-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all I've rebooted a host after a kernel update (from 3.8.2 to 3.8.9), after which it refuses to go online again. Instead, it ends up as "non-operational" since the host cannot connect one of the Storage Domains. The Datacenter is of iSCSI Type, with compat version of 3.2. It currently contains 4 hosts plus the one running only the engine, each having a single software raid array which is an iSCSI target. Thus there is one storage domain for each host. All hosts run Fedora 18, the 3 other hosts are running just fine. I've tried rebooting, reinstalling, setting the host to maintenance and activate again, etc, without any change in status. Doing a 'systemctl restart vdsmd' gives no output whatsoever. Some logs/outputs I have found: Note: The interesting time is mostly May 01 from 14:30 to 15:00, but there were a number of attempts earlier that day. systemctl status vdsdm on the problematic host: May 01 14:51:59 galaxy4 vdsm[2706]: vdsm Storage.HSM WARNING disconnect sp: 4b8e315f-6d4a-432e-b5b2-cba26f5987d8 failed.
