I have created the tarballs, you can find them at
http://www.kfki.hu/~kadlec/gfs/:
- Kernel is vanilla 2.6.27.21, the '.config' file is preserved in the
tarball as 'config'.
- On top of that I installed vanilla e1000-8.0.6, e1000e-0.5.8.2 and
aoe6-69. The same e1000-8.0.6 and e1000e-0.5.8.2 are used with the
working cluster-2.01.00 to which the earlier aoe6-59 was added.
- The cluster-2.03.11 is also the vanilla version, except that since
this thread started I have added two small corrections:
- fence/fenced/agent.c fixed, see
https://www.redhat.com/archives/linux-cluster/2009-March/msg00222.html
- gfs2/mount/umount.gfs2.c, '-l' flag support added, see
https://www.redhat.com/archives/cluster-devel/2009-April/msg00000.html
The configure options are in 'configure-options', the locally used init
scripts can be found under deb/DEBIAN/etc ;-)
The GFS volumes are mounted with noatime, quota is enabled (can't leave
that off). The volumes are tuned with the values:
statfs_slots 128
statfs_fast 1
demote_secs 30
glock_purge 50
scand_secs 3
Those are mostly remnants of the time when Maildir was in use instead
of plain mailbox format and we tried to cure the terrible performance.
Probably it's worth to note that 'statfs_fast 1' takes a lot of time to
complete (usually around 15-20 seconds) which is, at least for me,
surprising.
I think that's all.
Best regards,
Jozsef
