Hi ! Everyone!

=C2=A0 =C2=A0Is anyone tried to add an ssd cache to node using= bcache or flashcache?

=C2=A0 =C2=A0It seemed that we have to change the procedure wh= en adding a storage domain .

=C2=A0 =C2=A0Maybe it can be done in serveral days , but sync = the cache between nodes seemed a little tricky.

=C2=A0 =C2=A0Do you have any idea?

I use dm-cache on rhel7 on one of my storages. It works. It has nothing to do with ovirt however, everything is managed by the storage server.
