https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=229958 --- Comment #5 from Andriy Gapon <avg@FreeBSD.org> --- I'd say that there is a worm can of problems related to ZVOL support in FreeBSD. One issue is that we use spa_namespace_lock as zfsdev_state_lock. Another is that we call functions like zvol_rename_minors() from a sync-ing context. The locking logic in ZVOL code is really non-obvious because of all the interactions, including GEOM. Once upon a time, I tried solve one part of the problems with this change https://reviews.freebsd.org/D7179 But I am not sure if that's the right solution. -- You are receiving this mail because: You are the assignee for the bug.
