[zfs-discuss] zfs+nfs: scary nfs log entries?
I have a zfs dataset that I use for network home directories. The box is running 2008.11 with the auto-snapshot service enabled. To help debug some mysterious file deletion issues, I've enabled nfs logging (all my clients are NFSv3 Linux boxes). I keep seeing lines like this in the nfslog: br br pre Wed Aug 19 10:20:48 2009 0 host.name.domain.com 1168 zfs-auto-snap.hourly-2009-08-17-09.00/username/incoming.file b _ i r 0 nfs 0 * /pre br Why is my path showing up with the name of a snapshot? This scares me since snapshots get rolled off automatically...on the other hand, I know that the snapshots are read-only. Any insights? br br Blake -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

What about the new flash drives Andy was showing off in Vegas? Those looked small (capacity) - perhaps cheap too? How much of an issue does the random write bandwidth limit have on a slog device? What about latency? I would have thought the write traffic pattern for slog io was more sequential and bursty.

I'm trying to figure out what's involved in determining and switching modes, why you'd want to switch them, what cards support which modes, which solaris drivers support which modes, u.s.w. The answer may be very simple, like ``the driver supports only IR. Most cards support IR, and cards that don't support IR won't work. IR can run in single-LUN mode. Some IR cards support RAID5, others support only RAID 0, 1, 10.'' Or it could be ``the driver supports only SR. The driver is what determines the mode, and it does this by loading firmware into the card, and the first step in initializing the card is always for the driver to load in a firmware blob. All currently-produced cards support SR.'' so...actually, now that I say it, I guess the answer cannot be very simple. It's going to have to be a little complicated. Anyway, I can guess, too. I was hoping someone would know for sure off-hand. Hi Miles, the mpt(7D) driver supports that card. mpt(7D) supports both IT and IR firmware variants. You can find out the specifics for what RAID volume levels are supported by reading the raidctl(1M) manpage. I don't think you can switch between IT and IR firmware, but not having needed to know this before, I haven't tried it. James C.

Thanks yes and appreciated here The benefit to running ZFS on a 64-bit OS is if you have a large amount of RAM. I don't know what the breaking point is, but I can definitely tell you that a 32-bit kernel and 4GB ram doesn't mix well. If all you are doing is testing ZFS on VMs you probably aren't all that worried about performance so it really shouldn't be an issue for you to run 32-bit. I'd say keep your RAM allocations down, and I wish I knew what to tell you to keep it under. Hopefully someone who has a better grasp of all that can chime in. Once you put it on real hardware, however, you really want a 64-bit CPU and as much RAM as you can toss at the machine. Sounds sensible, thanks for common sense input. Just the little I've tinkered with zfs so far I'm in love already. zfs is much more responive to some kinds of things I'm used to waiting for on linux reiserfs. Commands like du, mv, rm etc on hefty amounts of data are always slow as molasses on linux/reiserfs (and reiserfs is faster than ext3). I have'nt tried ext4 but have been told it is no faster. Whereas zfs gets those jobs done in short order... very noticably faster but I am just going by feel but at least on very similar hardware (cpu wise). (The linux is on Intel 3.06 celeron 2gb ram) I guess there is something called btrfs (nicknamed butter fs) that is supposed to be linux answer to zfs but it isn't ready for primetime yet and I can say it will have a ways to go to compare to zfs. My usage and skill level is probably the lowest on this list easily but even I see some real nice features with zfs. It seams taylor made for semi-ambitious home NAS. So Brian, If you can bear with my windyness a bit more, one of the things flopping around in the back of my mind is something already mentioned here too.. change out the mobo instead of dinking around with addon pci sata controller.. I have 64 bit hardware... but am a bit scared of having lots of trouble getting opensol to run peacefully on it. Its a (somewhat old fashioned now) athlon64 2.2 ghz +3400/Aopen AK86-L mobo. (socket 754) The little jave tool that tests the hardware says my sata controller wont work (the testing tool saw it as a VIA raid controller) and suggests I turn off RAID in the bios. After a carefull look in the bios menus I'm not finding any way to turn it off so guessing the sata ports will be useless unless I install a pci addon sata controller. So thinking of justs changing out the mobo for something with stuff that is known to work. The machine came with an Asus mobo that I ruined myself by dicking aournd installing RAM... somehow shorted out something, then mobo became useless. But I'm thinking of turning to Asus again and making sure there is onboard SATA with at least 4 prts and preferebly 6. So cutting to the chase here... would you happen to have a recommendation from your own experience, or something you've heard will work and that can stand more ram... my current setup tops out at 3gb. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Re: [zfs-discuss] How to diagnose zfs - iscsi - nfs hang
I'm having a very similar issue. Just updated to 10 u6 and upgrade my zpools. They are fine (all 3-way mirors), but I've lost the machine around 12:30am two nights in a row. I'm booting ZFS root pools, if that makes any difference. I also don't see anything in dmesg, nothing on the console either. I'm going to go back to the logs today to see what was going on around midnight on these occasions. I know there are some built-in cronjobs that run around that time - perhaps one of them in the culprit.

Re: [zfs-discuss] How to diagnose zfs - iscsi - nfs hang
I am directly on the console. cde-login is disabled, so i'm dealing with direct entry. Are you directly on the console, or is the console on a serial port? If you are running over X windows, the input might still get in, but X may not be displaying. If keyboard input is not getting in, your machine is probably wedged at a high level interrupt, which sounds doubtful based on your problem description. Out of curiosity, why do you say that? I'm no expert on interrupts, so I'm curious. It DOES seem that keyboard entry is ignored in this situation, since I see no results from ctrl-c, for example (I had left the console running 'tail -f /var/adm/messages'. I'm not saying your are wrong, but if I should be examining interrupt issues, I'd like to know (I have 3 hard disk controllers in the box, for example...) If the deadman timer does not trigger, the clock is almost certainly running, and your machine is almost certainly accepting keyboard input. That's good to know. I just enabled deadman after the last freeze, so it will be a bit before I can test this (hope I don't have to). thanks!

[zfs-discuss] making sense of arcstat.pl output
I'm using Neelakanth's arcstat tool to troubleshoot performance problems with a ZFS filer we have, sharing home directories to a CentOS frontend Samba box. Output shows an arc target size of 1G, which I find odd, since I haven't tuned the arc, and the system has 4G of RAM. prstat -a tells me that userland processes are only using about 200-300mb of RAM, and even if Solaris is eating 1GB, that still leaves quite a lot of RAM not being used by the arc. I would believe that this was due to low workload, but I see that 'arcsz' matches 'c', which makes me think the system is hitting a bottleneck/wall of some kind.

Re: [zfs-discuss] making sense of arcstat.pl output
I think I need to clarify a bit. I'm wondering why arc size is staying so low, when i have 10 nfs clients and about 75 smb clients accessing the store via resharing (on one of the 10 linux nfs clients) of the zfs/nfs export. Or is it normal for the arc target and arc size to match? Of note, I didn't see these performance issues until the box had been up for about a week, probably enough time for weekly (roughly) windows reboots and profile syncs across multiple clients to force the arc to fill. I have read through and follow the advice on the tuning guide, but still see Windows users with roaming profiles getting very slow profile syncs. This makes me think that zfs isn't handling the random i/o generated by a profile sync very well. Well, at least that's what I'm thinking when I see an arc size of 1G, there is at least another free gig of memory, and the clients syncing more than a gig of data fairly often. I will return to studying the tuning guide, though, to make sure I've not missed some key bit. It's not unlikely that I'm missing something fundamental about how zfs should behave in this scenario. cheers, Blake -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

This Areca card is Solaris Certified (so says the HCL) and not that expensive: http://www.sun.com/bigadmin/hcl/data/components/details/1179.html 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] 24-port SATA controller options?
We are currently using the 2-port Areca card SilMech offers for boot, and 2 of the Supermicro/Marvell cards for our array. Silicon Mechanics gave us great support and burn-in testing for Solaris 10. Talk to a sales rep there and I don't think you will be disappointed. cheers, Blake This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Truly :) I was planning something like 3 pools concatenated. But we are only populating 12 bays at the moment. Blake This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] 24-port SATA controller options?
The only supported controller I've found is the Areca ARC-1280ML. I want to put it in one of the 24-disk Supermicro chassis that Silicon Mechanics builds. Has anyone had success with this card and this kind of chassis/number of drives? cheers, Blake This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
