Hi everyone :-) Just one question for the gurus here. I was wondering: if I disable write barriers in btrfs with the mount option nobarrier I just disable the periodic flushes of the hardware disk cache or I'm disabling also the order of the writes directed to the hard disk? What I mean is: is it safe to disable write barrier with a UPS with which I will likely have the hardware always powered even in the event of a kernel crash, freeze, etc? I'm asking because if also the ordering of the write is no more guaranteed I guess it would not be safe to disable write barrier even if the possibility of an unexpected power down of the HD was remote because in the case of a crash the order of the write would be messed up anyway and we could boot up with a completely corrupted fs. Thank you very much for your kinds answers.
