Hi all Now mkfs on raid10 which is combined with ssd/nvme disks takes a long time. This patch set tries to resolve this problem.
Are those fixes also possibly related to the issues I found earlier this year about it's very weird discard handling whenever the originating request wasn't essentially chunk-aligend ?
What I found back then is e.g. discard of 4x32gb raid10 taking good 11 minutes via blkdiscard w/o explicit step option.
I still have blktraces of that available, the relevant thread part with further more detailed followups can be found at:
