JorgeB Posted September 5, 2020 Share Posted September 5, 2020 With the array stopped change cache slots to 1, click on cache and set filesystem to auto, start the array and then grab and post new diags. Quote Link to comment
bombz Posted December 20, 2020 Share Posted December 20, 2020 Hello, I am also running into this concern. I had (1x) cache drive. I made a duplicate of it for backup before I proceeded. I put the cache drive back into the server. added slot 2 cache disk for - RAID 1 cache setup When I start the array my main cache disk states: Unmountable: No pool uuid <xfs> It also stated it required to format my main cache disk -- I assume UnRAID stated this as that is the process to make a new RAID 1 cache pool So that was not good. So I stopped the array removed <unassigned the second cache disk> edited the slots back to (1X) cache disk Selected <auto> for the FS started the array and I was back to normal. Moving forward: What I am looking to do if possible is Keep my existing production cache disk Add another cache disk (RAID1 Mirror) Have a redundant cache setup However, based on what I attempted to do, that may not be possible with existing data on the production cache disk I would love some feedback on this. Thanks, Quote Link to comment

Thanks, Hello again, I am going to line up some time to take my server offline again. I would like to set this up as RAID1 mirror so my cache is protected. I realize you would like logs, I plan to get to that. From what I can tell based on what I have tried, I cannot add a second cache disk to the array (on the fly) to create a RAID1 mirror on the cache set (2x cache disk). What is the best method to adding a second cache disk to my array with data already on cache disk #1? Edited January 24, 2021 by bombz Quote Link to comment

It depends how your current cache disk is formatted and the general health of your server. You won't get any useful answers unless you provide your diagnostics. There's just too much guesswork involved. Quote Link to comment
