Re: Running instances on ceph with openstack

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello Ali Shah,

we are running VMs using Opennebula with ceph as the backend. So far
with varying results: From time to time VMs are freezing, probably
panic'ing when the load is too high on the ceph storage due to rebalance
work.

We are experimenting with --osd-max-backfills 1, but it hasn't solved
the problem completly.

Cheers,

Nico
