Can someone convince me to move from WHS to freebsd7 + zfs? (or perhaps a linux distro with lvm or whatever its called). I have a fairly powerful pc which I use mostly for sharing videos to about 5 PCs. 2x 500gb 1x 300gb, I'd like to be able to expand as I need it (i think i'm using about 800gig so far). I'm hating the idea of limiting a folder to only one hard drive.

How do you guys with raid5 handle upgrading storage :S From what I can see you either have to spend lots now to buy more than you need, or pay more later when you upgrade because you didn't buy enough. Doesn't that throw anyone off?

Can anyone provide a link with some info on resizing raid-z arrays? I vaguely remember reading somewhere that you can upgrade drives, you just can't add them. Possibly related question, how does raidz work with different sized drives? vanjalolz fucked around with this message at 11:37 on Jul 17, 2008 |

Thats frustrating :/ I guess if you want real hardware redundancy you need to buy your disks up front. All well and great until you have people like with me with a 300, 500 and a 700 (and one dead 500)... How good/reliable is the freebsd zfs implementation? I'm much happier working in BSD (solaris is weird, i'm trying it in a vm) but I'd put in the effort to learn it if it meant less problems down the road. quote:# What can I do if ZFS panics on every boot? But this is my backup!  And thats zfs on sun! :S Might be old though... vanjalolz fucked around with this message at 14:32 on Jul 17, 2008 |

It sure can't be the user interface, since it's the same in Linux and BSD, since it's Gnome. quote:Right now, if you're serious about longterm ZFS usage, Solaris is the way to go, until at least that Pawel guy removes the experimental status of the port. The solaris installer had an option for installing on zfs or ufs, i picked zfs to try it. Later it asked me to add some disks which it would mirror, so I have 2x 8gig disks mirrored and that part runs ok. I understand that raidz booting is tricky, and I'm not too interested in booting my system from a raidz. I intend to run my system from its own drive. Memory requirements are a bit worrying, but I'm on 2gb of memory now which seems like a nice amount considering how light my usage will be. I think I've got my self in a corner with upgradability. My drives are all retarded sizes(p300, s500, s750) and I don't have that many ports (2 sata, 2 pata, 2 sata on pci card).

I wish there was a way to add a parity drive to an existing 3 drive array in zfs. Would make migration so much easier

vanjalolz posted:I wish there was a way to add a parity drive to an existing 3 drive array in zfs. Would make migration so much easier Extending on this question, what happens if I make a 4 drive raidz array and then take down the parity drive, can I still use the array? Can I write to it? If I readd the drive, will it catch up automatically? If so, what happens if I add a clean drive, can it catch up?

Interesting, so following that logic I should be able to start a 3 drive array with 0 parity drives, and add one when I'm ready, right? Also, I remember reading ages ago that SATA is plug and play. I still hear his quite often, but just how plug and play is it? Can I yank the power/data cables on a sata drive while my computer is on or will things break? (assuming the O/S is writing nothing to the drive ofcourse)

Yeah I have a feeling thats the case, still worth asking. How many (750gig) drives would work efficiently on the old PCI bus? I've got 2 sata ports at the moment, not sure if adding another 2 ports would be worth it.

Fifty-Nine posted:I used these for my new NAS box: Sup nexenta buddy  I installed nexenta this weekend on a 4x750 array raidz1 and its pretty nice. I'm cut that i can only get ~12mb transfer speeds over gigabit ethernet because this motherboard has 2 drives on a pci sata card + gigabit ethernet with no pcie. Must move to atom when I get the chance, this is crazy.As for moving /var, I imagine you'd use the zfs mount command (check man). How can I test the individual drive speeds on my nexenta system? I thought dd if=/dev/dsk/c3t0d0 of=/dev/null count=3GB was clever but it doesn't work.

I wanted to try something similar in ZFS but couldn't figure it out. I dont see why high-risk software doesn't exist to migrate a raid1 to raid5 or striped to raidz.

For enterprise users it might be considered useless because they buy their hard drives in bulk. Oh, and high risk in the sense that running this operation and then losing power would be a problem. While Raid-0, Raid-1 and Raid-5 all have different uses, there is definitely a lack of an upgrade path when going from a no/lower-number raid to a higher raid level. For home users there is a purpose for this kind of technology. A quick google shows plenty of people asking how this can be done. I've even included a link to a (very technical) explanation of how it can be done in ZFS to show that even the SUN devs are seeing this as a legitimate use case. http://blogs.sun.com/ahl/entry/expand_o_matic_raid_z vanjalolz fucked around with this message at 07:31 on Sep 19, 2008 |

Any enclosure will do as long as its the right type for your hard drive (sata/ide etc). In australia you can expect to pay like $30 for one, not sure where you are. If you don't want the enclosure you can easily add the hard drives to your new computer and everything should run fine.

Jonny 290 posted:I use rsync scripts on a launchd schedule. It beats cron, because if you are in sleep and it comes time to run a launchd job, when your machine wakes or boots it'll run those jobs (read: sync) automatically. It's pretty snazzy, though I'm so paranoid I run hourly rsync backups and do a daily Time Machine backup to an old 160gb at night. Do you mind posting your rsync scripts/settings so I can see how you do it?

Its so easy to get carried away chasing speed and getting cockblocked by the PCI bus when making a NAS. I think everyone should take a deep breath and really consider the chances of breaking 100mb/s throughput in real world use.

Has anyone here used OpenSolaris and Nexenta? I'd imagine OpenSolaris is harder to use (given a linux background) but it would be balanced out with better package support - it doesn't sound like OpenSolaris has any more packages than Nexenta though :S Nexenta v1 had me patching rtorrent manually every update, but v2 has rtorrent in its software repo and it built with out a hitch

I've got a nexenta solaris file server set up with some shares and for the most part its working well, but I made my shares before I saw the stuff about making the case sensitivity = mixed and now when ever i transfer files into the share over sharesmb they come out with 000 permissions. How can I change the default permissions of smb create files? I know it has to do with ACLs, but I can't work it out.

NOTinuyasha posted:I had similar bad issues on OS X, spent an enormous amount of time on the trac trying to sort them out. I needed to install a copy of GCC over the Apple one, applied two patches just to get a compile, another two for stability. I'm proud to say I got at least one change made in my name but unhappy I wasted that much time. uTorrent with Windows is still way better. I can't even imagine trying to get rtorrent to run on an NAS, it killed my dual G5 Xserve as it was. Maybe give Transmission a shot? Beyond that I've heard alright things about Enhanced Ctorrent for limited NASes but that's completely banned on quite a few trackers. Wow sounds like rear end, I thought fink sorted most of that stuff out? Transmission is a pretty good suggestion, I'll give that a shot. (After I get my server to boot, upgrading libc required a reboot and it never came back up...)

Does anyone have any tips for trouble shooting a Nexenta/Solaris system? Everything has been running great for the last couple of years, but yesterday everything started going stupid slow. I think that the system is slow because disk read is slow - starting a new process (such as an ssh session or 'top' etc) is slow as hell. When I managed to run top, I didn't see any weird processes burning through CPU. I ran zpool status and it said my storage pool was fine, my syspool had one corrupt file (because I had to hard reboot the first time I ran into the issue). The corrupt file was an mrtg config which I never use. It all started yesterday while I was streaming a video file. Everything was running great, I paused the file for 10 minutes and it wouldn't resume. I quickly found out that samba and ssh weren't responding so I rebooted but it didn't help. tl;dr: Nexenta 2.0 system became slow overnight for no reason. I think its I/O related. How can I confirm/diagnose?

What are my options for keeping two zfs file servers in sync, other than rsync over the network? Ideally I'm looking for something like rsync that would let me push changesets onto an external hard drive which I would carry to the other file server and get it to sync. I know zfs has zfs send which does something, I'm just not sure if I can use it for my purpose. I guess using the zfs tools would be for block level sync which wouldn't work for two-way. Maybe some sort of script which copies recently modified files to the external drive would work. Has anyone tried something like this before? vanjalolz fucked around with this message at 02:58 on Feb 10, 2011 |
