Sorry again, it is excellently working
In boot I had noticed
enabling swap DEVICE
swap signature is missing on DEVICE
than understood I had not marked it as swap
$ cat /proc/swaps; sudo swapon --all --verbose ; sudo swapon -s ; free -h
Filename Type Size Used Priority
/dev/mapper/guix-swap partition 1048572 0 -2
Filename Type Size Used Priority
/dev/mapper/guix-swap partition 1048572 0 -2
total used free shared buff/cache
available
Mem: 31Gi 1.6Gi 28Gi 1.0Mi 1.6Gi
29Gi
Swap: 1.0Gi 0B 1.0Gi
Thanks very much for great help and GNU, Guix, and all the stuff.
Thanks again
Shyam
