January 4, 20251 yr I have a single cache drive, an old thing I had lying around, and want to upgrade it. I've seen various approaches to do this, most a couple or more years old. What is the current consensus about switching cache drives? Thanks - and a happy New year to everyone!

January 4, 20251 yr Community Expert Do you want to upgrade to a mirror with 2 new devices, or remain as a single device?

January 4, 20251 yr Community Expert Solution For single device upgrade you can use this: https://forums.unraid.net/topic/46802-faq-for-unraid-v6/#findComment-511923

January 10, 20251 yr Author So I sat down to do the upgrade, but I hit a (small?) wall. I'm supposed to set my shares to: Primary: pool Secondary: array Mover: pool-> Array. Ok, that's understandable. However, some of the shares I have (well, I don't care about the others, but this is the case with my main share which hosts the Public, SMB-shared data) have only one storage option, and it's set to Cache- I can't choose a secondary storage. I'm pretty certain my Public share is NOT on the cache drive since the data it holds is about 20 times the SSD cache drive I have, so what gives? Any ideas would be awesome... EDIT I think I may have hit a bug? When I enter the Public share settings, Primary is Cache, in the Secondary Storage pull-down menu every option is greyed out. Now, if I set Primary to Array and then back to Cache, the pull-down menu allows me to choose the array as secondary storage! Is this normal? 7.0.0-rc.2, btw.

Ok, learned something new today - and it makes sense, but it doesn't explain the menu behavior... Let me repeat in other words: the share has Cache set as storage only and choosing a secondary storage is impossible until I change the storage to Array and back to Cache. That's what doesn't feel normal.

January 10, 20251 yr Author 1 minute ago, JorgeB said: Upgrade to stable, it was released yesterday, and retest. Huh, funny, it didn't alert me.. Let me check manually! Yup, there it is. Ok will do.
January 10, 20251 yr Author Ok, 7 stable fixed it - the Public share actually appears to be on the array instead of cache, as it should.
January 10, 20251 yr Author ...and back with another question (sorry ). I moved all the data off the old SSD, put in the new ssd, removed the previous pool, added a new pool with the new disk. However, under Pool devices the SSD appears with FS:vfat and the note Unmountable: wrong or no file system So I go to Array operation, format Unmountable disks, after a couple of seconds the process seems to end (GUI is released again) and under Pool devices the same details (vgat, wrong fs) appear again... Am I missing something? Edit: hmm I suspect there may be partitions on it, from what I've been reading? Not impossible, the drive was used before... Edited January 10, 20251 yr by Krakout
January 10, 20251 yr Community Expert With the array stopped, click on the pool, change it to a different filesystem and re-format.

I guess I'll have to go to the cli to figure out the partition table. EDIT ahhh yes, fdisk gives: /dev/sdb1 40 409639 409600 200M EFI System /dev/sdb2 411648 937701375 937289728 446.9G Microsoft basic data Will try deleting... Edited January 10, 20251 yr by Krakout
January 10, 20251 yr Community Expert Unraid should still try to format with the specified filesystem, you could just wipe it, but post a screenshot first from where you are seeing vfat
January 10, 20251 yr Author Here's the screen. Notice there's no Format button, just a greyed- out "Mount" one... EDIT Oh wait, after a couple of array start-stops, it finally formatted it! Weird... Let me reboot to make sure it's ok. Edited January 10, 20251 yr by Krakout
January 10, 20251 yr Community Expert Glad it's resolved, but I meant format using an Unraid pool, not UD.

Only under the Operations tab there was a format button (such the confirmation checkbox next to it), but it wasn't formatting - what I described in a previous post. Stupid me, didn't occur to look at the logs at the time
