There have been several threads about using zfs on armv7 over the years. Some of them are from 2013 and indicate little sucess. Others, from 2015, indicate it works... https://lists.freebsd.org/pipermail/freebsd-arm/2015-March/010607.html https://lists.freebsd.org/pipermail/freebsd-arm/2015-March/010649.html There have also been some bug reports as recently as 2017 indicating that people are still doing this on small armv7 systems. -- IanReceived on Fri Oct 04 2019 - 17:37:26 UTC
