4. Technical Description
I am sponsoring the following fast-track on behalf of Robert Milkowski.
This case introduces a new dumpadm(1m) option for disabling a dump
device.
This case addresses the RFE:
6910925 want to be able to release ZFS volume used as dump device [...]
Currently there is no supported way to disable a dump device
once it is configured on a system. An additional option to the
dumpadm command is proposed as suggested in the RFE:
dumpadm -d none
This will not only unconfigure a current dump device from
a system but it will also make it persistent by putting it
in the /etc/dumpadm.conf file. This changes the current behaviour
where a default dump device was set to 'swap' so if there was
a swap device available which could be used as a dump device
it was configured in during a system boot. Please note that
a ZFS volume which is configured as a swap device cannot be
used as a dump device at the same time so the old behaviour
couldn't configure a dump device in most Open Solaris installation
anyway unless a dedicated zvol or slice is provided.
It is assumed that if a system administrator specifies that
a dump device should be unconfigured it should be persistent
until a new dump device is configured explicitly.
