Subject: [PATCH] xfsrestore: fix rootdir due to xfsdump bulkstat misuse
|
||||||
|
|
||||||
|
If rootino is wrong and misspecified to a subdir inode #,
|
||||||
|
the following assertion could be triggered:
|
||||||
|
assert(ino != persp->p_rootino || hardh == persp->p_rooth);
|
||||||
|
|
||||||
|
This patch adds a '-x' option (another awkward thing is that
|
||||||
|
the codebase doesn't support long options) to address
|
||||||
|
problamatic images by searching for the real dir, the reason
|
||||||
|
that I don't enable it by default is that I'm not very confident
|
||||||
|
with the xfsrestore codebase and xfsdump bulkstat issue will
|
||||||
|
also be fixed immediately as well, so this function might be
|
||||||
|
optional and only useful for pre-exist corrupted dumps.
|
||||||
|
|
||||||
|
In details, my understanding of the original logic is
|
||||||
|
1) xfsrestore will create a rootdir node_t (p_rooth);
|
||||||
|
2) it will build the tree hierarchy from inomap and adopt
|
||||||
|
the parent if needed (so inodes whose parent ino hasn't
|
||||||
|
detected will be in the orphan dir, p_orphh);
|
||||||
|
3) during this period, if ino == rootino and
|
||||||
|
hardh != persp->p_rooth (IOWs, another node_t with
|
||||||
|
the same ino # is created), that'd be definitely wrong.
|
||||||
|
|
||||||
|
So the proposal fix is that
|
||||||
|
- considering the xfsdump root ino # is a subdir inode, it'll
|
||||||
|
trigger ino == rootino && hardh != persp->p_rooth condition;
|
||||||
|
- so we log this node_t as persp->p_rooth rather than the
|
||||||
|
initial rootdir node_t created in 1);
|
||||||
|
- we also know that this node is actually a subdir, and after
|
||||||
|
the whole inomap is scanned (IOWs, the tree is built),
|
||||||
|
the real root dir will have the orphan dir parent p_orphh;
|
||||||
|
- therefore, we walk up by the parent until some node_t has
|
||||||
|
the p_orphh, so that's it.

|
|

|
The invalid start and end inode information cause xfsrestore to consider
|
||||||
|
that non-directory files do not reside in the current media and will
|
||||||
|
fail to restore them.
|
||||||
|
|
||||||
|
The behaviour of an initial restore may succeed if the position of the
|
||||||
|
tape is such that the data file is encountered before the inventory
|
||||||
|
file, or if there is only one dump session on tape, xfsrestore is
|
||||||
|
somewhat inconsistent in this regard. Subsequent restores will use the
|
||||||
|
invalid on-line inventory and fail to restore files.
|
||||||
|
|
||||||
|
Fix this by correctly unpacking the inventory data.

Subject: [PATCH 2/4] xfsrestore: fix on-media inventory stream unpacking
|
||||||
|
|
||||||
|
xfsdump can create multiple streams, when restoring the online inventory
|
||||||
|
with multiple streams we fail to process these and assert when the
|
||||||
|
inventory buffer is not fully decoded.
|
||||||

Subject: [PATCH 3/4] xfsdump: fix on-media inventory stream packing
|
||||||
|
|
||||||
|
With the on-media inventory now being restored for multiple streams we
|
||||||
|
can see that the restored streams both claim to be for /dev/nst0.
|
||||||
|
|
||||||
|

||||||
