Hi all, This a follow up to a previous thread in freebsd-geom where it was determined that geli is functional in 11.0-CURRENT and it could be an ARM problem. I have been unable to geli attach in RPi, even with a very simple passphrase ("test"). Has anyone had success with this? I have tried on an external usb, da0 as well as a partition on the SD card itself, mmcsd0s3. The geli init appears to work, and a geli dump reveals that a master key was indeed written to the device. What is even more puzzling is that a geli onetime will work for the device, so it would appear that geli is functional, but something has gone wrong with the master key generating/writing/reading operation. Can anyone shed some light on something I am missing? Is geli not fully supported on ARM?
