Swap area problem

Question

hello
I don't have swaparea partition, and I want to use pm-hibernate , so I used this commands
# fallocate -l 512M /swapfile
# dd if=/dev/zero of=/swapfile bs=1M count=512
# chmod 600 /swapfile
# mkswap /swapfile
# swapon /swapfile
then I edited /etc/fstab
/swapfile none swap defaults 0 0
after that I edited /etc/default/grub (GRUB_CMDLINE_LINUX)
GRUB_CMDLINE_LINUX="resume=/dev/sda6 resume_offset=1232896 "
/dev/sda6 contains swapfile and I found resume_offset after using file
[root@arch ~]# filefrag -v /swapfile
Filesystem type is: ef53
File size of /swapfile is 536870912 (131072 blocks, blocksize 4096)
ext logical physical expected length flags
   0       0  1232896           32768
   1   32768  1265664           32768
   2   65536  1298432           32768
   3   98304  1331200           32768 eof
/swapfile: 1 extent found
in the end I used "grub-mkconfig > /boot/grub/grub.cfg "
after all this  pm-hibernate can't work it shows me this message
"PM : swap header not found"
what should I do ??

it says that log  was not found. and I don't think that this is a problem
but you have reason suspend is not montionned at all in this file, I'm sure that I suspended to ram (I can make differance ^^) , perhaps pm-suspend can't writes its log !!
I have a different opinion:
1. It is a double-problem that "log" was not found, Why would the script be in that "else" bracket? To log that the unloading of module $1 failed.
2. It is a log about hibernate because it says so all over the place. Compare your two pastebins to see the difference. Besides again it is old: October 2 was last Friday. You probably got the wrong log again - log problem or not.
Try this to look at the last 200 lines of it
tail -n 200 /var/log/pm-suspend.log |more
Troubleshooting the reason behind suspend/resume-problems can be pretty tiresome.
I think you should take more time to gather the information. Also you suddenly changed thread topic, which is fine, but you did so without providing information about how you configured everything around pm-utils - compare it to how you provided the relevant information for your initial question regarding swapfile.
