For the last week or two on Fedora 21, none of my storage pools have been started on boot, despite being configured to. I believe this is related to them all being on a CIFS share (/share/data ). On boot I have these messages in journal: Jul 28 07:46:33 adam.happyassassin.net libvirtd[1497]: libvirt version: 1.2.6, package: 2.fc21 (Fedora Project, 2014-07-23-09:01:58, buildvm-03.phx2.fedoraproject.org) Jul 28 07:46:33 adam.happyassassin.net libvirtd[1497]: cannot open path '/share/data/isos/RH7': No such device Jul 28 07:46:33 adam.happyassassin.net libvirtd[1497]: Failed to autostart storage pool 'RH7': cannot open path '/share/data/isos/RH7': No such device Jul 28 07:46:33 adam.happyassassin.net libvirtd[1497]: cannot open path '/share/data/isos/20': No such device Jul 28 07:46:33 adam.happyassassin.net libvirtd[1497]: Failed to autostart storage pool '20': cannot open path '/share/data/isos/20': No such device Jul 28 07:46:33 adam.happyassassin.net libvirtd[1497]: cannot open path '/share/data/isos/19': No such device Jul 28 07:46:33 adam.happyassassin.net libvirtd[1497]: Failed to autostart storage pool '19': cannot open path '/share/data/isos/19': No such device Jul 28 07:46:33 adam.happyassassin.net libvirtd[1497]: cannot open path '/share/data/isos': No such device Jul 28 07:46:33 adam.happyassassin.net libvirtd[1497]: Failed to autostart storage pool 'isos': cannot open path '/share/data/isos': No such device Jul 28 07:46:33 adam.happyassassin.net libvirtd[1497]: cannot open path '/share/data/isos/vms': No such device Jul 28 07:46:33 adam.happyassassin.net libvirtd[1497]: Failed to autostart storage pool 'NAS': cannot open path '/share/data/isos/vms': No such device This may have started when I set up bridging, actually (as it means my network takes longer to come up at boot). I believe having After=network-online.target , not After=network.target , in libvirtd.service would help with this, but I'm not sure if it may be undesirable in other configurations. If so, perhaps libvirtd could try again to bring up storage pools on network shares later, if they fail at first try?
Adding a network-online dep would likely fix most instances of bug 867546 as well, but there could be downsides. Someone would need to test
This message is a reminder that Fedora 21 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 21. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '21'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 21 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
There's an "After=remote-fs.target" in libvirtd now, and I don't *think* I've seen this bug lately. Let's call it good.
