If using LVM it's possible to do this entirely at the LVM layer without interrupting the filesystem, I wouldn't recommend it without first taking a backup though. The commands used for this are pvcreate, vgextend, pvmove, vgreduce and pvremove. If using tar make sure you do a test run first, we've found several bugs with tar recently that lead to errors. https://bugzilla.redhat.com/show_bug.cgi?id=656834 Ashley. _______________________________________________ Lustre-discuss mailing list [email protected] http://lists.lustre.org/mailman/listinfo/lustre-discuss
