[Gluster-users] 3.6.1 and openstack

Tue Jan 27 11:43:17 UTC 2015

Hi Xavi,what happens is that Nova cannot create the file structure which is needed in order to create the virtual machine.In /var/lib/nova/instances, I can find only one directory under a casual name (random), for example ca095fd4-1c0c-4fb4-a2d8-a0d7586c0ffa. If I try to list the content, the command fails and never comes back. The shell freezes.By the way, I try to find out some more verbous logs and to update the spftware to 3.6.2. In this case, should I unistall 3.6.1. and install it again?

 Hi Pedro,

do you get any specific error ?

 From logs, the only thing I see is a warning about a GFID not being 
available. This can cause troubles, but I'm not sure if this is the problem.

Anyway, version 3.6.2 has some fixes that improve on this. Is it 
possible for you to try the newer version ?
