From zanchey at ucc.gu.uwa.edu.au Fri Aug 15 15:46:07 2014 From: zanchey at ucc.gu.uwa.edu.au (David Adam) Date: Fri, 15 Aug 2014 15:46:07 +0800 (WST) Subject: [tech] Molmol the slightly more fileserver In-Reply-To: <53D514B5.9040207@ucc.asn.au> References: <53D54303.4050005@ucc.asn.au> <53D514B5.9040207@ucc.asn.au> Message-ID: Thanks to [SZM] for getting Debian+ZFS configured on Molmol. I won't be at the tech meeting tonight so here is what I've done in the last few weeks. The short story is that actual NFS performance on Debian+ZFS was worryingly terrible. I made some changes to Molmol over last couple of weeks. The initial ZFS setup had everything in RAIDZ. I redid the partitioning and the RAID setup as detailed on the wiki page (http://wiki.ucc.asn.au/Molmol). I also installed FreeBSD and configured an identical array (the ZFS versions in Debian+ZFS 7.6 and FreeBSD 10.0 are slightly different so I had to destroy the array each time). This is also detailed on the wiki page. I wasn't sure how to run iozone and I wanted to run some slightly different benchmarks, because I'm more interested in "real-world" tasks compared to 4k writes. I'm on holiday overseas at the moment so these aren't terribly rigorous, but I tried untarring the Linux 3.16-rc7 tarball in various ways. Firstly I decompressed it and stowed in on /tmp on Motsugo, which (I think) is RAM-backed tmpfs. Then I ran `time tar xf /tmp/linux-3.16-rc7.tar` into the various storage options. With Molmol booted into FreeBSD, it untars locally (i.e. not over NFS) in 6 seconds. With Molmol booted into FreeBSD and mounted over NFSv3 to Motsugo (using wsize/rsize=8192), it untars in about 3m32s. Increasing wsize to 32768 didn't change things much (3m26s). With Molmol booted into Debian and mounted over NFSv3 to Motsugo (using rsize/wsize=8192) performance was much, much worse: 22 minutes! For comparison, the same operation against /services (from Nortel) was 2m3s. I'm not sure why the performance is so terrible on Debian. Obviously there are lots of gaps in the matrix I haven't filled in (what's it like locally on Debian+ZFS, what's performance on the stuff mounted on Mylah like), and there's times when our network performance goes through the floor (down from gigabit to 200 megabit or so) which I haven't worked out. The other interesting thing on Debian+ZFS is a strange intersection of ZFS datasets (which are like sub-filesystems, I suppose) and NFS mounting. Create a ZFS pool with a dataset (/space) and a dataset within it (/space/scratch), Mount the dataset /space over NFS (`mount -t nfs -o wsize=8192,rsize=8192,vers=3 molmol:/space /mnt` or so). The contents of `/mnt` will be `/mnt/scratch/`, but if you write any data into `/mnt/scratch/` it doesn't end up in `/space/scratch`. Instead, it's written into a subdirectory in `/space` called scratch, which doesn't appear unless you destroy the /space/scratch dataset. It would be worth seeing whether this happens under FreeBSD as well, but I don't think it does. That would definitely need to be sorted out before we used Debian+ZFS on Molmol. Hopefully that made some sense.

Mobo - Asus good, Gigabyte less so (imo). RAM - the old machine has 8GB of DDR3. Maybe it's worth testing that RAM in another machine for a week to see if it's any good before we go buying more? GPU - good. I'd go for whichever of those has the best cooling and will cope best with the dust buildup you get in UCC machines. HDD - use the existing 1TB disk in the machine. There's nothing wrong with it and we're quite a long way from filling it still. Case - definitely use the old case. We were careful when we got catfish and combtail to get cases that we could use in future machines. It probably wants a good dusting, but is otherwise all good. The existing case has been modified for our security cables too, and the ability to make cases work with security is a criteria you need to look at if ever you're buying cases for UCC. I check that the mobo you specced also has all the correct headers for the front panel connector of the existing case, so all good there. If you need any parts for it they should be in a box in the machine room. PSU - use the existing one unless it doesn't have the right connectors or not enough power. The bag of connectors for that PSU was kept and should be in the machine room. Optical drive - use the existing one, there's nothing wrong with it. Even if it weren't, the club now has an external DVD drive, which should be in the machine room. SSD - definitely a luxury item on windows machines where most of the login-time length is due to samba slowness. Games (including steam games) should be on the bulk storage disk on the windows machines, so not a lot of gain there. An SSD may make things faster for people with cached profiles, and maybe the odd program I guess. Eh, all the other machines have them, may as well get one. The only other thing I think we should get is a new screen for Catfish. The current one is a 21.5" Samsung that really is a bit long in the tooth for the machine it's on. I'd suggest another Dell U2412, or maybe it's time the club splashed out and got a 3D screen with glasses. Whatever we get, it just needs an available VESA mounting hole for security cables.

On the contrary paying $90 extra and upgrading to a 770 would be the best price point for performance however this would likely require a 550W+ powersupply, if the current one is stuffed or underpowered for the build (under 550W) then my recommendation would be to with a 650W power supply and a 770 card however for the cost of ~$110 extra ($20 extra for the 650W over the 550W and $90 to go up a card). The need for an SSD is not here nor there and can be upgraded to later if required, it's just become a standard for build that I do now and the Samsung EVO range are quite affordable. I will check the power supply and RAM when I have time this week, may need to run memtest overnight. Regards [VIJ] -------------- next part -------------- An HTML attachment was scrubbed...
