Hello @theit8514

You are actually spot on ^^

I did look in my exports file which was like so :/mnt/DiskArray 192.168.0.16(rw) 192.168.0.65(rw)

I added a localhost line in case: /mnt/DiskArray 127.0.0.1(rw) 192.168.0.16(rw) 192.168.0.65(rw)

It didn’t solve the problem. I went to investigate with the mount command:

• Will mount on 192.168.0.65: mount -t nfs 192.168.0.55:/mnt/DiskArray/mystuff/ /tmp/test

• Will NOT mount on 192.168.0.55 (NAS): mount -t nfs 192.168.0.55:/mnt/DiskArray/mystuff/ /tmp/test

• Will mount on 192.168.0.55 (NAS): mount -t nfs 127.0.0.1:/mnt/DiskArray/mystuff/ /tmp/test

The mount -t nfs 192.168.0.55 is the one that the cluster does actually. So i either need to find a way for it to use 127.0.0.1 on the NAS machine, or use a hostname that might be better to resolve

EDIT:

I was acutally WAY simpler.

I just added 192.168.0.55 to my /etc/exports file. It works fine now ^^

Thanks a lot for your help@theit8514@lemmy.world !

You are completely right.

However in my mind (might be wrong here) if I use another node, i wouldn’t use the RAID array completely.

While setup up i thought that its either:

• NAS storageClass attached to the RAID array, no longhorn
• with longhorn when there is no RAID, but replication at 3

In either case, the availability of my data would be quite the same right ?

(Then there is options to backup my PV to s3 with longhorn and all that i would have to setup again though )

Thanks for your answer !
