Hmm...well, wtf... How is it rebooting but looking exactly as I left it when I log in? My unRAID server at home just got unplugged on accident and it was completely dead until I went back in and restarted it. Had to go back in and restart the array and all that.

No, not all testing is with a parity check underway. My parity needs correcting? I haven't had an unclean shutdown. Not that I know of. The thing is in a datacenter...it should never be shutting down. Ever.

Good to hear something isn't right. Because, if this WAS normal, I don't know if I'd be able to continue to use unRAID. It's SO slow. Diagnostics attached. Thanks so much for the assistance. tower-diagnostics-20191206-2141.zip

"Brutally slow" as in, if I'm seeing 4.5-5 megs, I'm stoked. This is transferring a file from an unRAID share to the desktop of a VM. Transferring from my laptop to a share is lucky to break a meg.

Ah, ok. Doesn't sound like slapping SSDs in would help much. That sucks. Oh well. Thanks!

And, by "brutally slow", I mean EVERYTHING is drive-speed limited. The CPUs never even really do anything. Drive speed is by FAR the bottleneck no matter what I try to do on the thing. I noticed this when I was trying to render a video in my "Adobe render machine VM" and it was taking FOR. EV. ER. (Cue Sandlot clip.) I'd really like to use my server to render videos as that's what I actually got the thing for. lol I don't use it for that though because my weak ass hyper-threaded dual core i7 powered laptop will crank out a video in LITERALLY a tenth of the time...

My array is...BRUTALLY...slow and I've been trying to think of a way to speed things up beyond adding a cache drive, which I already have. I was thinking slapping a fast(ish) SATA SSD in with all my slow spinners wouldn't do anything but...I dunno...Will it? I was watching this: ...and it made me wonder...maybe unRAID CAN utilize faster storage in the array to speed things along. So...what's the official verdict? Toss a few Samsung SSDs in with the spinners or no?

Got ya. I'll give it a shot this weekend. Thanks!

I have an NVMe SSD in the server that was intended to be the cache drive but I'm having trouble getting the BIOS to recognize it as it's installed via PCIe. The extra SSD I have is SATA. Would I be able to assign it to the VM somehow?

Yes, the vdisk and the source files are on the array. I'd like to dedicate an SSD to the VM so the VM can run off of it and I could put the source files on there for rendering. I'm hoping that would make the thing render as fast as it should. Maybe I could just install the SSD and put the source files on it...maybe that would help. How would I "attach" that disk to the VM?

I have a W10 VM that I use (try to use, anyway...) to render videos in Adobe. It's just on the array and the disk speeds are SO...INCREDIBLY...SLOW...that it takes an unbelievably long time to render. I stopped a render yesterday after over 2 hours because it was BARELY making progress...my flaccid dual core laptop did the entire render in that same amount of time. At the rate the server was going, it would seriously have taken 10 hours?...maybe 12? I don't even know. It's INCREDIBLY slow and, when I look at resource manager, I notice the disk access is pegged. Disk speeds seem to be the culprit. So...I have a spare Samsung 860 Evo laying around. This got me thinking, how could I install it and dedicate it to the VM? What I'm wondering is, is it possible to assign that disk ONLY to that VM? Maybe using "unassigned devices"? Also, would it be possible to move the VM onto the SSD after I install it or will I have to create a new VM? No big deal if I have to reroll a new VM. Thank you!!

Cool cool. Thanks!

Yea, I am running vdisks on all the VMs. Do they just use the cache disk automatically or do I have to change some setting?

Ah. Got ya. Makes sense. I'm not doing anything super intensive on most of my VMs, but there is one VM that I could use the performance. Maybe clean the cache off and just assign it to that VM?

I don't know specifically what's on the cache drive and that doesn't really matter to me. The issue I'm having, and the reason I'm needing it to clear off, is it's filling up and making my VMs do strange things. So, I suppose files related to VMs are what I don't want on the cache drive.

Very interesting. I would think telling shares to not use the cache drive would keep data off of the cache drive. I guess not. I'll read up. I set the shares that had data on the cache drive to "yes" and the mover says it's running now. So, I'll give it some time and see what happens. Thank you!

My 256GB cache drive only has 11GB of space free and keeps filling up. I hit the "Move Now" button and nothing happens. I also tried everything mentioned here and still nothing. Anyone have any ideas as to how to get the files moved out of the cache and onto the array? Logs attached. tower-diagnostics-20191004-0746.zip

Awesome. Glad it was a help.

Honestly, I don't remember. Sorry.

Almost forgot...things I'm looking at: Duplicati and AntiDupl...TOTALLY unfamiliar with both of these, though. So...thoughts?

...accomplish these two goals? Can be a single tool...a Docker...a couple separate tools...whatever. Doesn't matter. 1 - Deduplicate files on an array. I have a TON of data on two separate servers and I need a way to compare the data between the two and trash duplicates leaving one dataset. 2 - Mirror the two datasets so the one server (the one in the datacenter) can act as an offsite backup for the other server (the one in my house). I know CrashPlan used to do this but no longer does. (lame) End goal being to have one, deduped, mirrored data set between the two servers. Anyone know an efficient way to accomplish this?

The replacement(s) is actually made of metal. Now that it's in a datacenter, I'm not worried about it, anyway. I freeze my balls off in there. It will too.

Yup. I replaced it and all is well yet again. I even bought an extra thumb drive to leave on top of the server in the expectation that I'm going to have to do this again. lol

...exactly what I was afraid of. 😛

It looks like the Mover is running now. Thanks! So...where would one go to read about how to decypher unRAID logs? Would really like to learn how to so I don't have to keep coming here and bugging you guys every time something breaks. (And I'd like to be able to help here, as well.) It just looks like gibberish, though.
