Sorry mate, haven't checked in a while, but cheers for your thoughts! I'll investigate and see how it goes 🙂

Hi all! I have about 30Tb of USB3 HDD's spread across a half dozen devices. Currently as a test, ive plugged them all into a hub and hooked it up to unraid happily (Showing as unassigned devices currently). I'm looking for guidance as to the easiest way to do a cold storage backup of some of the critical shares on my system (And have the drives available to other OS's when not plugged into my unraid) Anyone got some ideas on the best way to deal with a bunch of JBOD's like this? I envision it will be plugged into the server once a month or so to do some sort of incremental update, but im open to suggestions on best practices. Cheers everyone!

@JorgeB thanks mate, didn't look hard enough.

Hi brains trust! Scenario: Have an 64tb array consisting of 8x8tb hdds. 1x parity, 7 array disks. Lately one of the drives in the array has been failing, and I've been constantly removing it and rebuilding it whilst I swap other variables around eg cables raid cards etc On to the fun bit. I've bit the bullet, and ordered a 14tb drive to replace it, but, owing to the fact that my 14tb drive needs to be the parity, I'm hoping there's a way to shortcut the rebuild time. My idea at the moment is to rebuild my failing drive one last time, and then add the 14tb in as a second parity. Once that's done, remove 8tb parity and drop it in the array. Two full parity checks to complete the operation. Any thoughts on a better way? Had a look on the forums but didn't see my particular scenario.

Yeah I'm having the same issue - I've gone so far as to add the community scrapers as well, and cant get anything to run a successful query unfortunately,

+1 - This was my bugbear also

fair enough. I guess its all about "expectation management". I always thought that the cache drive was able to function as a mirror or sorts, with the mover doing some sort of "parity check" on a schedule. In an ideal world, that's all i want my NVME drive to do, just act as fast storage for frequently used files. With so many edge cases, a developer cant keep everyone happy all the time, and i definitely respect that!. Many thanks for your time!

Bugger. Many thanks, at least now i know, and can start at least thinking about it differently.

Brains trust, this has been something Ive wanted to achieve since I discovered the cache disk many moons ago, and I'm not sure if I'm not setting it up correctly, or if its something Unraid doesn't currently support. Amongst other things, I have a 40TB Media Share, with a 2TB NVME drive set up as a cache drive on my system. What i want, is when a file is put on the array, or a file is read from the array, it is then copied over to the cache disk, thereby not needing to spin up the array next time it get accessed, and it is a mirror of the file on the array, ensuing backup. When the cache disk gets full, i want it to overwrite the older files from that share off the cache disk. I've had a pretty deep dive into the cache options, and squid's CA Mover Tuning plugin with no avail. The premise of this is that with my media files, it seems that there is only ever a very small portion that gets used on a regular basis, eg a TV Show thats being binged, the new movies being downloaded etc. When i tell my cache drive to "prefer cache" for my media share, it just hoovers up the first portion of the share, which is completely useless. Brains trust, I bow to you wisdom! is there any way to achieve this? Or is this a feature request? Cheers!

Had the same problem here with the same motherboard. This post saved me tearing my hair out, wish i had of found it 3 hours ago haha.
