Dear all,
Currently I testing KVMs running on ceph and particularly testing recent
cache feature. Performance is of course vastly improved but still have
occasional KVM hold ups - not sure who is at blame ceph of KVM. But I
will deal with it later. Right now I've got myself a question which I
could not get answered myself: if I do live migration of KVM while there
some uncommitted data in ceph cache will this cache be committed prior
cut-over to another host? Reading through the list I've got an
impression that it may be left uncommitted and thus it may cause data
corruption. I just would like a simple confirmation if code which
commits cache on cut-over to new host does exist and no data corruption
due to RBD cache+live migration should happen.
Regards,
Vladimir
