Hello, I'm currently testing out encryption (using a recent snapshot of 13-CURRENT) on a backup system that will eventually go offsite once 13 is released. I have created a pool just using default options but zpool output lists the ashift as 0: root@:/etc/ssh # uname -a FreeBSD 13.0-CURRENT FreeBSD 13.0-CURRENT #0 main-c255641-gf2b794e1e90: Thu Jan 7 06:25:26 UTC 2021 root@releng1.nyi.freebsd.org:/usr/obj/usr/src/amd64.amd64/sys/GENERIC amd64 root@:/etc/ssh # zpool get ashift offsite NAME PROPERTY VALUE SOURCE offsite ashift 0 default I'm sure it can't actually be 0. I've seen mentions online that this is a problem, but also that it just means "auto" ashift. Either way it's unnerving. I wanted to check with zdb, but this doesn't seem to run at all as I can find no cache file on the system and passing a pool name just gives "No such file or directory" Is there any way I can run zdb on this system? Regards, Matthome | help
