[HPDD-discuss] enabling file locking - lustre 1.8.8

Hello, Recently the question was asked if we could enable file locking on our lustre file system (because of automake/autoconf). We are currently running lustre 1.8.8 on our mds/loss servers, which apparently doesn't support (or it isn't enabled) file locking. Is this something that could be done, non-destructively, to the current system... or would we have to upgrade to a newer version? w/r, Kurt J.
