[SOLVED] TS-412 exporting multiple NFS version

[toons]

Hit a wall with this one, cant seem to get around it

QNAP Version: 4.3

Issue

I have multiple NFS exports, all running from /share/md0_data, here is the output of /etc/exports

Code: Select all

"/share/MD0_DATA/TV" *(rw,async,no_subtree_check,insecure,no_root_squash)
"/share/NFSv=4/TV" *(rw,nohide,async,no_subtree_check,insecure,no_root_squash)
"/share/MD0_DATA/backups" *(rw,async,no_subtree_check,insecure,no_root_squash)
"/share/NFSv=4/backups" *(rw,nohide,async,no_subtree_check,insecure,no_root_squash)

TV , on a Debian 9 Stretch client mounts with NFS v3
Backups, on the same Debian 9 Stretch client, mounts with nfs v4

The /etc/fstab entries on the debian filesystem are identical

Code: Select all

192.168.1.91:tv /media/tv nfs user,exec,suid,dev,rw,nofail 0 0
192.168.1.91:backups /media/backups nfs user,exec,suid,dev,rw,nofail 0 0

But, when they are mounted using 'mount' tvseries

Code: Select all

192.168.1.91:/backups on /media/backups type nfs4 (rw,relatime,vers=4.1,rsize=32768,wsize=32768,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=192.168.1.2,local_lock=none,addr=192.168.1.91)

192.168.1.91:tv on /media/tvseries type nfs (rw,relatime,vers=3,rsize=32768,wsize=32768,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=192.168.1.91,mountvers=3,mountport=30000,mountproto=udp,local_lock=none,addr=192.168.1.91,user=toons)

Wow, so case sensitivity plays a part here?? The hell?

mounting the 'tv' mount above, with the proper 'case' (.e.g, TV) results in NFS v4 as expected.
Sigh

Amazing the NFS client does locate and mount the non-case matching export at all.
