Linux error after swapon -a: cannot find the device

Question

Please give me advice on how to solve the error below.

Linux details:

Kernel version: 2.6.18

Linux-OS-5.3

Thanks

 # fdisk -l | grep /c0d0p6 /dev/cciss/c0d0p6 31790 33845 8385898+ 82 Linux swap / Solaris # mkswap /dev/cciss/c0d0p6 Setting up swapspace version 1, size = 8587153 kB # echo '/dev/cciss/c0d0p6 none swap sw 0 0' >> /etc/fstab # swapon -a swapon: cannot find the device for LABEL=SW-cciss/c0d0p6 

Answer 1

Try

mkswap -L SW-cciss/c0d0p6 /dev/cciss/c0d0p6 

Edit: could you try changing the fstab entry you describe above to read

/dev/cciss/c0d0p6 swap swap defaults 0 0 

Answer 2

sudo swapon -a

I got this;

 swapon: cannot find the device for UUID=03599533-3a7e-453c-99d2-dd9470e336fe 

then I tried

sudo swapon /dev/sda12

that being the address of my swap partition on my device although not absolute. It worked like a charm. I hope that works for you too.

Answer 3

Use the command

$ blkid 

It will show you the list of all partition and their respective UUID

Copy the UUID of the swap partition

Use the command

$ sudo nano /etc/fstab 

Enter your root password. Then, in that file replace the existing UUID with the copied UUID from blkid

hit ctrl+o , hit enter, then hit ctrl+x

restart your computer
