Description
I updated a Lustre installation from Lustre 2.1.6 to 2.5.2. Now something seems to be wrong with the llogs. After doing writeconf on all targets I can mount a client once, but after unmounting the client again, all subsequent tries to mount clients result in errors like this:
2014-07-31T12:57:12.198389+02:00 l3mds1 <kern.err> kernel:LustreError: 68983:0:(obd_mount.c:1323:lustre_fill_super()) Unable to mount (-5)
2014-07-31T12:57:13.198412+02:00 l3mds1 <kern.err> kernel:LustreError: 15c-8: MGC10.3.6.21@o2ib: The configuration from log 'lustre3-client' failed (-5). This may be the result of communication errors between this node and the MGS, a bad configuration, or other errors. See the syslog for more information.
2014-07-31T12:57:13.198428+02:00 l3mds1 <kern.err> kernel:LustreError: 69606:0:(llite_lib.c:1046:ll_fill_super()) Unable to process log: -5
Can the client logs be brought back into a consistent state? Is writeconf not supposed to fix any llogs issues?
