[SOLVED] NFS Volumes not mounting on boot

custangro · 07-02-2009, 02:48 PM

Hello,

I have added some NFS volumes in my /etc/fstab; but these volumes do not mount on boot...Here is my fstab

Code:

root@host# cat /etc/fstab
/dev/vg0/lvm_root       /                       ext3    defaults        1 1
/dev/vg1/lvm_data       /data                   ext3    defaults        1 2
/dev/vg0/lvm_usr        /usr                    ext3    defaults        1 2
LABEL=/boot             /boot                   ext3    defaults        1 2
tmpfs                   /dev/shm                tmpfs   defaults        0 0
devpts                  /dev/pts                devpts  gid=5,mode=620  0 0
sysfs                   /sys                    sysfs   defaults        0 0
proc                    /proc                   proc    defaults        0 0
/dev/vg0/lvm_swap       swap                    swap    defaults        0 0
# NFS Mounts
netapp-nfs:/vol/staging/panda   /data/panda     nfs     defaults        0 0
netapp-nfs:/vol/uploads/panda   /data/uploads   nfs     defaults        0 0
netapp-nfs:/vol/production/cvsroot      /data/cvsroot   nfs     defaults        0 0

The only NFS volume that mounts is /data/cvsroot but the other 2 don't. As soon as the server is up and running I do a

root@host# mount -a

And this mounts the ones that didn't mount on boot. I looked through dmesg and didn't find anything...

Code:

root@host# dmesg | grep -i nfs
root@host#  dmesg | grep -i mount
Mount-cache hash table entries: 512
EXT3-fs: mounted filesystem with ordered data mode.
EXT3-fs: mounted filesystem with ordered data mode.
EXT3-fs: mounted filesystem with ordered data mode.
EXT3-fs: mounted filesystem with ordered data mode.
root@host#  dmesg | grep -i netfs

Also /var/log/messages shows the same...

I already contacted Red Hat support and they have (yet) to contact me with anything yet. Anyone experienced the same problem?

Running: RHEL 5.3

Are you sure any NFS mount is successful after you boot the machine as your grep nfs returns nothing and grep mount only returns ext3 fs...

The last time we faced a similar issue, it was down to a network. The network was not ready when the mount occurs so all our NFS mounts failed...
Maybe worth checking the network...

If worse comes to worst, you can always add a line in /etc/rc.local

Even I recommend the same, you can do this until you find a solution to your problem. Needless to say, it will work smoothly.

Yeah, in the meantime I have added "mount -a" in the /etc/rc.local file...

I will post what I find...

So here is what Dell/Red Hat said...

It's a "timing" issue (like I guess we all thought)...Dell/Red Hat recomends doing this...

Code:

root@host# cd /etc/rc3.d
root@host# rm S25netfs
root@host# ln -s /etc/init.d/netfs S98netfs

I did this and it worked!

Also I edited the /etc/init.d/netfs chkconfig line to match the "98" startup.

Thanks Custangro, for posting the solutions for learners like me to have more knowledge.

What does 25 means in S25netfs, and 98 in S98netfs ?
And how do they came to know, that this should be 98 and not any other number.

And, did you modified this line in /etc/init.d/netfs as

Code:

chkconfig: 345 25 75 98

It was Dell support...they only offered the solution...not an explanation (go figure)

Also, another "trick" is to put a mount -a in your /etc/rc.local file.
