On systems where is multi-path storage device is problem with duplicated
filesystems. The solution is select "the best" device. This is possible
by device-mapper library.
Short quotation from RH bugzilla:
With my patch, all dm devices remains in libblkid cache.
Only the top level dm devices are given high priority
and more appropriate node names (i.e. /dev/mapper/*) are used.
For example, if we have linear mapped dm device "ov1" over
dm device "disk1p3" which is multipath mapped to /dev/sdd3 and /dev/sdh3:
# dmsetup.static ls --tree
ov1 (253:5) <-- /dev/mapper/ov1 or /dev/dm-5
`-disk1p3 (253:4) <-- /dev/mapper/disk1p3 or /dev/dm-4
`-disk1 (253:0)
|- (8:112) <-- /dev/sdh
`- (8:48) <-- /dev/sdd
Original version of blkid will show:
# ./orig/blkid -t LABEL=mpdisk1p3 -l
/dev/sdd3: LABEL="mpdisk1p3" ... TYPE="ext3"
With my patch, blkid will show:
# ./deptree/blkid -t LABEL=mpdisk1p3 -l
/dev/mapper/ov1: LABEL="mpdisk1p3" ... TYPE="ext3"
In blkid cache, all devices are listed:
# ./orig/blkid -t LABEL=mpdisk1p3
/dev/sdd3: LABEL="mpdisk1p3" ... TYPE="ext3"
/dev/sdh3: LABEL="mpdisk1p3" ... TYPE="ext3"
/dev/dm-4: LABEL="mpdisk1p3" ... TYPE="ext3"
/dev/dm-5: LABEL="mpdisk1p3" ... TYPE="ext3"
# ./deptree/blkid -t LABEL=mpdisk1p3
/dev/mapper/ov1: LABEL="mpdisk1p3" ... TYPE="ext3"
/dev/sdd3: LABEL="mpdisk1p3" ... TYPE="ext3"
/dev/sdh3: LABEL="mpdisk1p3" ... TYPE="ext3"
/dev/dm-4: LABEL="mpdisk1p3" ... TYPE="ext3"

README
This is the new version (1.38) of the second extended file system management programs. From time to time, I release new versions of e2fsprogs, to fix bugs and to make the utilities more robust. You can always find information about the latest version at the the e2fsprogs web page, which is: http://e2fsprogs.sourceforge.net The INSTALL file has instructions on building and installing e2fsprogs. Provisions for building Red Hat RPMs and Debian dpkg files are supplied as well. In case of bugs in these programs, please contact Ted Ts'o at tytso@thunk.org or tytso@alum.mit.edu. See the e2fsck man page for suggestions of what sort of information to include when submitting bug reports for these programs.
