Hi all,
In libvirt/src/storage/storage_backend_sheepdog.c file, func
virStorageBackendSheepdogCreateVol calls func
virStorageBackendSheepdogRefreshVol to refresh Sheepdog volume infos.
But we do not check func virStorageBackendSheepdogRefreshVol's return
value. Following patch can fix this bug.

Thanks for attempting a patch. However, the commit message is
unconventionally formatted; did you use 'git send-email' to send your
patch, as suggested in HACKING? We would have to amend the message to
get rid of the 'Hi all,' line, as well as the unusual 'Subject:' line
after a sign-off.

This patch fails 'make syntax-check', because it used TABs. Also, we
tend to use (ret < 0), not (0 > ret), even though they are equivalent.

Would you mind resubmitting to touch up those issues?
