Doc Type:	Bug Fix
Doc Text:	Multiple calls to resize a device will each attempt to resize the device, and will correctly report the result Previously, if `multipathd` failed to resize a device, it continued to think that the device had the new size. Subsequent calls to resize the device would report success and not resize the device because `multipathd` thought that it had nothing left to do. With this fix, `multipathd` now resets the device size to the original size if the resize fails. As a result, multiple calls to resize a device will each attempt to resize the device, and will correctly report the result.

Comment 2 Ben Marzinski 2016-06-03 14:44:46 EDT

When multipath failed the resize, it was still thinking it had the larger size internally.  Thus, when the second resize command happened, it through that it had nothing to do, and returned success. I've made it reset it's size internally, when the resize command fails.
