Feature changed by: Gavin Rozzi (grozzi) Feature #311030, revision 10 Title: Add the new ZFS file system Kernel module openSUSE Distribution: Unconfirmed Priority Requester: Important Requested by: Di Pe (dipe) Partner organization: openSUSE.org Description: This is very cool, ZFS will be available on Linux in a few days and it will have decent performance. http://www.phoronix.com/scan.php?page=article&item=linux_kqzfs_benchmarks&num=1 http://zfs.kqinfotech.com/ Business case (Partner benefit): openSUSE.org: * ZFS is an Enterprise level file system that many poeple trust with large amounts of data (>100TB) * ZFS is much easier to use than the combination of linux RAID, LVM and EXT4 * ZFS supports checksumming which prevents bit rot. * ZFS supports compression and deduplication * strong support for ZFS will drive new users to openSUSE * Hardware RAID Controllers are adding a layer between OS and hard drives that can be hard to monitor with linux tools. * BTRFS is not yet ready today (it does not support RAID5 and is lacking many other features) * Ubuntu server will have it. Why would you not want ZFS? Discussion: #1: Jan Engelhardt (jengelh) (2011-01-10 02:54:26) Why one would not want ZFS? Because it has only seen serious use on Solaris, because that is where the money is. So excuse if I trust Linux implementations of ZFS only as much as the current btrfs. (And just because you did mention it: Ubuntu having something is not a meaningful metric. If anything, it's an indication of what not to do - think of 'startup') #2: Jimmy Berry (boombatower) (2011-01-10 03:46:37) (reply to #1) Amen to Ubuntu not being a metric. #3: Di Pe (dipe) (2011-01-22 15:14:59) (reply to #1) where the money is? Most storage people that like Linux see it this way: ZFS is the only reason Solaris is still of any use. If you are a Linux shop you want to avoid having to support Solaris as well. With opensolaris gone people are looking for alternatives for using ZFS. Have you seen the smashing success of nexenta.com which is opensolaris with debian userland tools? sure the current implementation of ZFS for Linux may not be rock solid yet, but neither is btrfs and that can be selected in yast (with a big warning). Why not doing the same for ZFS? #4: Di Pe (dipe) (2011-01-28 19:02:27) Currently, the Solaris porting layer does not build on openSUSE 11.3. They are going to try it out and make sure it will run on openSUSE. https://groups.google.com/group/kqstor-zfs-discuss/browse_thread/thread/b909... They also said that they have not had a single request to support SLE or openSUSE. If you want openSUSE support please drop a note google groups and things may go quicker. #5: Star Yang (net_walker) (2011-05-29 04:37:55) I am a home user and I am eager to look forwarding to ZFS in Linux. I have a lot data on my hands.(About 10TB so far) I need a safety and expandable and easy and lowcost solution for storage. I also ever downloaded solaris 10 from SUN web site. But it do not suit home-user. It can't be installed via my wireless keyboard and mouse. I had to buy a new wired keyboard-mouse suit to install it. And then I found it can't recognize my network card and can't auto config my network setting. + #6: Gavin Rozzi (grozzi) (2011-07-14 04:19:42) (reply to #5) + I agree, I as a home user tried Solaris 11 Express, and it's just not + for consumers. One of the things that did draw me there was the ZFS + filesystem. I found it to be great when using both large and normal + sized disks, and I too eagerly wait for Linux/openSUSE support of it. -- openSUSE Feature: https://features.opensuse.org/311030
