ZFS completely fragments if you've got massive parallel write IO - especially with Solaris 11. You'll get only 2..3 MiB/s after some time as everything is stored completely random then. So if you don't really need these snapshots you shouldn't use ZFS. NILFS is also good for snapshots. > On 2/14/13 9:39 AM, Roy Sigurd Karlsbakk wrote: >> I don't feel like using the fuse version, but is zfsonlinux really >> stable yet? >> >> ----- Opprinnelig melding ----- >>> Roy, >>> >>> Why not use ZFS on Linux?
