2 logical volumes

[maalamaal]

hi All,
i am using dell inspiron 640m laptop and i have dual boot now one is XP and other is fedora 9
in the boot menu i have 3 options one is xp and 2 fedora versions which i think is ok as i read some where that it stores last 3 versions in the boot menu

problem is when i select one of the fedora while booting i see a message saying 2 logical volumes present - i think i made some mistake while re installing my fedora
can some one explain why its happening and how do i get rid of it?
also if i have to post the message that i see how do i do it( is that message stored anywhere elese)?

I think it might be an added swap LogVol.
try 'dmesg | grep LogVol'
or try 'lvdisplay'.

[maalamaal]

this is what i get when i do dmesg | grep LogVol

[vemu@localhost ~]$ dmesg | grep LogVol
Kernel command line: ro root=/dev/VolGroup00/LogVol00 rhgb quiet

"how can i merge these 2logical volumes and make it only one logical volume?"

LogVol01 is the VMS swap file system (used for paging, swapping, virtual addresses, sleepmode and now cgroup (a small kerenel recovery area.) Your system needs it.

read the installation guide - section about partitioning, types, and the default vs custiom .

but it never used to say that i have 2 log vols before?
so u mean to say that my conf is alrite?

[SlowJet]

The default install has been the same since FC3 or before.
/boot 83 ext3
lvm 8e with / lv ext3 and swap lv

The swap f/s does not show in all commands.
