  • Print the debug messages:

echo '::zfs_dbgmsg' | mdb -k

  • Clear the debug messages, will be realy cleared on next insert (DilOS extension):

echo '::zfs_dbgmsg -Z' | mdb -kw

  • Change the capacity of debug messages (default == 4MiB, example for 1KiB)

echo 'zfs_dbgmsg_maxsize/W 1000' | mdb -kw

  • Disable the debug messages

echo 'zfs_dbgmsg_enable/W 0' | mdb -kw
