BTW, that probably damamged your filesystem, and you should probably force a fsck. UFS assumes exclusive access, and if another system is modifying the same structures, they will write all over each other. When you umount and mount on the one system, it doesn't see the changes, because it assumes nothing has changed since the last time it had the disk mounted. > This being a nice setup I would like to be able to access (add/delete) at the > same time from both servers.

I'm not aware of too many filesystems that can do this. > Alternitavily, how can a remount the parition without having to reboot to be > able to see all the new data.

Basically, treat it as pseudo removable disk. > e. > _______________________________________________ > freebsd-isp@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-isp > To unsubscribe, send any mail to "freebsd-isp-unsubscribe@freebsd.org" > >
