lvm filtering /dev/dm-x and /dev/disk/by-id/dm-uuid-mpath-.*
I am wondering what is the different between both path in SLES11 SP2.
Since /dev/disk/by-id/dm-uuid-mpath-.* is the soft link of /dev/dm-x.
According to the document (7007498) << Using LVM on Multipath (DM MPIO) Devices>> , it is advised to use dm-name-*, or dm-uuid-mpath-*.
for example :
filter = [ "a|/dev/disk/by-id/dm-uuid-.*mpath-.*|", "r/.*/"]
filter = [ "a|/dev/disk/by-id/dm-name-.*|", "r/.*/"]
Could i just use the following filter?
filter = [ "a|/dev/dm.*|", "r/.*/"]
Thank you so much!
