DrDork posted:Starting out with different sized disks in RAID2Z isn't bad, but it is quite inefficient, since as I'm sure you've noticed, you only get usable space commensurate with whatever the smallest drive you have is. Thanks so much! Do you possibly have an answer to the permissions problem I asked about?

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.

Megaman posted:One more question, when ZFS is started up I've noticed that it just sits at a question prompt that anyone is allowed to access physically on the server itself. Should I be selecting "shell" then logging out of that account? How does everyone else handle post boot security on the server cli?

I'm not sure about resilvering, but that sounds like what I'd need to do if I can't expand the pool by physical disks. What is the reason for that limitation?

5TB disks? Seriously? Good god I can't imagine the rebuild times on something like that. With disks that large is ZFS / raid-z pretty much the only feasible redundancy path?

I have to wonder if something like triple parity would even be useful at that point. I'm already re-doing an array of 750gb disks into 10x3TB disks in raid6 + 1 hot spare (21TB usable space), and that's just betting on having up to two disks fail with 1 standby to buy me more time.

Why not do Z3? Seems like that might be better than hoping you don't have two more failures during the rebuild. Also, for what it's worth, if you're like me and turn on dedup without realizing just how much RAM it needs (roughly a fuckton), this process seems to be working pretty well for me to undo the damage. Specifically: code:

![]() This is me, switching from 4 Seagate Baracuda 3TB to 4 WD Red 3TB with the help of a lot of scrapped SATA cables, SATA power adapters and a stronger PSU (with 6 SATA power cables) ripped from the heart of my desktop PC for the duration of this operation. I got the Seagates from external USB 3.0 cases, which miraculously cost 5€ less than the bare HDD itself. But since it has shown really bad noise, a high power consumption and thermal profile I decided to switch to the WD Red, which according to SPCR is one of the most silent and power saving 3TB drives. Thank god for free return after 14 days due to right of withdrawal ![]() What I'm trying to build is a silent NAS, which made me dump the HP N40L due to its quite noisy PSU fan. So I switched to a crappy midi-tower, 400W PSU, Intel G630T and the cheapest MB with 6+ SATA ports, 8GB ram and 2 silent 120mm fans. I really like this setup over the N40L as it is not only stronger (about 4 times in CPU) but also only costs ~25% more and is scalable (Socket 1155 and Ivy Bridge compability, 4 ram slots, tower for more HDDs).

Anyone hosting Windows 8 roaming profiles on Samba shares? Any issues with that? I'm getting all kinds of weird corruption issues (the contents of \Favorites end up getting zeroed out). I haven't been able to find anything on Google that even hints that any people are using Windows 8 profiles on Samba.

I've tried with SMB1 and oplocks enabled & disabled. I tried with and without extended attributes and alternative data streams enabled. It's always the same errors and always on the same files. I started with a new profile (nothing local, nothing on server). The files are created locally (Favorites/desktop.ini), saved to the server as zero-byte files, then re-read back to the profile as zero-byte files, destroying the good/local copies.

It's probably a lack of support for Win8 in Samba, though. Edit: smbd -i -S -d 9999 ?

necrobobsledder posted:A lot of people have swapped out that fan (it's a standard 92mm fan I think). I haven't had a problem with it in my living room because it sits inside a closed TV stand. Also, I highly doubt that your machine is more power efficient than an N40L just by virtue of the 400w PSU (even a "Gold" rated 80Plus PSU can only do so well on a load average of less than 13%). Not saying it doesn't work for you, but sounds like your needs weren't quite fitting into what people buy Microservers for honestly. It's the 40mm PSU fan, not the big one cooling the case that was the real noisemaker. Switching out the PSU for a PicoPSU or something similar would've pushed it to about the same price I smashed my server together for, so I opted for the more powerful one I can scale and customize more. If it weren't for the different PSU the SPCR review said to be unnoticeable (their model at least) I would've kept the N40L though. I'd heartily recommend it for anyone who doesn't have an issue with noise.

The PSU fan is luck of the draw. Many of them, including mine, are virtually silent but a bunch are rather noisy. HP or the PSU manufacturer are probably getting fans from different suppliers with different tolerances or something.

I've been having really fucked up problems with my NAS recently. I've run SMART tests and everything on the NAS and it's all checked out OK. It runs the latest version of FreeNAS. If I'm on Ubuntu or some other Linux variant, I can access/transfer files over FTP/Samba without any issues. When I use Windows, the problems start. FTP transfers go from 100 MB/s down to 100 KB/s and constantly cuts out. File browsing via Samba is terrible. It won't always load directories/files and it will constantly get frozen on any file that I click on. Even a very tiny text file. If I want to watch a movie, I have to restart the Windows PC. And if I decide that I want to watch something else ... well, I have to restart again ... This is driving me up the wall. Any help would be much appreciated!

Is the CIFS/Samba support really as bad as people say it is? All of my computers are Windows and only 1 of them has Pro, so NFS wouldn't do me much good. Does the NAS4Free SMB implementation work any better?

Why not give Solaris/OpenIndiana and napp-it a shot? Their CIFS is kernel mode and apparently really good.

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.

I honestly don't know anymore. I stopped following the OI/Solaris thing a while ago, but napp-it is super simple to install once you have solaris/oi installed and you'll never really mess with the OS after napp-it is up and running.

Maybe the complaints I've seen scattered throughout the thread lowered my expectations, but so far (knock on wood) I've been impressed with the CIFS/SMB performance I'm getting out of my N40L. For reference, my system has 8GB ECC RAM, Intel gigabit PCIe NIC and 5x 3TB WD Reds in a RAIDZ2 on the hardware side. Software wise, I'm using N4F 9.1.0.1 rev 531 and SMB2 with AIO disabled. I have noticed that writes (and to a lesser extent reads) are bursty, but the actual transfer speeds I'm seeing are good. My read speeds from the Microserver top out around 900Mbit/s and writes will peak up near 800Mbit/s but probably average more like 600Mbit/s.

My issue with CIFS has always been one of consistency: some files will transfer at 70-100MB/s. Others at 30-40MB/s. There seems to be no rhyme or reason for this.
