Description Lon Hohberger 2002-12-19 13:34:46 EST
Description of problem:
If a service is specified with a given NFS export:


and an authorized client mounts:


then the /var/lib/nfs/rmtab entry:


does not get synchronized across the cluster, causing ESTALE in the event of
fail-over or manual relocation.

Version-Release:    1.0.16-7
How reproducible:   Always

Steps to Reproduce:
1. Create a clumanager service with an NFS export "/export", available to world
(*) with any mount options.
2. Create a directory "/export/dir1"
3. Mount the NFS mount "/export/dir1" on any authorized client.
4. Power-cycle the active cluster server.
Actual results:
Client which has /export/dir1 mounted receives ESTALE, even if it also has
/export mounted (for which, it does NOT receive ESTALE!).

Expected results:
Seamless transition.

Have a fix for this and memory consumption.  Ironing out bugs.
Comment 2 Lon Hohberger 2002-12-20 11:40:05 EST
Testing mostly done.  The build has these features:

- Performance an order of magnitude faster (was testing merges/reads/syncs on
your 13K-line file plus my 4K-line file).
- Memory consumption (while using just the 13K-line file) is about 10% of what
it was.
- Subdirectories sync properly.

Fix in pool.  Test away!
Comment 4 Lon Hohberger 2002-12-20 14:36:57 EST
Wrong status field; hours updated.
Comment 5 Jim Strong 2002-12-23 11:38:39 EST
We have been running with clumanager-1.0.19-1suny.i386.rpm in place for about 60
hours now, 4 NFS servers, 2000 clients, active/active with multiple exports per
service, and this seems to work fine at this point.  Service start/stop/relocate
is fast, and no ESTALE on server failure or manual service relocate.
