friendship waffle posted:wouldn't this kill performance completely Yup. Block allocation is completely written to assume that your devices are one spindle iirc. You also have to be extremely careful about not loving up where your disks land so you don't wind up doing something braindead like putting 2 slices of the same vdev on the same spindle, but that is true when you're doing any kind of controller splitting, etc. It's listed in the docs as being for debugging purposes only.

necrobobsledder posted:Umm, every other review on Newegg says the fans are loud as gently caress. But really, if it's that loud I'll have to reconsider it for placement in the garage in a 12U enclosed rack. I'm not sure what a good set of fans to replace the Deltas would be considering airflow is a big, big concern with so many drives. It's a server chassis made for a datacenter. "Quiet" isn't on their mind. Delta fans are awesome fans, but I wouldn't put this in my house. Garage, sure.

necrobobsledder posted:It's a really low quality case that I wouldn't put in a datacenter unless I'm doing some crazy low-cost storage project is the thing, and there's a bedroom next to my garage, so I wouldn't want something so loud you can hear it easily outside the garage even. I just wish there was a better option for 12+ drives in a box for home users besides some rackmounted monstrosity like this, but given how much data it potentially holds, I'll have to treat it like a professional datacenter setup. Out of curiosity, what specifically is low quality about that case? It appears to be metal, metal, metal, some plastic, some Delta fans, and a power button? Plus, if your walls are so hollow why not insulate them? It will add value to your home and you will sleep better at night. And if you don't want a datacenter-esque case, why look at rackmounts at all? I'm sure you could build a really bitchin full tower with 12+ drives in it.

necrobobsledder posted:The thickness of the metal (merely "adequate") along with the flimsiness of the drive trays was mentioned in a lot of reviews I've read, along with the backplanes having the molex connectors hot-glued on there poorly. I know I shouldn't expect much for a $340 4u case, but I want to feel like my data is physically sound at least. The poster I quoted said that he could hear the fans in the next room over, and given how sounds bounce in a garage, it'd be awful. I'm not sure what you expect. Something like a SuperMicro chassis for apparently $1800* also sounds like a jet engine, the drive caddy's are a thin finger-bendable aluminum, and the backplanes tend to come with at least one or two dud/flaky ports per 4-8 bought. Thumpers have very sturdy drive caddy's, but are deafeningly loud. A Xyratex enclosure is certainly sturdy and "well built", likely not to be any dead ports, and screaming loud. Get ready with your credit card though, because it's going to cost you. If you want your data to be "physically sound" then it's time to get spendy on your RAID card (LSI only, really) and motherboard. If you want cheap or quiet you're looking at non-rack mount, and not dense. Get yourself some rack shelves and long SAS expander cables to link your chassis' together. * http://www.8anet.com/ShowProduct.aspx?pid=7259 , http://rdr.to/0mS , wtf $1800? Is there a motherboard/cpu/ram in that I am missing? I guess 3x1800W power supplies.

Just chiming in to say that Synology support just RMA'd my 4 year old (3 year warranty) DS1815+ with no questions asked. Unit started doing constant raid scrubbing (`cat /proc/mdstat` showed "the big volume" resyncing constantly), hanging file services, and eventually failing to stay on after pressing the power button. Told them this and the initial reply back was them mailing me a new unit. A+ would spend far too much money again. No BS, no "have you tried not having disks" etc.

Droo posted:Sounds like you just barely made the 4 year cutoff for the C2000 bug - they extended the warranties of all the XX15+ models by a year as their response to it. Ah, I'll be damned. I vaguely recall the C2000 bug and had completely forgotten my Synology was affected by it. I am in fact rounding up a little over 3.5 years to 4 so that would explain it. I guess I should expect to replace this unit in 3 years or is the hardware bug fixed? Google is yielding lots of teeth gnashing and pre-recall "everything is fine" notices from Synology.

Transferred the disks over 1 at a time into their same slots, booted up, raid resync'd in ~8ish hours. Now I am back doing file services again, time machine on my laptop is happy to have a target again and the synology is sync'ing up to B2 as we speak.

spog posted:Good suggestion and appreciated, but my tinfoil hat prevent me from using cloud storage for my personal docs. Your financial documents are probably the least important thing on your synology which is why I didn't mention them.  For your tin foilness: The B2 system does encryption locally then uploads. It's on you to maintain the key. I would suggest printing it out and storing it in a safe deposit box along with a copy of your home owners/renters insurance policy. Glacier was always so flaky for me on uploading a zillion small documents, I'm glad it's working for you.  That being said I think upgrading the Synology firmware fixed most of that, but by then everything was in B2.

KOTEX GOD OF BLOOD posted:So my Synology units are only getting accessed for a couple hours 2 or 3 times a week. The rest of the time I'd like to have the drives spun down and the units consuming a minimum in power, mostly for wear and tear reasons. I tried the "advanced HDD hibernation" mode, but it takes ~20 seconds to start up and respond when you try to access them – fine for me but not for family who will get errors when they try to access content. Whats the best way to minimize wear and tear / power use while still having the units be responsive? What is erroring out so quickly? Ours is mounted video NFS for plex, afp on macs, and smb on windows all the time and nothing errors out. It just stalls while the disks spin up.

Avian Pneumonia posted:Is there any advantage to getting an external NAS and NAS drives versus getting a few extra traditional internal hard drives and setting them up with a plex server on a raid array on my existing desktop computer? Push button configuration of your array, often push button configuration for expansion. You also suddenly get a always online target for things like Mac Time Machine backups if that's something of interest. I do just use my NAS as a file server though, it doesn't do anything else. (So: Windows, Apple, and NFS file sharing. It beacons and provides time machine backup target, I've used it for its NVR capability, music sharing, that sort of thing. Nothing "compute intensive.")

Simone Poodoin posted:Interesting, so judging by this the network is fine and the slowdown would be somewhere else Correct. I would run `top -c` on your unraid machine while copying a massive file. See if any single cpu thread is pegged out. `iostat -x 2` (ignore the first output always) will show you disk subsystem stuff. Open a few terminals and get this stuff going. Is the problem when reading, writing, or both? Writing points to disk subsystem slowdowns, cpu parity calculation (unlikely), or smb implementation being poor one one side or the other. Disk subsystem could be a single slow drive dragging down your speeds.

If you want your  on the VPN then -D 12345 on the ssh connection and configure your torrent client to use a socks proxy on localhost:12345. Forget the -R junk.

For more information lookup OPAL and TPM. The TPM will be told "generate a key" - this becomes the MEK. The method to authenticate to the TPM will vary by implementation, but generally you tell it "this is my password" and it will run it through a secure one way hashing function like SHA2 or scrypt and store the result. Other methods are for it to gather a hardware inventory and refuse to unlock unless it matches. In its default mode the TPM isn't authenticated. With a TPM the MEK should never leave the TPM. If a standalone KEK is used then it is done using a PBKDF function to convert your password into a key.
