Not sure if you copy individual files or all partition (dd(1) or so), but would be enough to use fsfreeze(8) to avoid umount/mount? I guess you can call fsck on duplicated partition on the second disk. IMHO fsfreeze is less invasive than umount. Or use LVM snapshots ;-) Karel -- Karel Zak <k...@redhat.com> http://karelzak.blogspot.com _______________________________________________ systemd-devel mailing list email@example.com https://lists.freedesktop.org/mailman/listinfo/systemd-devel
