Description David Jaša 2013-10-31 18:37:52 UTC
Description of problem:
some SANs allow online LUN extension. Using that in RHEV currently means some manual work:
1) on all hosts, rescan iscsi disks: echo "1" > /sys/block/sdX/device/rescan
2) on all hosts, resize multipathed device: multipathd -k'resize map dm-Y'
3) on SPM, run: pvresize /dev/dm-Y
4) let engine know current storage size (can be done by force-switching engine)

Version-Release number of selected component (if applicable):
encountered on 3.2

How reproducible:

Steps to Reproduce:
1. extend online backing iscsi LUN
2. try to make use of the new space in RHEV-M

Actual results:

Expected results:
