I see the same metadata spread as with the old filesystem in btrfs fi df, totl at 23 and used at 2.38 GiB. What I find strange is that this filesystem has Data, System and Metadata in "single" profile, is this the new default for a 200 GiB file system?Single is default for data. Metadata (and system) will normally default to dup on a single device, raid1 on multi-device, EXCEPT on detected SSDs, where it defaults to single as well, because the firmware on some ssds will dedup it in any case. If you know your ssd isn't one of the deduping ones (as I do, here), you can of course overrule that by specifying modes at mkfs.btrfs time.
It was both times the same Samsung 840 EVO. Has this SSD detection been added recently, or did older versions of mkfs.btrfs not detect an SSD through a crypto layer, maybe?
