File system not mounting at bootup
Hi,

I've got a recent problem with 2 file systems on an AIX 5.3 server. The fs's are marked to auto mount at startup and do show as being mounted after a a restart however if you cd to the mount point and 'df -g .' it shows the fs hasn't actually mounted.

Code:
$ mount |grep SQLT0001.0
         /dev/stpfadb03   /db2data/db2afaa1/stpfaad1/data/db2afaa1/NODE0000/SQL00001/SQLT0001.0 jfs2   Jul 31 13:05 rw,log=/dev/loglv01
         /dev/stpmbdb04   /db2data/db2amba1/stpmbadr/data/db2amba1/NODE0000/SQL00001/SQLT0001.0 jfs2   Jul 31 13:05 rw,log=/dev/loglv01
         /dev/stpdbdb04   /db2data/db2adba1/stpdbad1/data/db2adba1/NODE0000/SQL00001/SQLT0001.0 jfs2   Jul 31 13:05 rw,log=/dev/loglv01
         /dev/stpdbdb09   /db2data/db2adbb1/stpdbad1/data/db2adbb1/NODE0000/SQL00001/SQLT0001.0 jfs2   Jul 31 13:05 rw,log=/dev/loglv01
$ cd /db2data/db2amba1/stpmbadr/data/db2amba1/NODE0000/SQL00001/SQLT0001.0
/db2data/db2amba1/stpmbadr/data/db2amba1/NODE0000/SQL00001/SQLT0001.0 $ df -g .
Filesystem    GB blocks      Free %Used    Iused %Iused Mounted on
/dev/stpmbdb02      1.00      0.97    3%      307     1% /db2data/db2amba1/stpmbadr/data
$

If I try and mount this fs I get the message 'The requested resource is busy', so I have to unmount it and then mount it and it mounts correctly.

Code:
$ ls -l /db2data/db2amba1/stpmbadr/data/db2amba1/NODE0000/SQL00001/SQLT0001.0
total 0
$ unmount /db2data/db2amba1/stpmbadr/data/db2amba1/NODE0000/SQL00001/SQLT0001.0
$ mount /db2data/db2amba1/stpmbadr/data/db2amba1/NODE0000/SQL00001/SQLT0001.0
$ ls -l /db2data/db2amba1/stpmbadr/data/db2amba1/NODE0000/SQL00001/SQLT0001.0
total 8
-rw-------   1 db2amba1 stpaadm         512 Jul 31 00:18 SQLTAG.NAM
$

Anyone got any ideas what could be causing this?

Thanks

Gareth

LEARN ABOUT FREEBSD

msdos

MSDOSFS(5)						      BSD File Formats Manual							MSDOSFS(5)

NAME

     msdosfs -- MS-DOS file system

SYNOPSIS

     options MSDOSFS

DESCRIPTION

     The msdosfs driver will permit the FreeBSD kernel to read and write MS-DOS based file systems.

     The most common usage follows:

	   mount -t msdosfs /dev/ada0sN /mnt

     where N is the partition number and /mnt is a mount point.  Some users tend to create a /dos directory for msdosfs mount points.  This helps
     to keep better track of the file system, and make it more easily accessible.

     It is possible to define an entry in /etc/fstab that looks similar to:

     /dev/ada0sN	     /dos    msdosfs	     rw      0	     0

     This will mount an MS-DOS based partition at the /dos mount point during system boot.  Using /mnt as a permanent mount point is not advised
     as its intention has always been to be a temporary mount point for floppy and ZIP disks.  See hier(7) for more information on FreeBSD direc-
     tory layout.
