[Gluster-users] Strange server locks isuess with 2.0.7 - updating

[Marek]

OK, we switched to 2.0.8. Till now we haven't any crash (yet), but some bricks still caught I/O dead lock (even with
disabled writebehind translator).
Some ppl on this group say that they have glusterfs running for a long period of time (months?) without aby problems,
maybe they should share with us how they did this :-)?


regards,
