It should be an ideal workload for SMR disks. Assuming they smartly designed the "plots" which we already know they didn't. Streaming/sequential read only workloads ought to just go right along.

Streaming/sequential read only workloads ought to just go right along. If they were just SMR disks. WD designed them with a CMR portion that is designed to be flushed and written to an SMR area. On the 6TB drives I have my estimate is that the CMR portion is around 300GB. When the CMR portion runs out the performance drops heavily as it is forced to write data to SMR to empty CMR. This poor performance has had larger raid arrays mark drives as defective. The comedy from the tears looks promising.

SMR is fine if you're writing huge chunks of data to an empty disk (not a ZFS rebuild mind you, that's not sequential enough) so they're probably just fine for Chia if you're blasting your dumb loving sudokus onto an SSD then moving them.

15K RPM SAS drives plot fine and last forever. It's the secret that they don't want anyone to know.

They mean the drives are very loud as they're designed for datacenter or sever room usage.

I almost laughed myself out of my chair because of that.  Also, in other news: corrective zfs receive, which makes it possible to heal corrupted data on pools, is only missing one test (which currently panics on FreeBSD) before it's ready for its final review. This will finally mean that all those ZFS standard I/O streams that I've been writing to SMR disks as a way of backup (which is the only acceptable use of SMR), will be possible to restore from, without loading the whole chain of snapshots onto a new pool.

I respect Chris a lot, but sometimes I get the feeling he isn't really following OpenZFS too closely, despite having moved from OmniOS to Linux on the storage cluster he's got running at work - because that code has been in development for almost 3 years.

Has anyone here setup Wireguard on their Synology via Docker? A friend mentioned I should look into that as opposed to opening holes in my router to access SAB/Sonarr, and I'm googling around now to see what's involved.

I have WireGuard running on a raspberry pi and unless you’re fairly comfortable with docker networking I’d recommend just using Synology’s VPN server* instead. WireGuard is nice and lightweight but it’s not like OpenVPN is bad at all. * unless the client is an iPhone. As of last year there didn’t seem to be any way to get the config and certificate files from the synology into the ovpn app on iOS.

I run Wireguard directly on the router, and that has been the best solution I've found by far. Many routers are compatible with custom firmware that makes it possible even if it's not a feature on the original firmware. Not trying to manage my VPN on a device by device basis has felt like a huge upgrade.

In the process of setting up this huge rear end 12 bay QNAP. Trying to sort out some workflow poo poo. If I have a bunch of 3d models I'm slicing from a desktop, does it make sense to just use qsync or some other software to mirror all those files to the PC so that load/render times really quick? I haven't hosed with SSD caching at all, and I'm not sure I can plug in an external or PCIe SSD which would leave me with the full 12 bays for raid 6 Also, I have my old 4 bay QNAP, no way to attach that directly to the rack through a spare ethernet eh? My wiring situation is a bit all over the place, and if it saves me going out to buy another switch that would be great. If I do end up grabbing a switch, any reason to go managed vs unmanaged for a Nas serving a couple desktops? w00tmonger fucked around with this message at 01:10 on May 22, 2021 |

This might be a dumb question that I should ask in another thread but, hey, there are no dumb questions, right? So, I have a Synology DS220j that I’m very happy with. For work, I access a big personal folder on a shared FTP server that can be very slow and laggy. I’d much prefer to do the work locally, but my work macbook’s HD is too small. What’s the best way to mirror a folder, I don’t know, one-drive style, between my local NAS and the work server? Synology has a lot of backup options but I’d like something more live so that I can freely upload and not worry about it.

Synology’s cloud share package works with FTP and will do exactly what you want. I would double check that you’re not breaking some big legal policy based on the type of data you’d be copying over, but otherwise it’s an ideal solution. FTP syncing done on the 220j, folder accessed using SMB or whatever on the work computer(s)

Anyone know if the fan it comes with is the typical enterprise 'we absolutely do not care about acoustics'? Not sure if I should just preemptively buy some noctuas. The 3V pin on SATA connectors are a left-over from a time when SATA was meant to supply power to more than just disks, which a new SATA standard has repurposed because someone think it makes for a good way to power-cycle the drive if the signal is briefly set to high and then back down to low. Unfortunately a lot of ATX power supplies keep the 3V signal high because of the old standard, which forces the drive to be constantly off. If you find a backplane which carries 3V at all, it'll be one that's meant for the newer specification where it's just a brief pulse.

Welp, that sucks. Supermicro has continued the only good 90-bay JBOD chassis that is front-and-back loaded was ever made, and replaced it with a top-loading variant. The whole point of the front-and-back loading design was that you're only ever moving a few disks on individual sleds (a maximum of 2 per sled, if memory serves) if you're going to be servicing any of them, rather than moving 90 disks at a time. Anyone who's ever played around with gyroscopes knows what happens when you apply a force to a spinning object, and it doesn't take an engineering degree to figure that when servicing any one of 90 disks, the number of times the entire server has to be moved out on its rails is enough for gyroscopic precession to risk decreasing service lifetime of the disks in question.

Yeah, but gyroscopic precession only works when you're applying a force perpendicular to the plane of rotation. With the way the disks are loaded in that new chassis, the force of sliding the bay in/out of the rack should be almost entirely parallel with the plane of rotation, so the force simply gets applied directly against the spindle, which should be more than capable of handling it. And the spinning disk should act as a stabilizing factor, anyhow. But, yes, the end result is you're now moving 90 drives instead of 2, and that's not great regardless of orientation. Seems weird to change it since something that dense would be almost certainly only seen in datacenters where you'd generally have good access to both the front and back of every rack. Upside: instead of two tiny-rear end little fans for the 2x PSUs, which seems...questionable...for that setup, you now get 5x big rear end fans for the 4x PSUs, which seems a lot more reasonable, and presumably much better internal thermals as a consequence.

I had a bunch of top-loading Sun X4500s at a previous job like 12 years ago and they're still running, we didn't see any higher failure rate on the drives in those systems versus horizontal loading systems. I'm sure it's fine. Edit: Now I miss the Sun that made cool poo poo.
