I=20 have a means of doing an tune2fs -j on all of them remotely en mass but I'd rather not reboot them all to enable journaling on machines that are up and not having issues. I've tried to do a: mount -t ext3 -o remount /usr as well as just a mount -o remount after changing the fstab. on a test box but it just blows out a usage message. Is there a way to do this remount without a complete reboot that'll be transparant to users? If not, is it dangerous to tune2fs the filesystems, change the fstab and then leave the box up for 2-6 months and let them reboot through atrrition, upgrades, etc? Current kernel is 2.4.21-ac3, getting outages and upgrades is a rather long process involving regression testing, etc. Robert :wq! --------------------------------------------------------------------------- Robert L.
