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

# This file is edited by fstab-sync - see 'man fstab-sync' for details
LABEL=/1 / ext3 defaults 1 1
none /dev/pts devpts gid=5,mode=620 0 0
none /dev/shm tmpfs defaults 0 0
LABEL=/home1 /home ext3 defaults,usrquota 1 2
LABEL=/opt /opt ext3 defaults 1 2
none /proc proc defaults 0 0
none /sys sysfs defaults 0 0
LABEL=/tmp1 /tmp ext3 defaults 1 2
LABEL=/usr1 /usr ext3 defaults 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?

Have you booted one of the LiveCD style distributions on this machine? I have heard that one of them may remove the label from swap partitions.


You might try changing the fstab entry:
LABEL=SWAP-hda7 swap swap defaults 0 0
to:
/dev/hda7 swap swap defaults 0 0

and see if that works. If it does, you might want to relabel the partition (when it's not being used), using (I think - the -L option is undocumented):

# mkswap -L SWAP-hda7 /dev/hda7
