[ovirt-users] oVirt 3.5.1 - VM "hostedengine" Failing to start

Wed Jan 28 04:04:39 EST 2015

Note,  since removing the file the hosted_engine1 is starting up and everything seems fine but then all of a sudden it restarts.

I assume this is an nfs issue so I checked to see if I could create a file in the mounts from the host machine,  which I could.

My test bed is usign an old OS X NFS via xraid adn the export is ;
/Volumes/Raid1 -maproot=root:wheel -network 192.168.1.0 -mask 255.255.255.0

drwxr-xr-x    6 vdsm   kvm      204 Jan 27 16:30 443b4931-667f-441f-98d8-51384e67a0af
drwxr-xr-x    4 vdsm   kvm      136 Jan 27 12:32 data
drwxr-xr-x    4 vdsm   kvm      136 Jan 27 00:18 iso
drwxr-xr-x    3 vdsm   kvm      102 Jan 26 09:43 vm

the host machine seems to mount the shares fine....

drwxr-xr-x  5 vdsm kvm 4096 Jan 27 12:28 .
drwxr-xr-x  3 vdsm kvm 4096 Jan 27 10:04 ..
drwxr-xr-x 13 vdsm kvm  544 Jan 27 00:12 192.168.1.32:_Volumes_Raid1
drwxr-xr-x  2 vdsm kvm 4096 Jan 27 00:12 192.168.1.32:_Volumes_Raid1_data
drwxr-xr-x  2 vdsm kvm 4096 Jan 27 00:24 192.168.1.32:_Volumes_Raid1_iso

and as I said above I can create files in any one of those mounts

Is there a place I can look at to find the offending file?  If that is the issue...  Oddly enough everything worked until i rebooted, so I must have either changed something or something is buggered.

please echo the output of

find  /Volumes/Raid1 -name "__DIRECT_IO_TEST__" | xargs ls -la

the failure is to create this file.
