file system question
Hi Everyone,

Not really too much of a problem but I thought I'd ask:

I've just installed Fedora 14 on a dual boot. I went with the suggested installation (first time I have done this), but I was wondering, do I have swap space? When I type "cfdisk" I get:


      Name                    Flags                Part Type            FS Type                        [Label]                      Size (MB)
      sda1                                          Primary            vfat                            [RECOVERY]                    5099.68           
      sda2                                          Primary            ntfs                                                          26213.97
                                                                          Unusable                                                          1.04            *
      sda3                    Boot                  Primary            ext4                                                            524.29            *
      sda5                    NC                    Logical            LVM2_member                                                  28172.10            *

I cannot see any swap tagged partitions here, but when I type "swapon -s" I get:

Filename                                Type                Size        Used        Priority
/dev/dm-1                              partition        4128764        0        -1

So it says there is 4GB of swap space right?
Is this part of LVM2_member? I must admit I know very little about LVMs.
Also, where is sda4? Again is this within the LVM or something?

Thanks in advance!

look in /etc/fstab and run lvdisplay as root

That makes a lot more sense now,

You can have up to 4 Primary Partitions (sda1, sda2, sda3 and sda4). If the 4th partition is a Primary Partition, then you cannot have any more partitions.


You may designate a Primary Partition to an Extented Partition. You may think of this as a promotion. In your case sda4 is an Extented Partition and therefore unuseable. Consequently may have Logical Partitions (sda5, sda6, ... up to about sda64). You have an LVM partition in sda5.
