xfsdump historically has truncated the inode generation number to the low
12 bits when writing out directory entries. This makes it possible for
xfsrestore to mistakingly think 2 directory entries refer to the same
inode when dealing with incremental or resumed dumps. A message such as
this is an indication of this problem:
xfsrestore: WARNING: unable to unlink current file prior to restore
This patch changes xfsdump to use the full 32-bit inode generation number.
A change to part of the dump format (direnthdr_t) was required, so the
dump format version has been bumped to 3. xfsdump also required changes to
its inode-to-generation cache. This map is not persistent though, so no
compatibility or version changes were required there.
xfsrestore has been changed to support the old and new dump formats. This
required a change to its persistent data structures (for cumulative
restores), so that version number was bumped as well.
When restoring a series of incremental/resumed dumps, if the oldest
restore used 12-bit generation numbers then they will be used throughout
the restore series to avoid mass confusion. It's recommended that users do
a level 0 backup of their filesystems with the new xfsdump so that future
incremental restores can take advantage of the full 32-bit generation
number.
