I'm undecided on buying a NAS. I like the Synology DS413 but it's pricy and lacks some features compared to the Netgear ReadyNAS Ultra 4 (namely, RAID scrubbing and snapshots, but I guess I can cron RAID scrubbing). On the other hand I'm perfectly capable of managing some kind of DIY thing, I just don't really want to spend the time. However, the purchase price for a DIY setup would be probably half that of the above two, though the increase power usage and larger form factor might not make up for it. Anyone have an opinion? Should I just drop the cash on one of the above two and get on with my life? Or is it easier than I think to set something reliable up that I won't have to gently caress around with all the time and won't be some ugly beastly PC case? Fake edit: I could do FreeBSD + ZFS, but that requires going 64-bit with 2g of RAM...

Will the MicroServer/FreeNAS spin down drives when not in use? Will it go to sleep? Apparently the Synology stuff will hibernate at ~4 watts when not in use (and wake up automatically?) so that's sweet. I don't think I'll use this more than 1-2 times a day, so I'd like everything to spin down when not in use. Before you ask why I'm getting something I'll use that infrequently, it's because all my computers have tiny SSDs and it's a pain sharing files between them, plus I have a bunch of raw images I'd like to archive over a year (and probably back up to Amazon Glacier?).

Is that still true with "Green" drives? I assume they were rated for more start/stop cycles since the firmware is super power conservative? I was thinking green drives + the TLER fix.

At what size array do drives with a lower UER become vital? Also, based on the WD Red drive spec of 600k load/unload cycles, that's enough to sleep/wake the drive 100 times a day (every ~15 minutes) for 16 years. It seems like letting drives sleep after a few hours of inactivity shouldn't stress them much. Though, if there is a failure caused by start/stop cycles, it may impact all drives at once.

Any thoughts on the HP vs this and this? Size/noise are a concern, effort less so as long as the end result works, but I'm not going rack a DL160 for this.

My gut feeling is that if you've spend enough money to go 10gige plus all those drives and the ramdrive, you can certainly pay someone to support it for you. Why not contact iXsystems and see if they'll sell you support for FreeNAS (or a license for TrueNAS)? They seem like good people.

So what are my other options besides the HP N40L? It's been out for a while, is there a new version coming? Can I build something myself that's fanless, faster than an Atom, and has a similar sized case/similar price point?

I guess the HP is the best way to go, I'm just annoyed the CPU doesn't support all the VT and AES extensions I'm used to and would probably use. But maybe not heavily enough to really miss them. Also I've heard of people getting it for < $300 but I haven't seen it less than $320 lately. I spoke to the lead developer for FreeNAS and he complained that Atom CPUs weren't really fast enough to do ZFS over GigE and said an i3 is much better. Seems like the N40L falls right between the two?

I really want to use CIFS though. Is there anything that can be done about that? It can't all be CPU bound? Edit: All Windows clients will be Windows 7.

So I ordered an N40L and a bunch of drives. If this doesn't work out I am going to be full of such impotent goon rage at this thread. But I'm sure it will be fine. Incidentally, forum threads show enabling AIO (via loading the kernel module and building samba with that option) on FreeBSD helps a lot with samba/CIFS performance. Anyone having trouble give that a try?

I read that not all 2tb drive models are exactly the same size. If I assign the full drives to the RAIDZ array and end up having to replace one with a different make/model, there's a chance the replacement drive might not be big enough to rebuild the array onto, even if it's a 2tb drive. Should I assign less than the maximum drive size to the array just in case, or should I not worry about it?

It appears FreeBSD 9.1-RC3 can't rebuild onto a smaller drive (tested inside VMWare). Given that, what do other ZFS users do? Another ZFS question, is df the only way to find out the usable size of a pool? zpool list seems to show the total size including the size of parity drives, and zfs list shows the used and available but not the total. df shows the total, or I can just add up the totals from zfs list, but it seems odd nothing would tell me the usable size of the array? diehlr posted:I've ssh'd into the box and run the top command and not seeing any odd spikes in CPU utilization. The drive is reporting as healthy, and is a Seagate 3 TB drive. Any suggestions on tracking this down would be fantastic. I don't know if synology has "iotop", but if not that try "iostat 1". iostat will print a lot of information, but you're looking for the MB/s or KB/s under the column that looks like it's named after a drive (md0?).

Has anyone had luck getting > 8 gigs of ram into an N40L? I read some people were able to, so I picked up an 8 gig stick of KVR1333D3E9S RAM but I can't get both the 2 gig that comes with it and the 8 gig to work together. The BIOS shows both sticks of RAM with the correct timings and everything, but POST only counts up to 2 gigs with both installed. Installing one at a time works okay. I flashed that crazy AHCI enabling BIOS but it didn't make any difference. Any suggestions?

Krakkles posted:Dumb question: If I stick my four 2TB drives in my N40L, can I install my OS on those drives? Or do I need to somehow get an SSD or something to install on separately? You can, but there is also another internal SATA and USB port you could use for a boot drive (flash drive, SSD, SATA->CF adapter, etc).

You can install FreeBSD (and I assume FreeNAS/NAS4free) in vmware onto a USB stick if you don't assign the VM a hard drive and just plug in the USB stick. The installer will see the USB stick as the only HDD and will work just the same as it would on a hard drive. Once it's installed just plug the USB stick into the N40L.

I don't know enough about the process/NAS4free/whatever to help you, I'm telling you this worked for me. Edit: I've also had trouble with 64-gig memory sticks, Windows doesn't really like working with them. Never had problems with 8- or 16-.

Yeah, copying files isn't enough. I believe it needs an MBR with a bootable partition and boot loader installed. Fortunately doing it through the freebsd installer will do all that for you, though it's slower writing things file by file as an installer will do than as large blocks like an imager will do. Oh well, you only should need to do this once.

One of my NIB WD Red drives failed right out of the box. I plugged it in and copied a big file to it which worked fine, but then I ran a smart "long" test and it failed within a few minutes. I re-ran the test to be sure and the drive stopped responding completely. Back in the box it goes. If you're setting up a new array and have the time, test the drives before you put anything on them. It will save you headaches down the line.

Wasn't there a data corruption but that was just fixed in btrfs? I'm not sure I'd trust it yet. My N40L has ECC RAM in it and the BIOS is set to Parity: Auto but MemTest86+ says ECC: Disabled. Should MemTest86+ recognize the ECC?

Can't you replace each drive one by one with a larger drive and let it resilver, and at the end it will grow the filesystem to the new drive sizes? Also I don't think you want 111 for permissions, that would deny read and write access to everyone.

I tried with and without extended attributes and alternative data streams enabled. If you run smbd with all the debugging flags enabled, does it print anything interesting about that file? It's probably a lack of support for Win8 in Samba, though. Edit: smbd -i -S -d 9999 ?

I've got FreeBSD 9.1-RC3 on a N40L and I get reads of around 100mb/sec that drop down to ~60mb/second after maybe 30 seconds. I'm not sure why that is but it's possibly on the client end, my desktop is almost out of disk space.

IOwnCalculus posted:I haven't yet been able to get a good enough look at the console before it reboots to figure out what it's spitting up but I think it's some form of segfault / kernel panic / whatever the poo poo goes for a BSoD in Solaris-land. I think there was a bug like this recently found in FreeBSD believed to also be in Solaris. See here. The long and short of it is that old versions could write corrupt metadata that caused a panic on delete. The fix was to backup all of the data and re-create the pool.

IOwnCalculus posted:That sounds a lot like it. I may just live with it for the time being since this is literally the only file with the problem (so far), and the amount of space it takes up is completely negligible. Oh, sorry I wasn't clear. Apparently you can make a backup from the data as reading it won't cause an error. You just need a temporary location for the data while you destroy and re-create the array. Of course if you don't have another array with at least that much free space that doesn't help you. Maybe you can unmount the drives and correct the issue with a hex editor, if you're feeling brave.

For 6 drives there's an adapter but I forget the name. The PSU isn't that powerful though, I don't know if I'd trust it to run 6 drives but people have reported success. You'll also want 8 or 16 gigs of memory (I bought Kingston ECC).

Comradephate posted:I can't seem to find anything more recent than early 2011. I imagine ZFS is significantly slower at some tasks (since it performs checksuming of all (meta-)data) and faster at others (resilvering only allocated space). The fact that the filesystem, RAID, and volume management are all united would probably save you time, though.

I haven't had any problems with the Boadcom NIC in my N40L (it's not a realtek). It's not as good as an Intel but it's likely going to work fine for most people. Most if not all HP servers ship with Broadcom cards and run fine with FreeBSD. If you were trying to do line rate gigabit worth of 68 byte packets I'd say get an Intel, but that would be a terrible scenario for a NAS.
