My reply again then:
Unfortunately I am a less experienced user so no clue how to disable
GEOM_RAID but i am hit by this issue. My zfs setup is totally messed up.
Would appreciate if you could share the trick.
Additionally: building a new kernel solves the issue naturally but is there
anything more convenient solution? What is your trick?
Thanks in advance,
(and sorry for messing up the mail thread)
