Doc Type:	Bug Fix
Doc Text:	Cause: If multipath failed to resize a multipath device, the device would be left in the SUSPENDED state. Consequence: multipath devices would become unusable if a resize on them fails. Fix: If a resize fails, multipath will now resume using the device with the previous size. Result: When resizing a multipath device fails, the device is still usable.

Comment 1 Ben Marzinski 2017-09-19 20:08:10 EDT

When multipath can't resize a map because both of the paths are not the same size, it will end up stuck in the suspended state.  The best solution here is to simply try to resume the device with the original size again.
