When multipath is enabled and friendly names are ON and we try to extend a volume, we pass the SCSI WWID to the multipath_resize_map method which is not correct. There are 2 things we can pass to the multipathd resize map command: 1) Multipath device (eg: dm-0) 2) Alias (eg: mpath1) or UUID (eg: 36005076303ffc56200000000000010aa) The value should be an alias (mpath1) when friendly names are ON and UUID (36005076303ffc56200000000000010aa) when friendly names are OFF. However, we only pass the UUID irrespective of the value set for friendly names. This patch passes the multipath device path (to multipathd resize map command) which is the real path of the multipath device (/dev/dm-*). This fixes the issue as it passes the same value irrespective of if the friendly names are ON or OFF. -> self.multipath_resize_map(os.path.realpath(mpath_device)) (Pdb) mpath_device '/dev/disk/by-id/dm-uuid-mpath-3600140522774ce73be84f9cb9537e0c9' (Pdb) os.path.realpath(mpath_device) '/dev/dm-5' Closes-Bug: 1609753 Change-Id: I1c60af19c2ebaa9de878cd07cfc0077c5ea56fe3
