Red Hat Bugzilla – Bug 80081
clurmtabd doesn't sync export subdirectories
Last modified: 2008-05-01 11:38:04 EDT
Description of problem: If a service is specified with a given NFS export: /export and an authorized client mounts: /export/dir1 then the /var/lib/nfs/rmtab entry: client:/export/dir1:0x00000001 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.
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!
Wrong status field; hours updated.
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. Thanks!
