MPI not running with Scyld

Hello everyone,

I installed Scyld Beowulf 27z-8.
When I boot a slave node, here are the lines that seems errors. I also 
provide the complete log file.

eth0: 3Com 3C905C Tornado  *** INVALID CHECKSUM 002F ***
hda: no response (satus = 0xa1), resetting drive
hda: no response (satus = 0xa1)
hdb: no response (satus = 0xa1), resetting drive
hdb: no response (satus = 0xa1)

It obviously looks for hard drives though we've diskless nodes ...
Here is what the /etc/beowulf/fstab looks like:

/dev/ram3      /         ext2    fs_size=65536      0 0
none           /proc     proc    defaults           0 0
none           /dev/pts  devpts  gid=5,mode=620     0 0
$MASTER:/home  /home     nfs     defaults           0 0

Even displaying these errors, the nodes complete booting sequences and 
become UP. But if I try to run an MPI program (one of the examples)
It says, on master node:

p0_7699: p4_error: net_create_slave: bproc_rfork: -1
     p4_error: latest msg from perror: Operation not permitted
bm_list_7650: p4_error: interrupt SIGINT: 2

and on the slave nodes:

vmadump: mmap failed: /usr/lib/

Can anyone tell me what is wrong.

Thank you.

superblock could not be read or does not describe a correct ext2

is corrupt, and you might try running e2fsck with an alternate superblock:
