Don Lapre posted:Yea, that would work fine then. If a synology just use their hybridraid. For all the praise ZFS gets in this thread, SHR seems quite nice, at least at first glance. Does it have some non-obvious Achilles heel that I'm not seeing for why it doesn't get more praise in this thread?

DrDork posted:Price and performance of the Synology lineup is a big factor. Synology devices are a lot more expensive, especially for anything above 2 drives, while being slower than DIY solution: a DS413 is about $500 with a 1.06GHz CPU. A N54L on the other hand, runs $380 and packs a 2.2GHz CPU. Ninja Rope posted:Also if your Synology dies you need to buy another to read the data.

Ninja Rope posted:Oh, maybe I'm wrong but I think SHR is their own thing whereas the RAID0-6 are standard md. I'd be happy for someone to correct me, but my understanding is, given the following example  is this is actually under the hood four Raid5 arrays (or three Raid5/one Raid1?), and it would be possible to get mdadm to parse it as such. SHR with 2-disk redundancy is the same but Raid6. To be clear, I'm more asking if this is the case than telling you this is the case.

So I'm reading the N40L supports port multipliers if you flash the hacked BIOS. Has anyone added an external enclosure using the eSATA port? I'm curious how much of a negative impact might be had with those disks having to share the pipe, but it seems a great way to expand the number of disks a MicroServer has access to.

Tivac posted:Synology NAS boxes seem like they'd be nice but the custom filesystem & price are turning me away. Also since it's basically a customized linux distribution they publish their source code modifications and people have been able to compile drivers for extra hardware and get it working on third party devices such as the MicroServer. Similar concept as the Hackintosh.

Don Lapre posted:Greens are fine if you already have them and disable head parking. Just dont buy them in the future. I agree. Just use wdidle3 and then you are fine doing SHR, which is software Raid5. I'd suggest doing a pretty deep health check on all of them first though. I also don't understand why you think you would lose 10GB of crap instead of 1TB of crap when a 1TB drive dies if you aren't using any sort of redundency.

You are thinking about spanning. Someone correct me if I'm wrong, but no striping takes place in spanning so the data on the other disks would be fine or at least easily recoverable.

eightysixed posted:Then why does literally everything say one disk failure results in complete data loss over the entire array? Again, please someone correct me if I'm wrong, but when you are spanning your file size is generally limited to the size that will fit on the largest disk. You wouldn't be able to store a 5tb file in the case you mean. Likewise the small files would also be on one particular disk. Striping is Raid 0. You aren't striping when you are only spanning.

Think of it this way, hypothetically - I have three 2TB drives in JBOD, containing a large 5tb file. If one drive fails, my file is gone for good. This should work in the very same sense with a lot of smaller files, because they will be spanned over the entire array, not contained to there one physical volume, no?
|
My only practical experience with spanning was with Windows Home Server, and from what I'm reading the rules that were true with how it did it may not be true for other ways spanning can be done.

Ninja Rope posted:If all the drives appear as a single giant disk to the OS, then the loss of one drive is going to lose all data on that drive. Whether or not you can recover the rest of the data is up to the filesystem and restore tools you use. You might lose it all. If they show up as independent drives then you only lose what's on one drive. In the case of XPenology, the OS is seeing all the disks independently and using mdadm linear to concatenate.

AlternateAccount posted:Hmm, shouldn't I have more space on the array available than this? Yes you should. It looks like you haven't expanded the array after adding one of the 1TB disks. Basically, in this situation SHR should under the hood be a mdadm Raid 5 that is three partitions of 232.89, and a second that is two that are 698.62. So I would expect capacity of roughly 1164.4. So not counting the lost space to the OS, basically the capacity of the largest disk gets taken away in parity, but the lower are available. https://www.synology.com/en-us/support/RAID_calculator Don Lapre posted:No. The primary benefit to shr is it allows expansion. He can use the extra space by setting up a second volume though. This is not at all correct. Sub Rosa fucked around with this message at 03:10 on Feb 16, 2014 |

Except when you add the replacement drive it would say repair instead of expand.

Megaman posted:Synology is proprietary which means the following. Since the Synology formatted disks only work with Synology devices and ONLY the same exact synology model you purchased and ONLY with the configuration from that particular device (granted you backed it up before the time of crash), if something happens with the synology you're completely hosed unless all your ducks are in a row (you have the exact device/config/disks standing by). It's actually just mdadm under the hood, and the raid can be put back together under plenty of other linux systems. Pretty sure also isn't correct that you can't just move your disks to a new different model Synology and it will also find and recognize the volume.

Anyone have any experience backing their NAS up to Amazon Cloud? I'm not re-subbing to Backblaze, so I need to get another backup solution sorted. I've even found some people who have their ACD mounted to a VPS they are using as a Plex server as well as running Sonarr/etc/etc. So far it all seems to be a level of "figure it out yourself" beyond my ability and the closest things I can find to guides are old. So I would be happy at the moment just getting everything backed up, but Amazon's own program is slow and buggy, as is apparently the Cloud Sync program on the synology.

CopperHound posted:I'm having a hard time deciding if I want to build my own raid/home server or just buy a Synology (and nuc if it turns out that it doesn't have enough horsepower). I like the idea of SHR, but that can just manually be recreated with LVM, right? I think I would enjoy tinkering with the initial setup, but I know I don't want to stress about trying to remember the proper CLI commands when swapping out a failed drive. Rolling your own XPenology box is also an option. Speaking of.... I've been running XPenology for years on an HP N54L, and I'm about to wipe it, install 6 newly shucked HGST 8TB drives, and most likely going with a XPenology 6.2. I had been at 5.0 for a long time, and one of the new features is btrfs. I remember this thread being the ZFS fan thread, and I've seen btrfs compared to it, how does it hold up? Can you do any sort of scrub with btrfs? Open to arguments that I should really consider something else, but I don't know why I would pay for unraid, and FreeNAS I remember scrapping 10 in a way that made me think it was a project I'd not entrust my data to.

Yeah my cpu is a 2.2Ghz AMD dual core that can't be trusted to transcode 720p. I'm not finding enough (any) people who have accomplished this in my exact situation, so I might just buy a Shield if I find a good black friday deal instead of trying to find a cheap low profile GPU that will both work in XPenology and Docker Plex.

Well obviously anything important I'd be able to replace because I don't confuse having a NAS with having a backup. I do have parts I could reuse like a 2500k but I would need to pickup a mATX mobo, and for the cost of that from what I've seen I should probably just go new parts. Still very confused from the recent posts in this thread if a Ryzen 3600 actually works with ECC with the mentioned ASRock Rack mobo, but maybe either way it's added unnecessary cost.
