Yep, just bent them a little so the fan sits inside, on some rare occasions I can get a small vibration, but since it's very seldom didn't try to improve it yet.

Sorry, wasn't clear, I meant one 200mm side fan on each tower, they also have one 120mm exhaust on the rear, one 80mm for the extra bottom storage and currently one is with 4 x 5in3s with 92mm fans and the other has 4 x 4in3s with 120mm fans, all non hot swap , yeah I'd like hot swap but they are very expensive to source in Europe and I already spend more money than I should on my servers.

Yep:

hmm, still not getting any hits with "mfi" " darco" or "darco/mfi-controller "

I'm trying to install the mfi docker but can't find it on the appstore, docker hub search is enable, it's this one: https://hub.docker.com/r/darco/mfi-controller/ Or this one apparently more recent, but can I install a docker fro github? https://github.com/darconeous/docker-mfi-controller

It's fixed, I used a 3 in 2's I had unused for each case, they are fixed to the PSU holes using old PSU parts, and have a single 80mm fan, I usually only put two drives max in there, partially because the cooling isn't very good, partially because I like even numbers more, next time I open one of the cases I'll take some pictures Left it alone, don't have fans there. I have a 200mm input fan on each, mostly for cooling the HBA and/or expanders. A little double sided tape and the cables (power/reset/leds only) go in through the top fan opening.

? I have two of those, with a small adaptation where the bottom power supply should go for 3 additional drives, so they can take 23 drives max.

Besides possible performance issues, USB is much worse at error handling, you should get an HBA.

I believe pwm is right, you need to specify the partition (p1)

Agree, this would be a good addition and make preclear pretty much dispensable.

Change use cache to "yes" for the shares you want to go to the cache device before being moved to the array.

While I can't speak for LT I'm pretty sure v6.3.5 won't be patched.

Yes. Dell/IBM need to be crossflashed, it's not difficult but it can be harder than a normal flash, still since that one is already pre-flashed it will be plug'n play.

Yes, there are a lot of fakes on the internet, unfortunately a missing logo is not a way to tell, most fakes have the LSI logo, LSI makes OEM versions without the logo, I do usually recommend buying used server pulls instead of new ones from China, I prefer an used genuine over a new fake any day.

Yes, it might need to be flashed to IT mode, but it's easy, like a bios update. It should work with most, can't say it will work with all

For that board I recommend you install the IPMI plugin for fan control

That's a SAS expander, still need an HBA to connect to it.

They should mount in the cache slot, one at a time.

There's no specific limit, depends mostly on the disk size and number of files, the more small files the worse.

Yes for reiserfs disks, though performance can degrade even before that, not important for xfs or btrfs, but you'll want to leave always a few GB free.

Likely the 3.3v issue, e.g., second post down from yours: https://forums.lime-technology.com/topic/62304-issues-reading-some-disks-on-flashed-lsi/

Another possibility is that some drives harvested from external enclosures can be slightly smaller.

No it shouldn't, but I also believe the script is not working correctly with latest unRAID, if you want to do that best to do it manually, see here: https://forums.lime-technology.com/topic/61614-shrink-array-question/?tab=comments#comment-606335
