Dupd.c8 * Jan 2007: Alexander Schmidt, hacked per-volume update.
12 * This file contains implementation of the volume update and atomic LEB change
15 * The update operation is based on the per-volume update marker which is
16 * stored in the volume table. The update marker is set before the update
17 * starts, and removed after the update has been finished. So if the update was
18 * interrupted by an unclean re-boot or due to some other reasons, the update
20 * device next time. If the update marker is set for a volume, the volume is
21 * treated as damaged and most I/O operations are prohibited. Only a new update
24 * Note, in general it is possible to implement the update operation as a
34 * set_update_marker - set update marker.
