drugdoctor Posted January 30, 2019 Share Posted January 30, 2019 I recently added a cache pool to my Server, then upgrade my cache 2 drive to match my cache 1 drive. WD black nvme 500GB cache 1 /AData nvme 500GB cache 2 to two WD black nvme 500GB cache 1 /500GB cache 2. Now the cache 2 drives shows no reads or writes being made. Can someone please advise? Thanks in advance, sceenshot below. Quote Link to comment
JorgeB Posted January 30, 2019 Share Posted January 30, 2019 Cache2 is almost certainly not being used, please post the diagnostics: Tools -> Diagnostics Quote Link to comment

JorgeB Posted January 30, 2019 Share Posted January 30, 2019 18 minutes ago, drugdoctor said: Does this mean anything? Yes, but unrelated, NVMe devices don't spin down. Cache pool is kind of a mess, cache2 is not part of the pool like suspected, but the remaining member has multiple data profiles including DUP, which is very strange, unless you did a manual balance specifying that, though you could balance and re-add the second device these type of issues can sometimes lead to unpredictable behavior, I suggest you backup you cache to the array, you can use this to help, clear both devices with: blkdiscard /dev/nvmeXn1 Then re-format cache the pool and restore the data. 1 Quote Link to comment
drugdoctor Posted January 30, 2019 Author Share Posted January 30, 2019 Looks like it worked (writes after balance). Thanks for the help! Quote Link to comment
