hunraid Posted January 6, 2019 Share Posted January 6, 2019 Hi All, I upgraded from 6.1.x to 6.5.3 and then the Cache drive became unusable due to the file type, I selected "Yes I want to do this" and formatted it, assuming it could rebuild a cache. After formatting once, it stated it was still unmountable. I'm now in a loop where I select "Yes I want to do this" to format the disk, select format, it goes through the motions and returns me to the main screen where it's still unmountable. I posted on Reddit, and was told by a very helpful person this is a known bug, and I could either downgrade, then copy off the cache stuff, but I'd already formatted, so as a consequence I went with the second recommendation and installed the Unassigned Devices plugin from the github link in the forum post here. Set it to destructive mode, expecting additional options, but it appears to be the same process. When I go into detail on the drive it says it's in ext4, but then also says it has no file system, which I find a little puzzling. I'm running a HP ProLiant MicroServer G7 N54L microserver and the disks in question can be found in the screen cap I have along with the syslog zip. Hope that's all the required information, many thanks for any assistance. tower-diagnostics-20190106-0510.zip Quote Link to comment
JorgeB Posted January 6, 2019 Share Posted January 6, 2019 With the array stopped click on the cache drive, change the filesystem to the one you want to use and click apply, then start the array and format the cache. Quote Link to comment
hunraid Posted January 6, 2019 Author Share Posted January 6, 2019 Thanks that's worked perfectly - I chose xfs, as it was the only one I'm familiar with that wasn't auto. Will that be ok? Quote Link to comment

hunraid Posted January 6, 2019 Author Share Posted January 6, 2019 Perhaps I was unclear, I assumed that over the course of the next few weeks unRAID would continue to utilise the disk as a cache drive once more. Obviously if the disk is formatted everything is gone. Quote Link to comment
