That way, a GEOM event can cause a change to a ZFS vdev. For example, when you remove a disk, the vdev's status will change to REMOVED. However, vdev_geom will sometimes attach multiple vdevs to the same GEOM consumer. If this happens, then geom events will only be propagated to one of the vdevs. Steps to reproduce: # Create two pools with a shared spare $ sudo zpool create -f foo da0 spare da1 $ sudo zpool create -f bar da2 spare da1 # Physically remove da1 $ zpool status pool: bar state: ONLINE scan: none requested config: NAME STATE READ WRITE CKSUM bar ONLINE 0 0 0 da2 ONLINE 0 0 0 spares 13402883250515786666 REMOVED was /dev/da1 errors: No known data errors pool: foo state: ONLINE scan: none requested config: NAME STATE READ WRITE CKSUM foo ONLINE 0 0 0 da0 ONLINE 0 0 0 spares da1 AVAIL Both spares should be listed as REMOVED. Instead, only one is. --=20 You are receiving this mail because: You are the assignee for the bug.=
