Re: File system mount issue

[Saket Sinha <saket.sinha89@xxxxxxxxx>]

Even even when I try 

mount   -t    HEPunion    none    /mnt/sak

I get the same error. Is it something to do with my driver code? I mean I have implemented the system call for mounting the fs then why such an error is coming?

Your file system has nodev in fikesystems soo it does not require block device. Try none instead /dev/sda1

As suggested

now when I do-

mount -t HEPunion    /dev/sda1    /mnt/sak

Now I am getting an error message-

mount:wrong fs, bad option, bad superblock on /dev/sda1, Missing codepage or other error.

What does "cat /proc/filesystems" says after you insert your module?

thanks,
