Sorry the content of original mail I replied to was missed. For clarity here it is: >On 30.07.2012 11:04, Eugene M. Zheganin wrote: >> >> I am aware about how this thing works and what it does.

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?
