When I try to import a zpool from a FreeBSD 13.0, to Devuan-Linux kernel 4.19 I receive :
root@yyy:~# zpool import -f ZUSB
This pool uses the following feature(s) not supported by this system:
com.delphix:spacemap_v2 (Space maps representing large segments are more efficient.)
org.zfsonlinux : project_quota (space/object accounting based on project ID.)
com.delphix:log_spacemap (Log metaslab changes on a single spacemap and flush them periodically.)
All unsupported features are only required for writing to the pool.
The pool can be imported using '-o readonly=on'.
cannot import 'ZUSB': unsupported version or feature
Import in void-linux kernel 5.11 works fine.
