Shawn,
I have been seeing the same thing on one of my clusters (shown
below) under Red Hat 4.6. I found some details on this under an article
on the open-shared root web site
(http://www.open-sharedroot.org/faq/troubleshooting-guide/file-systems/gfs/file-system-full)
and an article in Red Hat's knowledge base
(http://kbase.redhat.com/faq/FAQ_78_10697.shtm). It seems to be a bug in
the reclaim of metadata blocks when an inode is released. I saw a patch
(bz298931) released for this in the 2.99.10 cluster release notes but it
was reverted (bz298931) a few days after it was submitted. The only
suggestion that I have gotten back from Red Hat is to shutdown the app
so the GFS drives are not being accessed and then run the "gfs_tool
reclaim <mount point>" command.

Does GFS reserve blocks for the superuser, a la ext3's "Reserved block
count"? I've had a ~1.1TB FS report that it's full with df reporting
~100GB remaining.
