1. The inode number is unique for every file in a File System. Do files across
file systems have same inode numbers ?

2. And how to view super-block of a file system ?

3. Is it possible for a part of a subtree of the file system in any directory to be present across two file systems ?

Sounds (to me) like homework - is it?

I am very sorry that you have mistaken this to be my homework. I am a student of Mathematics and because of sheer intrest I happen to buy some book on OPERATING SYSTEM by Tanenbaum. So if you can, Please clear my doubt. THANK YOU for responding.

Toplevel, yes ( virtual filesystems like /proc and /sys have inode 1 and root has inode 2 ) but below, no. See for yourself and compare output of 'ls -1l|sort' on two machines.


Debugfs, see "set_super_value"?


mounted /var, fdisk, new partition, mkfs, mount /new/partition, "mount --bind /new/partition/log /var/log"?


* While homework is easy to spot when the OP blatantly copies over verbage from Teh Book or copies it across fora here or elsewhere, IMHO asking the homework question is justified (and any of your fellow LQ members is allowed to ask) for a lot of technical questions where the OP only states his or her questions but doesn't offer any trace of thought or experimenting (not mandatory but it helps).

Thank you very much for your reply (and ofcourse for your patience). Since
I am a beginner for a few days I will have such ignorant doubts. I hope YOU ALL pardon me and HELP me in understanding LINUX OPERATING SYSTEM better. with love, BHANU.

No problem, you're welcome. Please don't use caps like that though, there's no need to shout, we hear you loud and clear.
