[Gluster-users] Strange side-effect to "option base-port 50152"

[Paul Boven]

Hi folks,

While debugging the migration issue, I noticed that sometimes we did in 
fact occasionally hit but 987555 ("Address already in use") when doing a 
live-migration, so I decided to implement the advice in aforementioned bug.

So I set 'option base-port 50152' in /etc/glusterfs/glusterd.vol (note 
that the bug talks about /etc/glusterfs/gluster.vol, which doesn't 
exist). The result of this was that migrations completely stopped 
working. Trying to do a migration would cause the process on the sending 
machine to hang, and on the receiving machine, libvirt became completely 
unresponsive, even 'virsh list' would simply hang.

Curiously, 'gluster volume status' showed that, despite setting the 
base-port to 50152, the bricks were still listening on 49152, as before 
the config change & reboot.

I reverted my change to 'option-base-port', did another set of reboots, 
and now migration is 'working' again, as in the guest gets moved across, 
but then still loses access to its image (see my other mails).

Ubuntu 13.04, glusterfs-3.4.1.

Regards, Paul Boven.
