I create a dm-zap mapper upon my zns device (emulated by qemu) and then format ext4 file system on /dev/dm-0.
But when I try to write somthing into that file system, it reports a lot of errors. It seems that they are Zone Invaild Write from the nvme cq of write commands.
Then I find the information in readme shows than dm-zap can only transfer sequential zones into conventional zones. So I try blkzone report /dev/dm-0 to check the zone type, but they are all sequential zones.
So how can I create a usable file system upon dm-zap? Thanks.
