Scenario:
2 SP nodes AIX 4.3.3, PSSP 3.4, HACMP 4.4.0 (PSSP upgrade completed
this past weekend)
SSA disk attached to system 1
10 filesystems on SSA disk mounted under name 1-10
10 filesystems named 1-10 NFS mounted on same system 1 as filesystems
11-20
10 filesystems named 1010 NFS mounted on system 2 as filesystems 11-20
Problem:
When a job runs, the NFS mounts on system 1 hang up (you can't "ls"),
the application dies,
The NFS mounts on system 2 are fine.
The SSA mounts on system 1 are fine.
The offending job gets no CPU time.
There is much network activity on the NFS segment (private tokenring
segment between the 2 servers - and 2 others)
Question:
What is going on ? Why does this job bury the NFS mounts ?
Did the PSSP upgrade break something ?
Is there a known NFS cross-mount issue I may be seeing ?
Background:
smitty | clverify: Checks out OK
Patch level: ML10
NFS Client: 4.3.3.81
NFS Server: 4.3.3.11
I've run traces and everything and I'm pretty stumped so far.
