configuring a dump device

Hi All,


i tried to create a new logical volume "lvoldump" on a newly created vg01 that belongs to newly created physical volume (not on the same physical volume for vg00).

Now i am tryin to separate swap and dump areas so, i configured /dev/vg01/lvoldump to be a separate dump device and add an entry to /etc/fstab however, i do not need that /dev/vg00/lvol2 remains as a dump area so i issued:

# crashconf -d /dev/vg00/lvol2          (to discontinue the use of the currently configured lvol2 as dump)

and after verification with #crashconf     it seems that it succeeds to disable lvol2 fraom being a dump area. However, after reboots /dev/vg00/lvol2 still figures within #crashconf output.

Is there a way to permanently disabling /dev/vg00/lvol2 from being a dump area?


Thanks in advance

Re: configuring a dump device

You may also need to use 'lvlnboot' to configure a dump device.


Also check /etc/rc.config.d and see if there is a 'crashconf' configuration file there that gets looked at when the system boots.
