Fail to use ZFS ZVOL as a gmirror component

[Алексей Волков]

Hi there!

In a most recent FreeBSD 9.1-RELEASE i found a serious issue with zvol
and geom layer. For instance it is impossible to uses zvol as a gmirror
component.

I have posted a bug report
http://www.freebsd.org/cgi/query-pr.cgi?pr=175323 and look forward to
get fixes.

Does any one face the same issue and have any suggestions or workarounds?
