[Gluster-users] NFS expose subfolders only

[Thai. Ngo Bao]

Anush, thanks for the quick reply.

Below is the output of showmount at server side:

[root at GS_BackupFarm_Cluster01 ~]# showmount -e localhost
Export list for localhost:
/bkfarm/00 *

Output from netstat:

[root at GS_BackupFarm_Cluster01 ~]# netstat -vtlpn

---------client side ---------------
[root at GSO_DB_Local1 ~]# showmount -e localhost
mount clntudp_create: RPC: Program not registered
[root at GSO_DB_Local1 ~]# mount -o vers=3 bkf3:/00 /bkfarm/
mount: bkf3:/00 failed, reason given by server: No such file or directory

Any ideas?

Thanks,

Hi,

Please make sure that nfs-kernel-server isn't running.

Can you pase your showmount -e output?

The right way to mount Gluster NFS is,
mount -o vers=3 bkf3:/00 /bkfarm/

Hi,

I have tried the trick several times but had no success so far.

Below is the info of my testing environment

[root at GS_BackupFarm_Cluster01 ~]# gluster volume set bkfarm nfs.export-dir /00
Set volume successful
[root at GS_BackupFarm_Cluster01 ~]# gluster volume set bkfarm nfs.export-volumes off
Set volume successful
[root at GS_BackupFarm_Cluster01 ~]# gluster volume info

Volume Name: bkfarm
Type: Distributed-Replicate
Status: Started
Number of Bricks: 4 x 2 = 8
Transport-type: tcp
Bricks:
Brick1: bkf1:/sfarm
Brick2: bkf2:/sfarm
Brick3: bkf3:/sfarm
Brick4: bkf4:/sfarm
Brick5: bkf5:/sfarm
Brick6: bkf6:/sfarm
Brick7: bkf7:/sfarm
Brick8: bkf8:/sfarm
Options Reconfigured:
nfs.disable: Off
nfs.export-dir: /00
nfs.export-volumes: off
diagnostics.client-log-level: ERROR
diagnostics.brick-log-level: ERROR
cluster.min-free-disk: 10%
performance.cache-size: 2048MB

----------client side ---------
[root at GSO_DB_Local1 ~]# mount -t nfs bkf3:/00 /bkfarm/
mount: bkf3:/00 failed, reason given by server: No such file or directory

What am I missing? Any thought?

Thanks,
~Thai

Hi,

These volume set options should do the trick

gluster volume set xfsvol nfs.export-dir /subdir

 gluster volume set xfsvol nfs.export-volumes off

Let me know.

Hi,

AFAIK one can expose subfolders thru gluster NFS for a client if he/she has option nfs.export-volumes ON and nfs.export-dir Enable. There will be a case (for security purpose)  when people just want to expose only subfolders for clients thru NFS.  I wonder if it is possible to expose only subfolders thru gluster NFS protocol for a client?

Any insight into this is much appreciated.

Thanks,
~Thai
