I have installed FreeBSD onto a raw image file using QEMU Emulator successfully. I have formatted the image file using the ZFS file system (ZFS POOL).
Using the following commands below I have successfully mounted the image file ready to be opened by zpool
sudo losetup /dev/loop0 [path-to-file].img sudo kpartx -l /dev/loop0 sudo kpartx -av /dev/loop0
However with the next command show below....
sudo zpool import -R [MOUNT-PATH] -d /dev/mapper
I get the following error message
The pool can only be accessed in read-only mode on this system. It cannot be accessed in read-write mode because it uses the following feature(s) not supported on this system: com.delphix:spacemap_v2 (Space maps representing large segments are more efficient.) The pool cannot be imported in read-write mode. Import the pool with "-o readonly=on", access the pool on a system that supports the required feature(s), or recreate the pool from backup.
I cannot find anywhere online about the feature called 'spacemap_v2'. How do I install this or how do I mount my zfs pool to be writable. I know I can mount it as read-only but that defeats the purpose of what I want to do as I want to be able to write data to copy/paste data in its mountable platform interface.
Does anyone know how to achieve this. I shall be grateful for a response.
