Are there any practical lim= itations to just using a ZFS pool created on Linux? Technically no, but I would boot a FreeBSD live CD first and import / attach= the pool. Generally, ZFS on Linux is typically a few feature flags behind Fre= eBSD, so there shouldn't be any issues with doing this. >=20 > If there=E2=80=99s reasonable doubt of issues I'll just rebuilt the pools u= nder FreeBSD, but would be great if I didn't need to do that. It'd be cool i= f it=E2=80=99s just a # zpool upgrade away hah :) That should do the trick, but bear in mind it will be hard (read: impossible= ) to go the other way once upgraded.=20 Anders=20 >=20 > Cheers, >=20 > --=20 > Cheers, > Ruben Schade in s/Singapore/Sydney/ > https://rubenerd.com/ >=20 > _______________________________________________ > freebsd-questions@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.or= g"
