue when trying to use the same server source IP for multiple different nfs storages? If so: am i required to configure a second IP for my drbd1 storage even when it lies on the same server?

Thank you in advance!

Hey,

can you try mounting them manually with mount -v -t nfs ... and post the output? Could you also post exportfs -v from the server? Using the same IP for multiple NFS exports is usually not a problem.

Hi,

i tried using a different IP for the second mount but the same issue is present. For some reason according to df -h is the storage even mounted multiple times with the same size which stor2 should be. (the first one is supposed to be around 8 TB)

10.10.10.222:/mnt/drbd1   12T     0   12T   0% /mnt/pve/STOR2
10.10.10.222:/mnt/drbd1   12T     0   12T   0% /mnt/pve/STOR1
10.10.10.223:/mnt/drbd1   12T     0   12T   0% /mnt/pve/STOR2

Mounting the storage manually does work as expected so i assume it has to do something with Proxmox. Sadly i cannot provide output for exportfs -v because the command does not exist.

We used nfs storage with drbd before on the same cluster so i am confused why it does not work now. Only difference was here that we only had 1 mount instead of 2.
