ZFS-FUSE 0.5.0 was released a few days ago and brought some nice changes. I’ve been using ZFS-FUSE on a number of systems for the purpose of snapshotting the virtual disks of virtual servers. ZFS-FUSE seems to perform well under this scenario. I’d say the major changes are asynchronous IO support, disk barrier support (flushing the write cache), support for zfs send and recv, and a healthy number of bug fixes. I had been using the 0.4.x version straight from the mercurial repository but now I’m switching to this new release. Here are the install steps I followed.
