Well, this is great. My HP N40L hard locked the first time I tried to copy any real data to it (300 gig of pictures) I woke up this morning, couldn't access any files, couldn't get to the web interface and SSH wouldn't respond. FreeNAS has no information for me other than that my ZFS pool is healthy. I sure would like to know what's going on. Does anyone know I can get this thing to log somewhere else so I can see what's going on?

IOwnCalculus posted:You're absolutely on the right track there. I have this setup in concept, except that I haven't yet added a M1015 and OI/ZFS yet because I don't have any intermediary storage to migrate the data off of my mdraid array. I am passing the onboard SATA controller directly to an Ubuntu VM and picking up the individual drives that way, and performance is just as good as native...even a bit better than the old / much lower horsepower system it was on before when it was running natively on the hardware.

My FreeNAS server is getting kernal panics every time I do large file transfers. It stays up for about an hour, and then crashes with an error in the console. It's reproducible every time. Error message: Panic: kmem_malloc(32768): kmem_map too small: 1607741440 total allocated I burned FreeNAS-8.2.0-BETA2-x64.iso to a disc and then used another PC to install to a 8gb flash drive. AFAIK, this is the correct 64-bit version. My hardware is as follows: HP ProLiant N40L Microserver 2X Kingston 4GB 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10600) 5X SAMSUNG EcoGreen F4 HD204UI 2TB 32MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive 1X WD 2TB Green Drive Intel EXPI9301CTBLK Network Adapter Any thoughts?

As a general rule, any issue (with exception of the UI) you can run into with FreeNAS will be replicapable (and has already been experienced by someone else) on FreeBSD (and if the issue is related to zfs, that makes it even more likely that someone else has encountered it).

Some things say "Ohh, if you have the 64-bit version, you don't need to adjust this at all" Some are recommending I set vm.kmem_size to twice my ram, other are suggesting setting it to exactly my ram, and still others say half. As of right now, I've set it for half my ram and am copying files, and it hasn't locked up yet. I was just hoping someone who'd built a very similar system (the N40L being so popular in this thread) can give me a better answer.

Not sure if I'm going to be able to go all the way with an IOMMU setup with that little space to work with. Maybe I need to start rethinking this plan... You might be screwed on the ITX front for AMD then, I don't see any 990* chipsets in an ITX board there. Doesn't Lian Li have a slightly larger case that will support MicroATX though?

Does Hitachi do advanced RMAs? Looks like one of the drives in my server is on its way out, lots of entries from fmadm/fmdump, and SMART reports 'Impending Drive Failure'.  Funnily enough, I can still access 99% of the files on my server, it just seems my most recent downloads that I've copied over are inaccessible/throw lots of disk errors.

IOwnCalculus posted:If cost is your primary concern, and you don't get a screaming deal on a lightly used DQ67SWB3 and i5 2400 (thanks, kill your idols!) then the cheapest way to go is the AMD AM3 processor of your choice, and the Asus M5A97 board (this bad boy). AMD treats VT-d/IOMMU as an entirely chipset-based feature, so in theory it should be fine with even a shitass Sempron, though I only tested it myself with an FX-6100.

Newegg has the N40L bundled with a WD 2TB Green Drive for $289 as the shell shocker this morning: http://www.newegg.com/Product/ComboDealDetails.aspx?ItemList=Combo.895105 Sort of a hot deal? The drive is $130 by itself, assuming you have a need for it.

Ideally I could find one with an integrated GPU--last thing I need is another loud video card. It's the one that someone else suggested that I use, and the only one I've tested to confirm that IOMMU works on. Not sure if any of the integrated graphics chipsets support IOMMU. Also, while a lot of AMD's chipsets support IOMMU, the manufacturer still needs to enable it in the BIOS. IOwnCalculus fucked around with this message at 15:17 on Apr 9, 2012 |

Question on my current setup. I've got a N40L, 8gb of ram, with regular Ubuntu installed on the 250GB drive it came with and a 500GB/2TB drive for data. I'm mainly using it to run rtorrent, streaming to boxee, and data that doesn't fit on my macbook air. The ultimate plan is to get a few more 2TB drives but nothing's urgent right now. I see a lot more people using FreeNAS with the N40L. Is there any reason to transition my server over to FreeNAS instead? I'm just worried that I'll keep on buying 2TB hard drives and never come up with an intelligent, somewhat redundant system. Residency Evil fucked around with this message at 18:14 on Apr 9, 2012 |

FreeNAS has ZFS and is very loving simple to setup. However, with the current release, you can't expand the array due to a limitation with ZFS version 15 (I think in future versions you will be able to). If you don't plan on buying all 4 drives at once, Ubuntu and mdadm is fine. The only thing about Ubuntu is that is takes a bit more work/reading to setup where FreeNAS has everything in a web interface.

You can't expand a pool disk by disk with ZFS, and that will probably never change. You can add more vdevs in a stripe, or you can make bigger disks.

I'm getting pretty much the expected speeds through CIFS and NFS. However when I do rsync over SSH, I get max 5MB/s. I was searching around this morning and found this thread: http://forum.synology.com/enu/viewtopic.php?f=153&t=21212 Which is other people having the same issue. They believe it's the CPU maxing out on the encryption of the SSH protocol. When I get home tonight I'm probably going to mount my Synology box via NFS and just rsync over NFS. I'm going to try doing an rsync module first but I've been unsuccessful in getting that to work so far. IT Guy fucked around with this message at 20:23 on Apr 9, 2012 |

I'm doing an rsync copy across a remote CIFS mount with no SSH encryption and im setting 5-6MB/s on the synology. CIFS copy still is 20+MB/s while this copy is running so eliminating SSH will not correct the problem the CPU is pegged out with the checksums from rsync.  The only way around it is probably do the rsync copy from the unraid NAS with a much better cpu.

Yeah as was stated, I'm pretty sure you can't add to the number of ZFS drives in a pool. Unfortunately it's not as slick as whatever drobo does. I think what I might do is add 2x2TB drives and convert to Raid5 eventually. The thing that attracts me to FreeNAS is that everything is so simple and less of a pita than doing it manually.

Just thought I'd give another update: The port multiplier is *not* the issue - I was correct. When functioning correctly I can achieve 60MB/s writes, matching my previous back of napkin math. I've discovered that the issue occurs when I close my case side, slightly nudging some SATA cables. I am going to order some replacement cables and replace all my old SATA cables. Having said that, this does not solve the slow speed in ESXi issue. I will attempt troubleshooting on that front later, though I have a backup plan of action where I will purchase 2 LSI 2008 SAS HBAs and pass those through to the storage VM if all else fails.

Some flash drives just can't be made bootable for some reason so it might be that. e: or at least I've got two Kingston DT101 G2 8GB USB drives and none of the tools I've used in the past will make them into bootable USB drives. I've got a couple other thumb drives that work just fine with UNetBootIn, LinuxLive USB Creator, and just DDing USB images to them but doing the exact same thing with the exact same images on these drives doesn't work.

Weird. Maybe mine are from a bad batch or something because I've tried about a dozen different ISOs and at least 4 different methods of putting an image on these drives (from a variety of OSes) and it doesn't work. However all of the images and software works fine on the handful of other USB drives I have. e: Ok now it loving works. What the gently caress I spent hours with these two drives trying every piece of software from a variety of host OSes to put a variety of different images on these things with no success. Three months later and the same poo poo works fine. I've got no loving idea. At least I can not use these things for the purpose I bought them for. Other than the fact that I don't need them anymore I guess. Galler fucked around with this message at 01:03 on Apr 11, 2012 |
