Hi,

I just found that my fc3 system's swap partition is "gone".  When I
installed the system, I set it to 1Gb.  The kernel is 2.6.10-1.766_FC3.  I
don't know when it started, but here are some information:

# free
             total       used       free     shared    buffers     cached
Mem:       1035748     658792     376956          0     145380     272540
-/+ buffers/cache:     240872     794876
Swap:            0          0          0

# cat /etc/fstab

LABEL=/1                /                       ext3    defaults        1 1

      1 2

LABEL=/var1             /var                    ext3    defaults,usrquota 
      1 2
LABEL=SWAP-hda7         swap                    swap    defaults        0 0
...

I tried this:

# swapon -a
swapon: cannot find the device for LABEL=SWAP-hda7

The system log does not show anything related to this problem.  Can
somebody tell me what may cause this problem?  how to check it further and
fix it?

Thanks a lot!
