>>> I use an LVM logical volume as backing-store to my iSCSI target. I started tgtd, connected my initiator and then proceeded with resizing my logical volume by adding 5 GB. Next, I rescanned the disks from disk management (I'm using Windows as initiator), however, no size changed occured nor does tgtd say so.

Well I found it why it doesn't say %s changed and will never say that, inotify doesn't support block devices. Couldn't we implement a command in tgtadm that notifies tgtd it should re-read the sizes of its backing stores?
