Fixed In Version:
Doc Type: Bug Fix
Doc Text:
There is a new multipathd command, "resize map <mapname>". This command is used to cause dm-multipath to adjust to a change in the size of the underlying block storage device. Use the the following procedure, after you resize the underlying block device: # multipathd -k multipathd> del path <path-name> ok multipathd> add path <path-name> ok <repeat for each path to the device> multipathd> resize map <map name> For example: # multipath -ll mpath-resize-test (36090a018c032e4801e8e341700008039) dm-5 EQLOGIC,100E-00 [size=2.0G][features=0][hwhandler=0][rw] \_ round-robin 0 [prio=1][active] \_ 2:0:0:0 sdd 8:48 [active][ready] \_ round-robin 0 [prio=1][enabled] \_ 3:0:0:0 sdc 8:32 [active][ready] # multipathd -k multipathd> del path sdc ok multipathd> add path sdc ok multipathd> del path sdd ok multipathd> add path sdd ok multipathd> resize map mpath-resize-test ok There is one restriction on the use of the device mapper multipath resize command. You can not resize a device-mapper device while there commands queued to that device. That is, do not use the resize command when no_path_retry is set to "queue", and there are no active paths to the device.

Cloned from 5.3 - similar to the kernel space, this is for the user space. Please edit the release notes if appropriate, they were copied over from 5.3 as well.

This bug depends on the kernel bug 454872.
