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

[Abe Shelton]

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.
