I re-tested this new patch series using an iSCSI target via the following steps: 1) Connect to iSCSI storage, creating the /dev/sd* devices. 2) Create a file system on the block device 3) Mount the file system, and leave a shell active on the mount point. 4) resize the iSCSI LUN 5) rescan the iSCSI session 6) resize the file system This procedure worked fine.
