James Slagle 8d910d10f8 Wait for tgtd socket to be available ... tgtd returns execution control and backgrounds itself almost immediately and before it has made it's listening socket available. This can cause a race condition as the tgtd socket is not available when tgtadm is run, resulting in an error: failed to send request hdr to tgt daemon Add a function to check if the socket is available before moving on to calling tgtadm, and a wait_for helper function we can use. We'll check for the socket every 0.5 seconds, for up to 5 seconds. I'm seeing this issue on almost every deploy using a ramdisk built from Fedora 20. I'm not sure if something has changed in tgtd, but this behavior is documented since Fedora 18 at least. In the systemd script for tgtd, there is actually "sleep 5" to work around the problem.
