Hi list,
- has anyone tried SUN's ZFS on SuSE? Can it be done, is it at all feasible?
- or another Distributed file system. I may need a file system, that will allow me to add storage ad hoc.
Any hints, links?
I haven't tried, but the only way to use zfs on linux would be through FUSE, in userland, due to license incompatibility. Aditionaly, zfs is not a distributed file system (but indeed would let you add storage later, as it has some sort of pool, like in an lvm volume). ZFS through FUSE would have worse performance, I guess. It was asked the advantages of ZFS, and there are lots (check the wikipedia articles), mainly end-to-end data integrity (imho) and other functionalities (copy on write, snapshots, no need to format, no need to fsck, simplified syntax for userland tools, etc). It's only possible because its layout somewhat breaks the usualy fs layout in linux, incorporating for example, the raid layer in the filesystem. This video shows a lot of what it can do: http://opensolaris.org/os/community/zfs/demos/basics/ The closest thing in linux land would be oracle's btrfs, but its beta or alpha, dunno. Aditionaly ext4 may give you some functionalities that zfs has (snapshots, copy-on-write). For distributed file systems you would have to take a look at lustrefs (also from Sun), IBM's GPFS, Red Hat's GFS, openAFS, it varies a lot hardware/software/application-wise Storage specific filesystems, like SAM-QFS (SUN), ocfs2 (oracle) are yet another thing, and they are more suitable when there is a SAN. Check http://en.wikipedia.org/wiki/List_of_file_systems#Distributed_file_systems and http://en.wikipedia.org/wiki/Shared_disk_file_system and others for a good start Cheers Marcio --- Druid -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
