I've got folders in shares that keep disappearing and reappearing a few seconds later. After such an event, I can't access the folder for some 20 seconds without being thrown back to the containing share. QNAP support hadn't the slightest clue what it might be, and I still haven't been able to sign up for their damned support boards so I can't ask it there. Does anyone know what could be the problem?

Yeah it's a strange path, the file exists though. I threw it in there because NAS4Free already puts another passwd file right there. I've tried it as my normal user and as root, doesn't run either way.

Did you try experimenting with escaping the special characters a bit more. I sometimes have problems when going from direct shell to a script, in that it needs extra backslashes.
Check if this is documented in your web interface manual, also.

This is driving me nuts. I built a new NAS based on freebsd 9.0 and ZFS, and copied data from my old NAS using solaris and ZFS. The copies succeeded, but I found a few errors. On my one partition, everything was fine, according to the command:
code:
rsync -rvnc --delete /old/ /new/
sending incremental file list

sent 628307 bytes  received 1534 bytes  470.56 bytes/sec
total size is 26349714159  speedup is 41835.50 (DRY RUN)
It claims that nothing needs to be done to match the two folder structures. However, on the old machine (solaris), I get:
code:
[me@oldnas /tank/doc]$ du -sk
26242405        .
and on the new nas (freebsd), I get:
code:
[me@newnas /tank/doc]$ du -Ask
25736913	.
[me@newnas /tank/doc]$ du -sk
23929093	.
It seems like something is missing Any other techniques/tools I can use to make sure the copy was good? it seems like rsync should have done the job but I can't shake the suspicion that some files are missing based on the partition sizes.

Rsync should be what is needed... So theoretically the differences in sizes should only be metadata. Because

Maybe you should run "du -s --apparent-size" on both machines and compare those.

They're pretty similar, and if you start with FreeNAS, it's pretty easy to switch over to NAS4Free if you want to try out both (you can then drop back to FreeNAS as long as you don't upgrade the ZFS version on your array). The biggest differences between the two are that FreeNAS has started implementing a modular plug-in system, which makes getting certain 3rd party applications running pretty easy. NAS4Free really hasn't done so, though most of the popular 3rd party apps are already baked in (iTunes/DAAP, BitTorrent, etc), and pkg_add works for most of the others. NAS4Free also sees much more regular updates, and sports ZFS v28, while FreeNAS is back on v15 or so (though v28 is in one of the betas right now, so it's coming). Both share like 90% of their features, though, since they originate from the same project (they split after FreeNAS 7, I believe).

Honestly, for 9 out of 10 people, it'll come down to which WebGUI you like better.

I installed both last month for a work server and decided on FreeNAS because the GUI made more sense and there were a few more options that weren't configurable via the NAS4Free interface.

I did this, with a few modifications (both NAS's are currently accessible from a pretty nice linux box so I just did the md5sums there with the linux-provided gnu tools). Both came up with the same set of files, with the same md5sums so all is well I guess.

I feel like someone really needs to write up or link to a rsync FAQ in the OP.

By default rsync only stats files and compares their modification time and size. This speeds things up tremendously but if you ever doubt file metadata then run rsync with the --checksum (-c) flag and it will use checksums to check if files really are the same or not. It goes without saying that if the dataset is large this might take some time.

There are a few reasons that du might be different from one to another (e.g. sparse file handling) and it's not a huge deal if they're different.

What does the -A flag do for du by the way? I don't see it in the GNU du manpage.

Yeah, the issue was the folder manifest AND checksums were identical, while the 'amount of stuff' was not and I was somewhat nervous. There is a lot of obfuscation using ZFS between how much data goes on the disk and how much data there actually is, between options like compression and dedup and stuff like metadata. I just wanted to make sure I had a clean copy before turning the old machine off and settling in.

I think it's the equivalent to --apparent-size that tonberrytoby recommended, that info is from the freebsd man page.

I'm a fucking pain machine and if you even touch my fucking car I WILL FUCKING DESTROY YOU.


Does this idea make sense from a usage perspective, as well as a "class of product" ie prosumer or whatever, in comparison to my data:

I am a designer and I am starting to pile on data to be backed up on active projects I have going.

I recently had a WD drive die and realized I've never looked at redundant backup in any sense of the word. I'm cheap as hell but I am okay with spending bigger dollars on stuff that requires it.

I recently bought a lovely chinese media player (Mele A2000) for my projector and haven't figured out exactly how to set it up as I can plug 2.5" SATA drives into the top of it directly, for a bit I thought I'd make it serve up my movies/music for the projector and I wouldn't need anything else. It does work for that fairly well.

Now combining my interest in
-media storage for playback
-work backup, direct or wireless
-redundant backup
-frivolous gadgetry

I am thinking of a drobo/synology but leaning towards synology due to price

I like the small 2.5" form factor one (DS411 slim) or just the ugly clunker for maximum space (DS413j)

I would be fine building a unit but looking at the stuff synology offers with their drives and not having to do anything I would be happy to spend the money on that

Is it overkill for what I'm doing?

If your data is worth more to you than the cost of the hardware, then no it is not overkill. Synology makes excellent products.

I just picked up a DS413j, I'm very impressed with it so far. The software is worth a great deal of the price as far as I'm concerned.

The mobile apps work great, I can send stuff and download things from anywhere. I still haven't played around with most of the stuff it can do. My only issues with it so far are that the automatic port opening is a bit finicky, but manually assigning ports fixes that, and adding a drive to the array is slow as balls. Took two days to add a third 2TB drive. But unless you have an incredibly pressing need for more space right now that's not a big deal.

I'd keep in mind too, that you can get nearly twice the space for about the same price with the 3.5" drives. 2TB WD Red drives were nearly the same price as 1TB 2.5 drives during the last sale I saw.

I just did this, and CrashPlan seems to be working fine thus far. I was able to seamlessly adopt my existing 400GB backup set, using these instructions. I have one of the Intel models, upgraded to 4GB RAM - from what I understand, CrashPlan may silently quit on you if you're RAM limited (e.g. on the ARM/PowerPC models).

I have an M1015 right now (ordered a 2nd with that auction) and when I got it in, I went digging through my box of old pci cards for brackets. I found that a lot of them have screw holes in the same places, so if you have a stash of old stuff sitting around you may be able to find something that works for free.

Barring that, I would just use it without one but ebay tends to have several for sale for ~10 each at any given point if you are really concerned.

One thing that really annoys me with all the custom built storage server solutions is that it's really hard to find a chassis and a controller that enables you to have HDD error LEDs for each drive bay.

Ages ago i had a promise supertrak raid card and promise hotswap bays, and it would indicate the faulted drive with a red LED. Everything else about it sucked, but knowing exactly which drive to swap out with a new one was very nice.

Any suggestions for which card and chassis to get if i want this? It sounds like it gets even trickier when you pass drives through to ZFS instead of using hardware raid.

The norco 24 bay chassis is supposed to at least have a LED header on the backplanes, so i suppose you could do something neat with an arduino and some zpool status scripting.

Thats an awesome unit.

Just finished setting up a DS413j for personal use moving down from a custom unraid nas (e2180/2gb/8TB pooled). Wish I could spend a bit extra and bought an Intel based unit for expansion as well as the ARM processor even at 1.6Ghz bogs down quick on PAR repairs.

Super impressed that effortlessly out of the box DSM takes care of dyndns, port forwarding, autoban of ip's, backup vpn, ups monitoring, custom scheduled smart testing, and sms/email alarming. All of this took days of hunting down custom modules, fixing shell scripts, and never as seamless on unraid.

Realtek chips will work, but you will find the experience is less than perfect, due to less than perfect Linux/BSD drivers. You're likely to get sub-standard transfer speeds, dropped connections, and general "why the gently caress is that happening?" issues. Intel Pro NICs, on the other hand, benefit from having very solid drivers, and thus perform noticeably better.

Thanks for the heads up. I did some searching on this and You are correct. End of the day I may have to get a new MB and sell that one. Or I can use the eSata and get an expansion box.


Edit: More I think about it, If it presents an issue, I'll just get a NIC card, and use the eSata port to another drive enclosure if needed.

That's a neat-looking rig! Does it do RAID6? I've taken to always recommending people use raid (whether in software or hardware) that has two parity disks, because the increasing size of disks and their steady URE rate (it's been argued by Adam Leventhal, a zfs developer, that even RAID 6 will become unusable in 2019).

I wish zfs would add one feature that it's missing, namely adding parity disks to already-existing pools (it's a feature that's listed on some wish-list, and it's supposedly coming - eventually).

Other than NIC-issue already mentioned, you can always get an IBM M1015 card if you're lacking ports. Also see the above about large disks and URE.

I haven't had the best of luck with Realtek NICs even on Windows to be honest. There's something to be said for buying a decent brand of NIC when it comes to getting everything to work as you'd think they should. It's pretty easy to cut corners on something like a NIC and Intel doesn't do it as much others in large part due to so much of their NICs being used by businesses.

This may be more of a general FreeBSD question, but I have a problem with FreeNAS deleting files from my /etc directory on boot.

I have created an rsync task to do a push to a remote server once a night. The remote server requires a user and password to connect, and FreeNAS says I have to create a file with the password in it. I put the password in a file at /etc/rsync_module_backup_password and gave it chmod 600 permissions, owned by root.

Whenever I reboot the FreeNAS system, the /etc/rsync_module_backup_password file is gone.

Why is this? Is there a better place to put the password file?
