Like some basic internal drive frame w/multiple mounts from a PC, get a few and hook them together and build a box around it. Or just get a big PC case, looking for "10 bay tower" brings up a few options in the $50-100 range. Might be able to jam in more drive bays internally as well. 5 in 3 enclosures are your best bet here. They fit 5 drives in the space of 3 5.25 optical drives. I've seen cases that fit 10 or 12 optical drives, so there you've got 20 drives. Newegg has a CD duplicator case that is 12 5.25 drive bays and a power supply, and not much else. If you can figure out a controller for that many drives, you can make it work.

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.

Putting multiple slices from the same vdev wouldn't be so terrible if you're using an SSD. However, I really doubt anyone is bothering to put ZFS and migrating lots of data from an array of SSDs at present.japtor posted:I was going to suggest something homemade as well, albeit not entirely so like this one Although if someone is making homemade drive rack setups I suppose $300 is out of their budget to physically protect and secure their data and just getting a bigass n-bay tower case on the cheap is more appropriate. However, if you're going to buy a new case and a few 5-in-3 enclosures, the cost will be very similar to the Norco case. Then again, few people are willing to put a 4u rack in their bedrooms...

Goon Matchmaker posted:I ran into a weird frustrating hair pulling issue with my H340 last night. I setup freebsd 8.0 with zfs and installed samba. When I went to copy files to the H340 they transferred at 14MB/s for about 2 seconds and then my network promptly crashed. Figuring it was just some kind of strange FreeBSD issue, I formatted and installed Ubuntu 9.10. Same thing. Turns out there's something about the NIC in the H340 that causes my switch to completely flip out. I haven't narrowed the exact conditions down but just having the H340's nic plugged into my switch can cause my switch to go apeshit. I've since ordered a newer switch (mine is an old gigabit switch that doesn't support jumbo frames) and an Intel pci-e nic for the thing. Hopefully that remedies the problem. Fixed this by replacing the switch. My old D-Link 1080D was ancient anyways.

I've been wondering why there isn't a FUSE filesystem or something that can take a bunch of directories, manually organized into pools by physical separation, and do something like BeyondRAID. Like, If I had two 500GB drives and one 1TB drive I could mount them, point the FUSE filesystem to 3 directories and it automatically creates files which are translated into 500GB of effective RAID-5 and 500GB of effective RAID-1 as one large pool. Then, if I add another 500GB drive I could make another pool and it would automagically turn that RAID-1 into RAID-5. I'm sure there are a million pitfalls, but the ability to arbitrarily add storage from anywhere as simply as allocating a big 100GB file (or many smaller files) on any storage device anywhere would be freaking amazing. Got a 1TB drive on 10Mbps ethernet 2 miles away? Does it already have 400GB of porn on it? Tell your abstraction layer to use 600GB and go for it. sixide fucked around with this message at 14:39 on Dec 5, 2009 |

One thing that I love about WHS is that all the data on the drives is just NTFS, no special striping or weird filesystem. If WHS kills itself, then I can just pull the drives and restore the data from each drive manually without doing any crazy data recovery. I've been looking at unRAID as a replacement for WHS, if I ever choose to do so. From what I understand, unRAID works in a similar fashion to WHS, where you just throw drives at it and it just fills them up with data. If you pull a drive from an unraid system, cant aht drive be read by anything reasonable?

I have to know something about mdadm before I get started and everything else seems to assume you have blank volumes when creating your raid. I have a 1TB drive I'd like to RAID-0 to a new 1TB drive, but I am afraid that mdadm might corrupt or ruin the data on the original drive. Does the mdadm process automatically copy over this data to the new drive? Or should I do something else first?

I’m looking for some advice to share my media files across various devices. Here is the current situation: Living Room - Mac Mini serving as a HTPC using Plex (XBMC branch for OS X) with a DROBO serving as DAS via firewire. It is connected directly to a Linksys WRT54GL router. Room A - Mac Mini with Plex. Connected to the network with 802.11g Room B - XBOX360. Connected to the network with 802.11g Room C - Desktop PC with XBMC. Connected to the network with 802.11g Room D - PS3. Connected to the network with 802.11g Currently, only the Living room machine has access the media via a firewire connection to the Drobo. I just really want the other machines (and their connected HDTVs) in the network to be able to get to these files as well. My goal would be to have multiple machines streaming x264 720p content without a hitch. Is it even possible to stream high-bitrate content wirelessly? I have the budget to roll a custom NAS server if necessary, but would prefer an easy ready-NAS setup such as a DNS-323. Edit: After reading through this thread and some reviews on smallnetbuilder, I'm thinking about going with a D-Link DNS-321 for NAT and a Netgear MoCA which in testing seems like it could handle multiple HD streams. I'd then religate the DROBO to redundant backup. Does this seem like a reasonable setup? Not That Into You fucked around with this message at 00:31 on Dec 8, 2009 |

After my last debacle with using a lovely atom and USB drives, I have decided to do a proper NAS. Here's my hardware: 1x ASUS AT3N7A1 (Atom 330 + ION) (4GB of ram) 1x SANS Digital TR8M-B 4x WESTERN DIGITAL WD15EADS 1.5TB eventually I'll add a second TR8M and spread the pool to it, I think I want to grow to a second TR8M before growing each TR8M to 8 drives (maybe 2TB drives will fall in price). The reason it's an ION is because it's also going to be a MythTV backend. I already have a AT3N7A1 acting as a diskless Myth frontend (needs ION for MythVideo playback), and it's very silent with no hard drive.

Right now I am using a setup with USB drives on a raidz pool (it works but if one of the drives shits itself (gently caress you seagate 3rd RMA on the same loving drive) it just becomes completely unresponsive and doesn't print out any errors thereby making GBS threads itself completely (and it corrupted the entire pool once)) it nets me about 20-35MB/s over NFS which is pretty decent. I hope it'll net me closer to 60 with eSATA and port multiplicamacation, and then closer to 80 with two enclosures. But I have no hard evidence that any of this will happen, then again, I don't expect to be saturating Gbps either, I just want cheap (power requirements and cost wise) storage because Puerto Rico has ridiculous electricity costs. edit: also on the new array I will go btrfs because the data in the array is relatively worthless to me (it's a glorified PVR and some cloned VMs) so I can play with a new FS without worrying too much. edit2: ooooo, changed my mind, gonna use my current motherboard/enclosure for the storage and getting an ASUS EB1012 as my frontend, same motherboard on a tiny EeeBox package (I just have to extirpate the 250GB hard drive so it's even quieter). deimos fucked around with this message at 02:07 on Dec 8, 2009 |

If you pull a drive from an unraid system, cant aht drive be read by anything reasonable? I know nothing on the specifics, but I know you cant just read it in windows as it's a Reiser filesystem which is linux specific. So yes you can read it from outside the array, but it would need to be a linux friendly system, or just another rollout of unraid if you're like me and have never messed with linux. I currently have a mix of TB, 300 and 500GB Drives like you were thinking of doing and it works great. I plan to add in one more TB drive to max out my slots and then slowly purge out the smaller drives and replace them with new ones. I'd recommend the Unnoficial wiki on Unraid's website as it's maintained by it's users and answers a lot of common questions.

Can someone recommend a new case for my fileserver? It's an ubuntu server, and I've got 8 drives in it now - 2x80GB in RAID 1 for the system, and 6x1.5TB in software raid 5 (mdadm rules) for storage. I've finally realized I have them packed in way too tightly, and the temp is way higher than I'd like. I really liked what I saw of that Enlight SR-506, although I'm a bit disappointed it doesn't come with those hot swap bays. I found them for $40 online so I'd be willing to dish out for two of them (of course I wouldn't put the 80GB drives in since they're IDE, and it looks like I can put them in the 5.25 bays with the adapter it comes with), as long as I can just make the drives hot swappable by doing so - is there any special hardware/software configuration needed in order to do that? Or will ubuntu just support it if I use the hot swap bays?

Get two sets of the 5.25" to 3.5" brackets and you're set. I have six seagate 1TB ES.2 drives in it, and with the stock cooling they are cool to the touch. $49.99 at Fry's if you have one nearby.

Time Machine backups are working great, but I can't connect normally anymore to browse my shares. It shows up under SHARED in Finder, but when I try to browse, I get Connection Failed, with a "Connect As" button, which doesn't do anything. Any ideas? Edit: I can also connect open up the FrontView admin fine.

Just destroyed and rebuilt my ZFS pool. I was stupidly using four 1TB disks with no mirrors, which I believe would be the equivalent of running a RAID-0 "scary raid." Now I have a 2TB pool with a mirror of each disk. But I'm trying to make sure I have a clean upgrade path. Let's say I slowly want to replace those 1TB with 2TB disks, I can just replace the mirrors one at a time, right? There wouldn't be any issue having a mirror comprising a 1TB and a 2TB right? It's just that it will simply not be able use the full 2TB until I replace the other 1TB, correct?

I've been using Rivet to share media from my mac to my 360 and it's worked beautifully. If I'm going to get an Acer Revo to use as a media PC, is there any advantage to using something like the ReadyNas Duo versus just hooking up an external drive to the Revo over eSATA? Would it depend on what OS I ran on the Revo? I'd want to run a bittorrent client, squeezeserver, and DLNA server on either one, as well as being able to back up to it using Time Machine and some kind of automated copy on my wife's laptop. For now, the media PC and my router would be right next to each other, so I can do either one.

lilbean posted:You can definitely replace them one at a time, but you'll only see space increases when a pair of mirrored disks is upgraded. So if you have 4 1TB disks in two mirror vdevs and replace one disk nothing will change. But when you pop the second in, you'll have your extra terabyte (or whatever). Thanks, that's exactly what I figured. It's blowing my mind how great ZFS is. I just wish there was a way to shrink the number of disks in a pool without rebuilding it. I know it's on the todo list, but that would make ZFS completely perfect to me.
