Re: [zfs-discuss] future of OpenSolaris
I think Oracle have been quite clear about their plans for OpenSolaris. They have publicly said they plan to continue to support it and the community. They're just a little distracted right now because they are in the process of on-boarding many thousand Sun employees, and trying to get them feeling happy, comfortable and at home in their new surroundings so that they can start making money again. The silence means that you're in a queue and they forgot to turn the hold music on. Have patience. :-) On 02/22/10 09:22, Eugen Leitl wrote: Oracle's silence is starting to become a bit ominous. What are the future options for zfs, should OpenSolaris be left dead in the water by Suracle? I have no insight into who core zfs developers are (have any been fired by Sun even prior to the merger?), and who's paying them. Assuming a worst case scenario, what would be the best candidate for a fork? Nexenta? Debian already included FreeBSD as a kernel flavor into its fold, it seems Nexenta could be also a good candidate. Maybe anyone in the know could provide a short blurb on what the state is, and what the options are. smime.p7s Description: S/MIME Cryptographic Signature ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] Size discrepancy (beyond expected amount?)
You also DON'T want to give a single disk to your rpool. ZFS really needs to be able to fix errors when it finds them. Suggest you read the ZFS Best Practices Guide (again). http://www.solarisinternals.com/wiki/index.php/ZFS_Best_Practices_Guide#Storage_Pools Mike Tomas Ögren wrote: On 19 March, 2009 - Harry Putnam sent me these 1,4K bytes: I'm finally getting close to the setup I wanted, after quite a bit of experimentation and bugging these lists endlessly. So first, thanks for your tolerance and patience. My setup consists of 4 disks. One holds the OS (rpool) and 3 more all the same model and brand, all 500gb. I've created a zpool in raidz1 configuration with: zpool create zbk raidz1 c3d0 c4d0 c4d1 No errors showed up and zpool status shows no problems with those three: pool: zbk state: ONLINE scrub: none requested config: NAMESTATE READ WRITE CKSUM zbk ONLINE 0 0 0 raidz1ONLINE 0 0 0 c3d0ONLINE 0 0 0 c4d0ONLINE 0 0 0 c4d1ONLINE 0 0 0 However, I appear to have lost an awfull lot of space... even above what I expercted. df -h [...] zbk 913G 26K 913G 1% /zbk It appears something like 1 entire disk is gobbled up by raidz1. The same disks configured in zpool with no raidz1 shows 1.4tb with df. I was under the impression raidz1 would take something like 20%.. but this is more like 33.33%. So, is this to be expected or is something wrong here? Not a percentage at all.. raidz1 takes 1 disk. raidz2 takes 2 disks. This is to be able to handle 1 vs 2 any-disk failures. Then there's the 1000 vs 1024 factor as well. Your HD manufacturer says 500GB, the rest of the computer industry says ~465.. /Tomas smime.p7s Description: S/MIME Cryptographic Signature ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Re: [zfs-discuss] Disk usage
Well, it is kinda confusing... In short, df -h will always return the size of the WHOLE pool for size (unless you've set a quota on the dataset in which case it says that), the amount of space that particular dataset is using for used, and the total amount of free space on the WHOLE pool for avail (unless you've got a quota or reservation set). So in your original mail. 695G is the size of the DATA on the r12_data pool. zfs list r12_data says you are using 596G. I think this is the RAW capacity used, and I reckon you are using compression. (zfs get compressratio r12_data will give you something like 1.1). However, df -h of r12_data/d24 should have the identical 1st and 3rd fields, but they don't. (Could you re-run?) Same goes for the zfs list commands. Could you try doing zfs list -o space to get a fuller breakdown of how the space is being used. Mike Grant Lowe wrote: Hi Mike, Yes, d25 is a clone of d24.
