Greetings,
We've got a two-node cluster running RHEL 5.1 that we've been
experimenting with and have discovered a problem with gfs2. As part of
our build environment, we have some find scripts that walk a directory tree:
#! /bin/sh
for html in `/usr/bin/find curGenerated -name \*.html -print` ; do \
cat $html > tmpCR.html ; \
/bin/mv tmpCR.html $html ; \
done
The curGenerated directory has about 141 subdirectories, each of which
has from 2-10 subdirectories. What we find is that this find script
will hang the operating system when it is executed within a gfs2
partition that is shared between the two nodes. Fencing is configured
and detects the hung node and restarts it, but that's not much of a
consolation. The gfs2 partition lives on a fibreChannel array (HP
EVA5000), and quotas are not turned on. The gfs2 filesystem continues
to operate normally on the other node.
Is this a known bug in gfs2? Is there something we could do to help
find this problem?
Thanks!
