I googled this error. It seems a Fedora error. It is report that disabling sandbox service and restarting the computer can fix the problem. However the cause is not clear, the bug remains 'new' on the bugzilla. The link is https://bugzilla.redhat.com/show_bug.cgi?id=808795#c31

Failed where? On your own host? Is it reproducible? We had a similar, but transient, problem in http://jenkins.ovirt.org/job/vdsm_unit_tests/143/console
We, or some other suite using the server, may be leaking a loop device. Eyal Edri, do you know what has made this go away in run #144?
the test execute 'mount' and 'umount' command. after the umount command, the loop device can not be freed
here is the log: -------------------->> begin captured logging<< -------------------- Storage.Misc.excCmd: DEBUG: 'dd if=/dev/zero of=/tmp/tmpH2KSCr bs=100M count=1' (cwd None) Storage.Misc.excCmd: DEBUG: SUCCESS:<err> = '1+0 records in\n1+0 records out\n104857600 bytes (105 MB) copied, 0.266024 s, 39 4 MB/s\n';<rc> = 0 Storage.Misc.excCmd: DEBUG: 'losetup -f --show /tmp/tmpH2KSCr' (cwd None) Storage.Misc.excCmd: DEBUG: FAILED:<err> = 'losetup: could not find any free loop device\n';<rc> = 255 --------------------->> end captured logging<< ---------------------
Does your Linux host have a trace of the generated loop device? What says losetup -a ? _______________________________________________ vdsm-devel mailing list vdsm-devel@lists.fedorahosted.org https://fedorahosted.org/mailman/listinfo/vdsm-devel
