OCFS2_is_the Best
on ubuntu LTS while doing a test for cluster enviroment I get some errors when I use ls -l /mymount/local/ . Sometimes I get 'Segmentation Fault'
or 'uninterruptible sleep' as show from ps
'2361 pts/1 D+ 0:00 \_ ls -l /opt/local/'
D uninterruptible sleep (usually IO)
here my answer to "Zhen Ren" <zren@suse.com>
I follow your hint and use suse ;D
for new test environment linux-B64 and linux-B64:~
# cat /proc/version

here just simples test where the filesystem ocfs2 work well :P
