Hi,
The management node is SL 6.6. /install is a local disk partition and
NOT mounted from another server. After the initial upgrade, xcatd was
restarted and it disregarded the /install entry already in present in
fstab. It tried to remount itself on to /install and caused hangs when
/install was accessed. This was also causing issues on reboot and we
had to go into single user mode and mount systems manually as xcatd
still tried to make the mount even though the erroneous fstab line was
removed. This resulting in the mount error provided below. Hope this
helps. Thanks.

Hi Will,
I want to confirm the following information:
1, Does the xcat management node OS is SL 6.6 ?
2, Do you use the mounted /install directory from other server?
3, After xCAT 2.10 upgrade to xCAT 2.12, is xcatd stopped?
4, When you start xcatd, you hit the new issue ?
*service xcatd start*

Sure. We are running SL 6.6. The issue with makedhcp happens every
time we run it. The commands appear to work without error, but the
leases file is never modified and entries have to be manually added or
removed. Unfortunately, I was not the one who upgraded to 2.10, so I
cannot say when this behavior started exactly. I do know that it
worked prior to 2.10.
As for the mount, it definitely started after I upgraded to 2.12. I
read in the documentation that this is the default behavior. However,
it was not immediately evident how to disable it. To reproduce, we
simply have to start xCAT (we are transitioning to OL7, so the image
errors are OK):
*service xcatd start*
Starting xcatd mount.nfs: access denied by server while mounting
XXX.XXX.XXX.XXX:/install
Error mount -o rw,nolock XXX.XXX.XXX.XXX:/install /install
Error: Cannot find the OS image SL-x86_64-install-pvfs on the osimage

Error: Cannot find the OS image SL-x86_64-install-service on the
osimage table.
Error: Cannot find the OS image ol7-x86_64-install-service on the
osimage table.

This is also causing some issues during reboots as it appears that it
wants to still mount atop itself.
/install is already mounted, as this is our MN:
*df -h /install*
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg00-install
1.0T 35G 989G 4% /install
Let me know if you need any more info. Many thanks.

We are running xCAT version 2.12. It was recently 2.10. I
upgraded
thinking that this would resolve an issue with makedhcp not
updating
dhcpd.leases. Not only did it not resolve the issue, but it
caused an
additional one in that xCAT now wants to mount /install atop
of itself
puon start-up when it is a separate partition on the disk. I
did look
through the documentation with little success. Any help would be
appreciated. Thanks.
