Hi,
I am using the NFS directory as the root file system, and it works
now. I have worked to make the warning/error messages away during the
node is booting up. Now, I am trying to create and add my own dracut
modules, but I find it doesn't run during the node is booting up.
I created one directory named "48xcat", and there're 5 files in it:
"check install premount prepivot xcatroot"
All of them are simple, the contents of "install" is:
"
#!/bin/sh
echo "installing xcat dracut modules..."
dracut_install mount umount
inst "$moddir/xcatroot" "/sbin/xcatroot"
inst_hook pre-mount 10 "$moddir/premount"
inst_hook pre-pivot 88 "$moddir/prepivot"
"
premount will mount another NFS directory to the mount point in the
file system, like this:
"
#!/bin/sh
echo "in pre-mouting script"
mount 192.168.11.107:/tftpboot /.statelite/ro
"
prepivot only has one line to echo something there.
xcatroot only has several lines:
"
#!/bin/sh
echo "xcatroot is running..."
#inject new exit_if_exists
echo 'settle_exit_if_exits="--exit-if-exists=/dev/root"; rm
"$job"'> /initqueue/xcat.sh
> /initqueue/work
"
Then, I added the module "xcat" into dracut.conf, and finally I
created the initrd.gz file by the "dracut" command, I also added
"rdshell rdinfo rdinitdebug" into the kernel commandline parameters,
however when the node was booting up, I couldn't see the scripts in my
own "xcat" module run.
Can anyone tell me what's wrong here? Thank you in advance. Is there
some naming restrictions in the module?

what's the output of:
$ lsinitrd <image file> | grep xcat
and please rename "premount" to something like "xcat-premount"
then you can do in the dracut shell after booting with "rdinitdebug":
$ dmesg |grep xcat
