[Gluster-devel] Gluster 3.3 / Stripe+Replicat / Healing+Locking on VM's

[Gareth Bult]

Hi, 

I was under the impression that under Gluster 3.3 the self-heal process would only lock parts of files as required 
during the self-heal process ?? 

I have a 3.3 setup running here and earlier rebooted one of the storage nodes. Replication meant that the volume 
holding around 20 VM's (400G's) kept on running quite happily. However, when Gluster restarted and kicked off 
it's self heal, it queued and LOCKED all 20 VM's, unlocking images as the healing process finished on each one, 
over a period of a number of hours (!) 

I'm using 3.3.0 release from the semiosis PPA on Ubuntu 12.04. 

Is there a trick to making this work properly, or is there a fix due out that will correct this behaviour ??
