I read that mkfs.btrfs will work on a device that is not formatted.
I am on z/linus SLES12 and I tried to execute mkfs.btrfs on a 3390 mod-9 device.
This did not work. It will default with the --mixed option.
It will work if I format and partition the device.
Code:
linux140:~ # mkfs.btrfs /dev/dasdb
SMALL VOLUME: forcing mixed metadata/data groups
'/dev/dasdb' is too small to make a usable filesystem
Minimum size for each btrfs device is 16777216.
Should this work? Are there other required options?
The Suse 12 system is installed on a 3390 mod-9 device.
