Whoops I posted this in the wrong thread but anyways; So anyone here have experience with FreeNAS's ZFS replication and performance? Basically looking at 2 Nodes; 7x146GB 15K drives 1x400GB EFD Thinking about doing RAID-Z on the 7 146GB drives, ZIL 12GB, and with L2ARC 200GB; and supplying the FreeNAS appliance with 4vCPU's and 12GB ram with Direct IO to the RAID Controller. I'm looking to replicate data between the 2 nodes in 30-45 minute intervals. With Backups going to a VDP appliance. The concern I have is how much a performance impact on when Freenas takes the snap to when it replicates. I realize it is going to snap the changed data and the performance is relative to the amount of changed data but I was wondering if anyone has experience with it. Not trying to ask too much but does anyone have experience with how well FreeNas's DeDupe works? I don't think I am going to enable it but haven't toyed with it enough.

ZFS dedupe uses a fuckton of RAM. Ungodly amounts of RAM. Even for a relatively small pool like that and some very high performance L2ARC (it will put the dedupe tables there if/when it runs out of RAM) I don't think 12GB would be enough, and performance goes to utter shit if you run out of RAM with dedupe enabled. Unless for some reason you can add a lot more RAM more easily / more cheaply than adding another disk or two, don't fuck with dedupe.

On FreeBSD the recommended solution is to use compression but not dedupe, especially if you have a good CPU. Last I checked (and this was a while ago) the dedupe table was not limited to any size, so no matter how much RAM you had it's possible you could exhaust it and end up with a panic. The recommendation was 1G/TB + whatever else you use for the OS, cache, apps, etc, but there was no guarantee.

I'm hopping off the NAS train, and I've got a Synology 411j with 4 1TB Sammy Spinpoints in it I'm looking to sell. If anybody is interested PM me, I'll have the thread up in SA mart tonight.

I built my own NAS so I gloss over posts here about bought appliances, but now my mom is in the market for one, so here I am. She estimates she only needs a terabyte, but I'll give her two to be safe. I'm thinking something with two drives for RAID, and then I'd like to back it up with something like Crashplan. Any suggestions on what I should be looking at?

kiwid posted:This + 2x 2TB Reds + This. Im about to order that exact NAS for a similar use case, but I noticed that theres a newer and 30 cheaper 214se out already. It has half the ram (512 vs 256 MB) and the CPU is 400 Mhz slower, so I assume the "old" but slightly more expensive 213j is the way to go even though 802.11n will be the bandwidth bottleneck?

Does anybody run Crashplan on their Synology? E: I see there are instructions on the Crashplan site even though it's unsupported, just looking for any first hand accounts of how well it works.

I've never touched the se version so I can't quite answer that. If all you're doing is just long-term storing files and maybe streaming movies/music, I'm sure it'd be fine.

Speaking from experience with a massive library on Crashplan (though not on Synology), the client does like to use a good bit of RAM - I've actually had to increase it from the default self-imposed maximum of 512MB on my server. I would probably go for at least the 512MB version if you are going to run Crashplan on it.

Here is a pretty good review of the DS214se it looks like. Although be mindful of this ^^^

For some reason I glossed over this thread before buying a NAS but oh well. In any case please let me know if I fucked up way too bad. About a month ago my external started acting really funny. Since I've got a lot of irreplaceable thing on there I ended up sort of panic-buying the Synology 414j with 4 1 TB drives. Formatted using the Synology method for maintaining integrity even with two discs failing. Ended up costing around $800 or $850. Didn't know about Crashplan at the time but I've started uploading to them as well. I'm not running Crashplan on the NAS itself. I mapped the drives and am backing up via the Crashplan client on my main computer. Good? Bad? It seems to do the job well. Certainly doesn't seem slow, though I'm not really sure what constitutes slow in this case. Also bought a new router in hopes that I'll be able to run multiple iTunes instances and source everything from the NAS. Doesn't work too bad right now, especially when my roommate's gone. But the Black Friday deal on the ASUS N56U was too good to pass up and the reviews are pretty tops. abelwingnut fucked around with this message at 05:20 on Dec 4, 2013 |

This is how they used to come, more or less. I got a couple sets from them back in ~2009-11 and roughly half would have to go back. I was thinking the individual box was a bit better, but it seems like it's still a crapshoot. Maybe a different SKU or something? Edit: Responded to the wrong post, sort of.

FISHMANPET posted:Does anybody run Crashplan on their Synology? I bought my father a Synology for work and he likes Crashplan so I set it up for him. It's not click and install, you have to manually go through a few steps to get it going and then you need to edit the config file of a client to work with it because there is no configuration interface for the server package. I'd really recommend just doing the folder mount trick to get around Crashplans inability to work with network shares, it takes like 2 seconds. I've done several test restores and it doesn't seem to affect functionality at all. If you do decide to go with the Crashplan server package on the Synology itself then this is the guide I followed.

I was thinking the individual box was a bit better, but it seems like it's still a crapshoot. Maybe a different SKU or something? I was too busy playing sleeping dogs (Thanks steam sales!) last night to get them all plugged in and test them all, but I'm absolutely not going to start shuffling data around until I do. Going to end up pretty pissed if I end up getting a few dying right after I get everything sorted and my array expanded, because rebuilds take fucking forever. These are going in to a my home supermicro box, right now it's got 3 * 3tb drives and 5 * 2tb drives in two separate raid-5 sets, and I'm moving to a single raid-6 set of 8 * 3tb drives. I don't actually gain much space in that exchange, but I do gain some irrelevant performance and peace of mind. The 2s are all WD greens (I know, fucking LOL, I am a bad for getting them back in 2010 for a raid box, they were cheap and I ran wdidle on them) that I want gone as soon as possible. Four out of the five of them are RMA replacements, so I'm basically assuming the last one is a ticking time bomb at this point.

Yeah, Amazon Prime it definitely is not; it's no faster than the EggSaver I always use since I only live one state over. I'd actually be pissed if I'd paid for it, but it's a free "benefit" of my Amex now.

I'm going to be building a new zpool tonight and I was wondering what is the best way to transfer from freenas to freenas was. Should I use the ZFS replication or use rsync?

The 213J arrived today, nifty little machine. I put two spare WD20EARS into it and checked the S.M.A.R.T. status. One drive ran in a Sun Ultra 24, one in a Drobo S. (the drives are rated for 300.000 load cycles) ![]() ![]() So I guess its true, friends dont let friends buy Drobos. I wasnt planning to replace mine because it works "well enough" for my purposes, but now Ill have to look for an alternative before it starts killing my 4TB WD Reds that I just put in there.

You can import your Zpool in the other Freenas if they are the same version. If you want to upgrade your capacity you can replace the drives one at a time and resilver the pool in between replacements. This way your pool stays online.

Bigger drives, more drives, and going from raidz1 to raidz2. As far as I know, you still can't expand a vdev with more drives, right?

Maybe you can add the new vdev to the new pool consisting of the new drives. But you will always be stuck with original vdev, you can't remove a vdev from a pool. I would send and receive the data or, if possible, create a new pool in the same physical machine and copy the stuff from one pool to the other.

That said, what OS did you run on the Sun Ultra? If it was anything Solaris-based, I'm sure as hell that it doesn't support setting AAM and APM on WD drives, and the ZFS ARC isn't really helpful in regards to keeping drives busy to undercut the 8 second IntelliPark timeout (ARC loading your RAM full with the fancy, and buffering writes up to 30 seconds). Unless the box created only minimal reads and almost no writes, then it probably ran almost entirely off the ARC.

I've been getting btrfs errors on my ReadyNAS that lock my data volume to read-only, I ran btrfs-zero-log and btrfsck, still happens. After looking around it sounds like this could be caused by a hardware issue, most likely bad RAM, thoughts? If it turns out to be an issue with the ReadyNAS itself, since I'm out of warranty anyway and I've voided it a couple times over by popping more RAM in, if I pick up something like an N54L, is there a way to move my stuff over without having to buy a full stack of hard drives? Something like an auto-expanding volume? The drives are all fairly new red 3TBs and I don't see any smart errors, so I doubt there's a drive issue.

Combat Pretzel posted:Here's a better idea, don't buy WD Greens. When I bought those drives a few years ago there was nothing comparable on the market. The Sun box ran whatever version of Solaris existed back then. I just wanted to experiment with ZFS. Now that I think about it, it is possible that I ran the WDIDLE3.exe on the drives in the Ultra but not on the drives in the Drobo.

The Solaris one has 600000+ load cycles, the Drobo only 4000+. I don't get it?
