Phil - Thank you very much for your contribution. I believe that 'gluster volume rotate <VOLNAME>' will rotate the logs on all of the servers and clients, but I have asked engineering for clarification. Your client script would almost certainly interrupt I/O, glusterfs doesn't respond well to HUP, let me get something back from engineering and I will get it out to the list and included in the next point release. The server script looks good, I would suggest a couple of changes while we get proper support added - 1. Use the 'gluster log locate' command to find the logs instead of hard coding. 2. Use 'which gluster' instead of hard coding. logrotate support should be included in Gluster, I have filed http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=2053 to get it added.

I looked at that, and I realise that this will let me rotate the logs under /var/log/glusterd/bricks and that I can call that from logrotate if I want, but how should I rotate the logs from the glusterfs clients such as nfs.log? I presume something like this would work (I've not tested it) and if so, it might be a good idea to drop a script into the RPM to avoid other people struggling with it? ---snip-- # Rotate client logs /var/log/glusterfs/*.log { sharedscripts missingok postrotate /usr/bin/killall -HUP glusterfs > /dev/null 2>&1 || true endscript } # Rotate server logs /var/log/glusterfs/bricks/*.log { sharedscripts missingok prerotate for i in `gluster volume info all | grep Volume | cut -f3 -d" "`; do /usr/bin/gluster volume rotate $i done endscript } ---snip--- Thanks Phil ps I don't use nfs in this set up, how can I stop the glusterfs daemon providing nfs service?
