Anyone with any trip reports on cloud based storage to backup a Synology NAS? Right now I see options for Amazon's S3 storage and some company called HiDrive based in the UK. Anyone using these or something else to cloud their Synology? I know it has rsync built in so maybe something that route would be better with a network drive to dropbox. Looking for options if my house burned down or a tsunami. edit: Seems the network folder to a dropbox account is a no go, since "Cloud Station" doesn't sync files bigger than 1GB. edit2: Wonder how much it would cost to setup a goon only cloud storage? kill your idols fucked around with this message at 20:51 on Jun 21, 2012 |

I just set up a DS412+ using Crashplan backup using this guide. It has been backing up fine for a week and seems to have been working fine for other people for a while now. It is however so ridiculously cheap to back up multiple terabytes that I am kind of terrified Crashplan will murder my dog or something. Also I have zero experience using it with one of the cheaper ARM-based devices. I imagine that would probably be way less smooth.

I've been using tarsnap for awhile now, it has been great. A bit more expensive than vanilla S3 but it is pretty drat slick.

Just had ten Seagate ST3750640NS (750gb) drives arrive on my doorstep. These are not going into my personal server, but instead for the mass NAS software reviews I intend to do.

Also, thideras - nice, I like that idea a lot. I went with Nexentastor community for my current build but I wonder if I shouldn't have just gone with FreeNAS instead. Thankfully with ESXi, it should be pretty easy to change if I want to.

I pass the controller with the drives on it to the VM, but I run software RAID within the VM. However, my (admittedly relatively limited) knowledge of ZFS says that I should be able to import the pool into a different ZFS-capable OS.

I joined SA just to get in on the SpiderOak referral thread. If you are looking for a space to put around 10 GB, both SpiderOak and SugarSync have easily reachable referral bonus to get you there, and cheap enough to make it bigger. GoogleDrive has 6 GB to start but no referral program. Same with Amazon Storage. Both offer better vakue paid plans than the first two. If you are looking for that size space, here are referral codes to get us both bonus storage if you use them to sign up for the first two. None of the above seem to have file size limits. Sugar Sync: https://www.sugarsync.com/referral?rf=cx740wic3q7d4&utm_source=website&utm_medium=web&utm_campaign=referral&shareEvent=692020 SpiderOak: https://spideroak.com/download/referral/1a4d958bf039fc3743ddec82c7acacbf Also in the SpiderOak thread there is a code to get 5gb free.

Oh holy gently caress. My IcyDock enclosure started beeping a few days ago, which either meant a temperature problem or a fan problem. Seeing as how if I touched the fan to stop it and let it start again and the beeping would go away for a while, I figured it was a fan problem, and I was planing on digging in tonight and ordering a new one or something. To rule out temperature I decided to install smarttools (not installed by default on Solaris) and check the temps. They all looked good. I also mess around with setting up smartd and getting it to see all the drives and then what it takes to get the system to email my gmail address rather than the local mail spool. All the while I'm watching something on my TV that's streaming from the server. The drat thing is still beeping, so I go into the room where the server is, and since I've got the monitor it's hooked up to turned on, I see that a drive has failed. I go back to my ssh session and discover that five drives, out of 10 in use (with 1 spare) have failed, all in the same enclosure, all in the same raidz vdev. So it was reslivering and got up to 500k file errors when I powered off the system thinking it was the enclosure. Now that I've swapped the enclosures the drives live in, still 4 failed disks, though god bless ZFS, it's still trying to resliver as much data as it can onto my single spare. E: It looks like only 4 drives are actually bad, before the last reboot 3 drives were degraded and 2 drives were removed, and now after the reboot I've got 3 degraded, one online, and one unavailable. gently caress.

Dur, I posted this in the Enterprise Storage thread... I have 8x 1.5TB drives in a JBOD enclosure with dual sas ports and a LSI RAID card to go with it. I'm considering using a not so old machine I have laying around with a dual core proc and 8 gigs of ram and a smallish SSD and doing ZFS for file sharing at home. I currently have an n40L for Home Server 2011 but would like to offload the storage of music and video on an actual file server / NAS. I've seen a lot of talk of ZFS and just wonder what the preferred implementation is. FreeNAS, Nexenta, Open Solaris? I've rolled my own NAS in the past with Linux and NFS / iSCSI but want to try something different. Ideally I can get it running and just forget about it. I'd like notifications on drive failure or SMART alerts. What do you recommend?

Holy poo poo I managed to come back with no data loss. Only one drive actually died, and the rest were "degraded" because they had errors when the enclosure poo poo itself, but the reboot brought them back, so all is well, just have to RMA that one drive.

DarkLotus posted:Dur, I posted this in the Enterprise Storage thread... Barring user-mode and unsupported stuff, there are really only two common ZFS implementations, Solaris (as used by NexentaStor) and FreeBSD (as used by FreeNAS). Really all you can do is test both and pick a product you like but I went with FreeNAS because FreeBSD's hardware compatibility is better than Solaris. My setup is an N40L w/16GB RAM, Intel NIC, 5x3TB drives in a RAID-Z with FreeNAS 8.2 beta which handles NFS, SMB and BitTorrent duties. It took all of 10 minutes to set up & add some scheduled SMART tests and by default it'll email you daily logs and perform scheduled ZFS scrubs. FreeNAS is a little behind the times with its ZFS version, but both implementations are stable and several years old at this point and I can see little use for features like deduplication when storing predominantly music/video on a RAM and CPU-contrained home server. On the plus side, you'll have no problems importing a ZFS pool created with FreeNAS into NexentaStor if you decide to switch. Still it's probably best to try both out with some non-critical data. FreeNAS is in a little bit of a transition stage right now, having lost a big chunk functionality between v7 and v8. 8.2 is in beta and incorporates plugins for non-standard functionality (which run in a BSD jail and require you to create mountpoints to access data outside of them) and then 8.3 will bring the FreeBSD base (and ZFS version) up.

How does ZFS handle using an SSD for cache? Is there anything special I need to do with the configuration to ensure redundancy?

Read about zil and cache (write and read caching, respectively) on the ZFS Best Practices Guide if you really do have a special setup/need and consider what's in the ZFS Evil Tuning Guide before doing anything else because zfs is a well-tested system and if there were better values than the default, they should be the default. Other than straightening out bottlenecks, there's not a whole lot you can do performance-wise (but why would you need to? Even on consumer hardware (my low-power N36L, to be exact), I've seen SMB get maxed out on LAGG'ed dual-gigabit NIC). BlankSystemDaemon fucked around with this message at 09:52 on Jun 25, 2012 |

ZFS supremacy  I just powered off my machine after nearly 300 days for a move; I hope all 20 HDDs survived the move  I'm taking this chance to dust/clean the machine and the HDD trays since they're pretty dust-caked at the moment.I think in this new apartment, I'm going to put it + the UPS in the nice and large laundry room. Need to get a table to set them on though; do the larger Ikea Lack tables support a decent amount of weight? I bought a little one for $7.99 to hold my LaserJet and it seems fairly solid.

Pelican doesn't make cases the size of small coffins given the material's rigidity would be compromised at certain size / volumes, but there's special manufacturers for transporting stand up basses that cost nearly as much as my own bass at $7k+ (most professional double bass players, especially in classical, have basses costing at least $15k though so it's still steep for them anyway). That's just way above and beyond what someone trying to transport a few rack servers would be looking for, crazy as it may sound. Most shipments of rack servers I've seen are freight in big, nondescript wood boxes to hide the boxes with Cisco, EMC, and HP logos.movax posted:(and a Pelican case of the size and weight capacity I'd need is like $400) movax posted:Solaris 11 running on a X58 board with a i7-920 and 24GB of RAM (no ECC, I know

necrobobsledder posted:My dad managed to pick up a rack for his audio equipment that's admittedly too shallow for a Norco case at 29"+ depth, and it was maybe $300 from Musician's Friend / Guitar Center. It's just a big wood cabinet with felt and casters bolted and glued on. If all you have for rack mount equipment is just the Norco and you don't move often it's far cheaper to build a rack every time than to even bother with a mobile rack. 8U and 12U racks off ebay are massively expensive compared to even a Lack coffee table + reinforcements and most require assembly anyway given they're flat-packed like Ikea stuff. I will be moving within the year, most likely. I actually have a pretty bad-rear end 24U Dell rack that I got off Craigslist for $100, and when I still lived at home (where the rack now resides in the basement), I easily mounted the Norco + UPS + friends in there. Maybe when I get a more permanent place... quote:Turns out if you're using an Intel board on newer chipsets with ECC RAM you're basically going to need RDIMMs to go beyond 4x4GB of RAM due to the skyrocketing cost of 8GB UDIMMs + reduced reliability and downclocking as part of Intel specs. In that territory, you're solidly better off for cost-effectiveness by just using a consumer-grade AMD machine that all support ECC RAM (both registered and non-registered) and taking a hit on power efficiency. No way I can make up for a $400 premium at $.06 / kWh in my utilities running a powerhouse server unless it's running near peak a lot. Sadly, it makes even more sense if you're running a high-capacity server farm for most enterprise (HPC != enterprise btw) workloads. That's good to know, thanks. I probably should have ECC memory, but I've been OK for the time being, and everything that is actually important is backed up in multiple places.

How do I convince Hitachi to do Advance RMA in Australia? The Asia helpdesk (based in Signapore) claims it isn't offered in Asia - US maybe, but not Asia. I'd rather not have to resilver an entire 3TB drive off a 4 drive raid-Z array. I'd prefer to image the broken drive over so at least 99% of the checksums are right there. Less to recalcualte and less chance of loss, that way.

So I've got two RAIDZ vdevs, and a whole pile of bad disks in one of them. According to SeaTools 2 out of my 5 drives are bad, but ZFS has only faulted one of them, so as of now my data is safe (the computer is turned off right now). I can get a hold of two disks to use temporarily until I get the RMA back, but I'd like to try and resliver them before I send off the disks. I don't have enough physical ports for two extra disks, unless I completely remove one of the vdevs. So, if I boot into single user mode or something (Solaris Express) will ZFS resliver the first vdev even though the second vdev would be missing completely? Obviously there would be no file access, but assuming the reslivering works fine, I could then reboot with the second vdev back in place and everything would be fine, right?
