NFS mount ownership as 4294967294 after recent patching to RHEL 6.8
Issue
- With recently applied patches, the ownership of the NAS/NFS mount on this node looks like:
root@node01 ~]# ls -l /MQHA/data
total 12
drwxr-xr-x 2 4294967294 4294967294 4096 Apr 17 2015 defs
drwxr-xr-x 2 4294967294 4294967294 4096 Apr 17 2015 utils
drwxrwsr-x 18 4294967294 4294967294 4096 Aug 17 22:20 VTA!QA!QMGR
- Expected ownership to be mqm:mqm :
drwxr-xr-x 2 mqm mqm 4096 Aug 18 23:23 defs
drwxr-xr-x 2 mqm mqm 4096 Apr 17 2015 utils
drwxrwsr-x 18 mqm mqm 4096 Aug 18 23:29 VTA!QA!OCC!QMGR
drwxrwsr-x 18 mqm mqm 4096 Aug 18 21:32 VTA!QA!QMGR
- The server having issue was recently patch to have kernel version
2.6.32-642.3.1
[root@node01 /]# uname -a
Linux node01 2.6.32-642.3.1.el6.x86_64 #1 SMP Sun Jun 26 18:16:44 EDT 2016 x86_64 x86_64 x86_64 GNU/Linux
- There is a second node server where the ownership is correct and its kernel version is
2.6.32-573.12.1
[root@node02 ~]# uname -a
Linux node02 2.6.32-573.12.1.el6.x86_64 #1 SMP Mon Nov 23 12:55:32 EST 20
- Reverting and booting off of the previous kernel version (2.6.32-573.26.1) on the node that has the issue the ownership is showing correct:
[root@node01 ~]# ls -l /MQHA/data
total 16
drwxr-xr-x 2 mqm mqm 4096 Aug 18 23:23 defs
drwxr-xr-x 2 mqm mqm 4096 Apr 17 2015 utils
drwxrwsr-x 18 mqm mqm 4096 Aug 18 23:29 VTA!QA!OCC!QMGR
drwxrwsr-x 18 mqm mqm 4096 Aug 18 21:32 VTA!QA!QMGR
- Upgrading the kernel should not impact the ownership of the NAS/NFS objects - directories files,.
The server is in the QA environment but the MQ service would not start up on the server when the ownership is incorrect.
Manually trying to change it does not help and following error is logged:
[root@node01 ~]# chown mqm:mqm /MQHA/log
chown: changing ownership of `/MQHA/log': Invalid argument
