Re: [zfs-discuss] zfs performance cliff when over 80% util, still occuring when pool in 6
Final rant on this. Managed to get the box re-installed and the performance issue has vanished. So there is a performance bug in zfs some where. Not sure to put in a bug log as I can't now provide any more information. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

[zfs-discuss] zfs performance cliff when over 80% util, still occuring when pool in 60% ?
Ok had a pool which got full - so performance tanked. Ran off and got some more disks to create a new pool to put all the extra data. Got the original pool down to 60% util, but the performance is still bad. Any ideas on how to get the performance back? Bad news is that the pool in question is rpool. And this is really starting to effect my productivity on the box. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Re: [zfs-discuss] ZFS + OpenSolaris for home NAS?
It depends on what your doing. I got a AMD Sempron Processor LE-1100 (1.9Ghz) doing NAS for mythtv and seems to do ok. If the board you quote is what your getting I think it is 64bit chip - intel site says its a Atom 330. Solaris will should use all its cores/threads - intel have added a load of code to opensolaris not sure if Atom stuff was in it. Think your out of luck for PCI SATA cards - not seen anything good about it. Sil hardware is buggy, but its got the driver support. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Re: [zfs-discuss] Replacing Devices in a Storage Pool
You do not waste the new space zfs seems to always work of the lowest device - so when you replace the disks with larger ones it increases the mirror size to these new drives as thats the new smallest drive.

Re: [zfs-discuss] ZFS Home NAS - Configuration & Questions
Ok I am not an expert - just done some playing about. Option 1) I have done this - i had 4x300gb disks and one more in the post, i could not wait to build my raidz2 so i used a 73gb which was spare - what it gave me was a raidz2 pool of 5x73gb. The warning is there to ask you if you really want to lose all the space. zpool replace 73gb 300gb disk worked fine and i went to a pool with 5x300gb Option 2) Done this too with some 18gb mirror and a 73gb mirror, seem to work fine no performance drops. I guess the stripe will only last for 18gb then drop to a single disk performance Option 3) Not sure about this one, not had chance to play with this feature Hope this helps a bit Also see http://www.solarisinternals.com/wiki/index.php/ZFS_Best_Practices_Guide This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Re: [zfs-discuss] 8+2 or 8+1+spare?
Your data gets striped across the two sets so what you get is a raidz stripe giving you the 2x faster. tank ---raidz --devices ---raidz --devices sorry for the diagram. So you got your zpool tank with raidz stripe.

ok if its just storing stuff raidz2 is probably the best use of space. raidz2 on 5 disk and one spare - this can take 3 disk failing before you lose your data. The three strip mirror will give you nice performance but from the sounds of it you don't need it.

[zfs-discuss] ZFS layout for 10 disk?
got a 12 disk system - all 18gb 2 mirror for boot, now what to do with the rest? The storage is to be used for user space, web stuff and to store anything else (dump for data). I could do 5 mirrors, but thats a wasting quite a bit of space. Was thinking about raidz2, as its almost as reliable and better for space. Should i do 9 disk raidz2 with a spare, or could i do two raidz2 to get a bit of performance? Only done tests with striped mirrors which seems to give it a boost, so is it worth it with a raidz2 of this small size?
