Hello,
Question:
Can a utility program be written to swap 2 nodes over given the Node
number and 2 'Wrong order of keys' ?
[reiser4progs] fsck.reiser4 commands fail to repair file system [1] is the
reason I ask for this.
[1]
--build-sb
--build-fs
--fix
e.g
# fsck.reiser4 --build-sb --build-sb /dev/sdb
# fsck.reiser4 --build-fs --build-fs /dev/sdb
# fsck.reiser4 --fix /dev/sdb
# fsck.reiser4 --fix --help
Usage: fsck.reiser4 [ options ] FILE
Fsck options:
--check checks the consistency (default)
--fix fixes minor corruptions
--build-sb rebuilds the super block
--build-fs rebuilds the filesystem
.
