Hi list,
today I upgraded one of our servers from 10.0 to 10.1 with
freebsd-update. GENERIC kernel, ZFS 2-way mirror, GPT, nothing
special. After booting kernel, when trying to mount the
root file system I get: 'cannot mount, error 5' or something.
Strangely I got this error a few weeks ago at home, running
CURRENT with custom kernel:
https://lists.freebsd.org/pipermail/freebsd-current/2014-October/052900.html
I created the pools and datasets manually via console. Has
anything changed? With legacy mountpoint, or that one needs a
boot dataset, or something?
Thanks,
Michael
