How to create secondary swap

Giuseppe_13 — Thu, 18 Feb 2010 10:50:30 GMT

I have a too small swap area on VolGroup00/LogVol01 and I can't extend the logical volume because there aren't free disk space.

I have free disk space in VolGroup04 and I have created a new LV for secondary swap:
VolGroup04/LogVolswap

How can I to configure the LogVolswap how secondary swap ?

Thanks

Hi.

You can leave it at the default, or if you know your old swap area is faster set it to lower for the new area (or vice versa).

default priority is ok.

The new swap has priority -2
The primary (already present) has priority -1
