These are all on 3.4.2 with Ubuntu 13.10.

 This rings a bell...
 
 I mapped a remote nfs share to one of my nodes and mapped the local nfs
 share, to the local gluster volume as well and started to copy (with cp)
 files from one mount to the other.
 
 Somewhere down the line all stalled, the server was irresponsive, even
 restarting glusterd solved nothing. Had to reboot the nodes.
 
 CentOS 6.5 and Gluster 3.4.2.
 
 Since then,  I haven't tried those copies, but, I also, I am now using the
 native glusterfs client just in case.

 I have not seen that with the fuse client.  I had it happen repeatedly
 when we were using gluster/NFS for /var/lib/nova/instances and/or
 /var/lib/nova/instances/_base.  The access to instances-XX/disk
 (or its qcow2 backing image) would hang completely or be very slow
 under heavy load.  The VM interprets the delay as a problem on
 /dev/vda and remounts RO.

 Has anyone encountered this before? Gluster version is 3.4.2

[Gluster-users] Openstack Havana Gluster /var/lib/instances issues

2014-03-18 Thread Aydelott, Ryan M.
I was wondering if anyone had seen similar issues before, when booting a vm 
with a root volume on local disk things work fine. 

When I try to do the same with /var/lib/nova/instances mounted via gluster/fuse 
I get the following: http://paste.ubuntu.com/7116594/

I have of course insured perms were correct with chown -R nova:nova 
/var/lib/nova/instances, additionally app armor is completely 
unloaded/disabled. 

Has anyone encountered this before? Gluster version is 3.4.2
