Hello All,
I moved the "#!/bin/sh" to point to "bash" however I still see issues
in used the "git://www.linux-cr.org/pub/git/tests-cr" scripts.
Probably I am missing something with my wrong understanding, I am a
little confused with the usage of user space application "checkpoint"
and "restart" and the applications in the "test-cr" folder.
I wrote a sample shell script "my-test.sh" and tried the following
without much success.
#!/bin/sh
#
#
#***********************************************************************************
echo "Incrementing variable ..."
COUNT=$1
X=0
while [ $X -le $COUNT ];
do
X=$(( $X + 1 ))
echo "Value of X =" $X
sleep 1
done
$ cd ~/user-cr
$ mount -tcgroup -o freezer cgroup /cgroup
$ mkdir -p /cgroup/1
$ nsexec -z5000 my-test.sh 100 &
$ echo 5000 > /cgroup/1/tasks
$ echo FROZEN > /cgroup/1/freezer.state
$ checkpoint 5000 > ckpt.image
This generated a "ckpt.image" file of size 2594550 bytes
$ ckptinfo -epv ckpt.image
info: [@8] object 1 HDR_HEADER len 72
info: [@80] object 4 HDR_BUFFER len 73
info: [@153] object 4 HDR_BUFFER len 73
info: [@226] object 4 HDR_BUFFER len 73
...
unexpected end of file (read 0 of 8)
$ kill -9 5000
$ echo THAWED > /cgroup/1/freezer.state
$ ./restart < ckpt.image
This one shows error "Bad file discriptor", what I am missing ?
Warm Regards,
Raghu
