[ovirt-users] Sanlock invalid lockspace found

[Marco Büttner]

Hi there,

we have a big problem with our ovirt 4.1.1 enviroment.
After a fc-storage failure, and an automatic reboot of the host with the 
hosted engine on it, we can't get the engine running again.

The probelm seems an invalid lockspace. Sanlock.log shows:

Manualy it is possible to mount the HE Image on the host. A 
filesystemcheck  reports that all is clean. Also it is possible to 
create a file in the mounted engine image.
If I remove the lockspace manuelly, it comes back within about 10 seconds.

Enviroment ovirt 4.1.1 latest onn image + HE Appliance

Also tested hosted-engine --reinitialize-lockspace completes without errors.

Anybody any ideas? Would be very very great....
