Rubicant Posted July 27, 2020 Share Posted July 27, 2020 I've been having nothing but problems since I swapped out my cache drives with a pair of Intel NVME drives...now my write speeds are insanely slow moving files from drive to drive on the array. Would yall mind taking a look at my diagnostics and seeing if Im missing anyhting..cause it shouldnt take 3 hours to transfer 44GB from one disk to another. Of note, the array is presently regenerating the two parity disks..but that's never affected my write speeds that badly... Am I missing something? Please help. Thanks :) blake-diagnostics-20200726-1951.zip Quote Link to comment

trurl Posted July 27, 2020 Share Posted July 27, 2020 You mention changing cache but you don't say whether cache is involved in the transfer and what is source or destination. Quote Link to comment
Rubicant Posted July 28, 2020 Author Share Posted July 28, 2020 Cache is involved in the transfer I think, but my results were slewed by the ongoing parity rebuild. I’ll check it once the parity rebuilds, and I have a 100% apples to apples comparison of the transfer and file set. Quote Link to comment

If you are transferring between disks on the server, only the source and destination disks are involved (and possibly parity. So if your source or your destination is cache, then of course cache is involved. Otherwise, the only way cache might be involved is if your destination is a cache-yes or cache-prefer user share. And you MUST NOT mix disks and user shares when moving or copying files. Quote Link to comment
