I want to setup multiple similar containers and I want to have de-duplication. The only solution I'm thinking of is to use OpenSolaris ZFS and share zfs volume with NFSv4 ro iSCSI target and create usual ext3 fs on it to use as OpenVZ VE storage.
Any other solutions for de-duplication?
What are your thoughts on that? Pos/Cons?
P.S. I've tried ZFS-fuse and it's consuming a lot of CPU even without significant containers usage. Bad idea anyway and for sure is bad for production Native Linux ZFS port is very unstable now
