ls.

i've got /s01 and /s01/app which are both gpsf filesystems.
the automount option is YES but for some reason always /s01/app mounts
first and afterward /s01 ergo no /s01/app!!!

how can i change the mount order so gpfs is first mounting /s01 and
afterwards /s01/app?

1)
Check your /etc/filesystem on EACH node . Is the mount order correct on
all cluster nodes ?

2)
Check with
$ mmlsmgr
the system manager for a FS.

Its bad if node A mounts /s01 and node B mounts /s01/app

3)
Maybe you are runing in a timing issue. Meaning that /s01/app will be
mounted before /s01 - i do not know if GPFS 2.x ( x=>2) can asyncronly
mount.

4)
Do not use nested GPFS mount when possible. Just create a Subdirectory
for GPFS mounts like:

/cls

and mount there all GPFS FS

5)
Do not use automatic mount at all.

Hajo,

tkx
but
1)
i've checked /etc/filesystems and /s01/app follows /s01 on both nodes.

2)
for all gpfs filesystems on node is the manager

3)
yeah that's the question.....
how can i change the mount order so that /s01 wil mount before /s01/app

4), 5)
yes i could do that

Check ( from GPFS 2.1 )
$ /var/mmfs/gen/automountFile
it should contains the order of mounting the Filesystems:
and
$ automount.scr
