[Bug 1486370] Re: ISST-LTE: not all mpath device files are symbol link

[Mauricio Faria de Oliveira]

This is working correctly w/ kpartx.
One instance it seems to be still generating symlinks/nodes intermixed is when using parted.
However, during reboot and post-boot kpartx invocation, it is pretty consistent w/ only nodes.
So, this seems correct with regards to the code in multipath-tools.
Marking verification-done.

After parted:

# ls -l /dev/mapper/mpath1*
brw-rw---- 1 root disk 252, 1 Feb  9 11:26 /dev/mapper/mpath1
brw-rw---- 1 root disk 252, 3 Feb  9 11:16 /dev/mapper/mpath1-part1
lrwxrwxrwx 1 root root      7 Feb  9 11:16 /dev/mapper/mpath1-part2 -> ../dm-6
lrwxrwxrwx 1 root root      7 Feb  9 11:17 /dev/mapper/mpath1-part3 -> ../dm-7
lrwxrwxrwx 1 root root      7 Feb  9 11:17 /dev/mapper/mpath1-part4 -> ../dm-8
lrwxrwxrwx 1 root root      7 Feb  9 11:26 /dev/mapper/mpath1-part5 -> ../dm-9
lrwxrwxrwx 1 root root      8 Feb  9 11:26 /dev/mapper/mpath1-part6 -> ../dm-10
lrwxrwxrwx 1 root root      8 Feb  9 11:26 /dev/mapper/mpath1-part7 -> ../dm-11
lrwxrwxrwx 1 root root      8 Feb  9 11:26 /dev/mapper/mpath1-part8 -> ../dm-12

After reboot:

# ls -l /dev/mapper/mpath1*
brw-rw---- 1 root disk 252,  1 Feb  9 11:28 /dev/mapper/mpath1
brw-rw---- 1 root disk 252,  3 Feb  9 11:28 /dev/mapper/mpath1-part1

brw-rw---- 1 root disk 252, 12 Feb  9 11:28 /dev/mapper/mpath1-part8

After a series of kpartx -d/-a -p -part:

# ls -l /dev/mapper/mpath1*
brw-rw---- 1 root disk 252,  1 Feb  9 11:34 /dev/mapper/mpath1
