[ovirt-users] oVirt Hosted Engine Backup and Restore guide

2017-10-03 Thread Alexander Vrublevskiy

Hello Community!

I'm looking for information about Hosted Engine backup and restore procedures. 
There's HE how-to which refers to oVirt Hosted Engine Backup and Restore guide:
https://www.ovirt.org/documentation/how-to/hosted-engine/#hosted-engine-backup-and-restore
  

but the link leads to 404 error.

Could anyone provide working link to the document, please?

And the main point why I'm looking for it is HE migration: we need to move HE 
to another data center. It'd be awesome if someone could share experience of 
such migration or at least point the direction to explore.

Thanks in advance!
Regards
Alex

[ovirt-users] SPM recovery after disaster

2017-10-02 Thread Alexander Vrublevskiy

Hello Community!
Recently we had a disaster with our oVirt 4.1 three nodes cluster 
with HE and GlusterFS (RF=3) storage domain. We've moved one node to 
maintenance and during actual maintenance one of working nodes with SPM 
role went down. It was hardware failure so we had to remove it from the 
cluster.
After tinkering around now we have almost working cluster with two 
nodes and with GlusterFS RF=2. But the problem is oVirt can't find SPM 
and spaming web interface logs with "HSMGetAllTasksStatusesVDS failed: 
Not SPM" error.
After some time of operating with stated configuration we lost contents of 
dom_md somehow.
Looks like these two problems are related and second one is a consequence of 
the first.
Please suggest how to recover SPM and dom_md. Is there a way to recreate both?
TIA
