[Linux-cluster] What is the status of GFS?

[Vincent Aniello]

What is the current recommended stable version of the Linux kernel and
GFS combination?

I recently setup GFS 6.0.0-15 with kernel version 2.4.21-20.ELsmp.
According to the message below, though, this will not give me the best
performance and stability.  Should I upgrade to a later kernel?

Will the new version of GFS run with the 2.4 kernel or will it require
2.6?

I've been lurking too and am also very interested hearing the official, 
up-to-date status of gfs on both RHEL3 and FC3.

We've managed to get GFS-6.0.0-15 working on RHEL3U3 with directly 
attached SAN storage. (3 nodes, shared disk array via FC HBAs, each node

running lock_gulmd)

In my first round of benchmarks using bonnie++ on kernel 
2.4.21-20.ELsmp, the 'many small files' tests didn't work out so well.

We're retesting now with kernel 2.4.21-25.ELsmp. So far everything seems

stable and FS performance compared to stock ext3 seems decent.

- with bonnie++ running simultaneously on each machine, ext3 averages 
77.10 MB/sec writing and 54.65 MB/sec reading.
- same setup/methodology with gfs manages 63.01 MB/sec avg for writing 
and 54.87 MB/sec avg for reading.
