PC-BSD has the following additions to their /etc/devd.conf file:
# Sample ZFS problem reports handling.
notify 10 {
match "system" "ZFS";
match "type" "zpool";
action "logger -p kern.err 'ZFS: failed to load zpool $pool'";
};
notify 10 {
match "system" "ZFS";
match "type" "vdev";
action "logger -p kern.err 'ZFS: vdev failure, zpool=$pool type=$type'";
};
notify 10 {
match "system" "ZFS";
match "type" "data";
action "logger -p kern.warn 'ZFS: zpool I/O failure,
zpool=$pool error=$zio_err'";
};
notify 10 {
match "system" "ZFS";
match "type" "io";
action "logger -p kern.warn 'ZFS: vdev I/O failure,
zpool=$pool path=$vdev_path offset=$zio_offset size=$zio_size
error=$zio_err'";
};
notify 10 {
match "system" "ZFS";
match "type" "checksum";
action "logger -p kern.warn 'ZFS: checksum mismatch,
zpool=$pool path=$vdev_path offset=$zio_offset size=$zio_size'";
};
So it's very (relatively) easy to configure devd to do this.
We just need some scripts to plug into the action lines above. :)
