Hi all,
Some users (#471729) manage to end up with /dev/dm-X instead of
/dev/Foo/Bar in their /etc/fstab (don't ask how I dunno). Given that
this is not the first time AFAIK. I've written a patch to handle this
properly (as long as the /dev/dm numbering does not change).
This patch does 3 things:
1) Properly handle slave links, so that our sysfs slave walking code
actually walks the slaves properly
2) Check if a devicemapper device is an lv inside handledm
3) remove handlevordev, as this check is now done in handledm
I've tested this with various setups using mount by LABEL UUID
/dev/mapper/XXX /dev/Foo/Bar and /dev/dm-x and all work properly.
