I have 2 nodes as HA cluster (use heartbeat) with resource httpd, nginx (both nodes) and mysql(node1). When i reboot node1, on node2 glusterfsd process get 100% processor's time (by "top" output), and /mnt/cluster is unreadable (when i try read it, my console don't answer). And node1 after reboot can't read /mnt/cluster until node2 will be rebooted.
Sometimes reboot is OK. Also this situation can appear when some files delete by node1.
If i reboot node2, all correct, if i move mysql to node2, both nodes reboot ok.

I can't found 2.0 series glusterfs in Fedora 9 repository :(

I found about my problem in "[Gluster-devel] Effect of AFR's known file re-open issue on MySQL"
http://www.mail-archive.com/gluster-devel@nongnu.org/msg05669.html

I think i must use drbd for my database data?

Can you try compiling 2.0 release from sources?

Here
http://www.mail-archive.com/gluster-devel@nongnu.org/msg05669.html

a read this:
"File re-open support will be available in 2.0.1 (say another month)"

Do you think my problem is solved in 2.0.0rc6? And my principe - not using unstable version for productive.

PS: i localised my problem - it is rerun mysql server. If i do /etc/init.d/mysqld restart 2-3 times on node2 (with stopped heartbeat on both nodes), glusterfsd is block all glusterfs dev and get 100% processor time.
