[ovirt-users] hosted engine - can't contact destroyed storage

[James Clarke]

Might as well admit to fixing it myself.  SSH'd to the host and saw that this share was mounted.  Forced an umount and now the host is up.


Weird, but working.


Thanks,

James

?Hi All!


I decommissioned a NFS export domain this morning, ended up 'destroying' it through the web interface as detaching kept failing.?  Now one of my hosts keeps flipping between 'Non Operational' and 'Unassigned'.  All of the VMs on this host are still running.  I am in global-maintenance to prevent migrations etc.


vdsm.log seems to indicate that it is related to connecting to the destroyed storage domain:


Thread-206::WARNING::2014-09-02 12:19:05,692::fileSD::673::scanDomains::(collectMetaFiles) Metadata collection for domain path /rhev/data-center/mnt/10.0.0.30:_mnt_kvm1_export timedout

Timeout


Given that this storage domain doesn't exist any more and is not visible in the web interface, how can I get this host to stop trying to connect to it, initialize and become online?
