3. Logical block size is the size of the blocks that the
system kernel uses to read or write files. The logical
block size is usually different from the physical block
size, which is the size of the smallest block that the disk
controller can read or write, usually 512 bytes.
To Find out Physical Block Size
dumpe2fs <some device> | grep -i 'Block size'
4. Daemon at NFS Server: portmap,NFSD,rpc.mountd
Clinet End : rpc.mountd

Answer / sivakumar
ANS 6 :
An inode is a data structure on a Unix / Linux file system.
An inode stores basic information about a regular file,
directory, or other file system object. You can use
following two commands to display an inode:
[a] ls command : list directory contents
[b] stat command : display file or file system status
eg : # stat /etc/passwd
Output:
File: `/etc/group'
Size: 566 Blocks: 16 IO Block: 4096
regular file
Device: fd00h/64768d Inode: 2443679 Links: 1
Access: (0644/-rw-r--r--) Uid: ( 0/ root) Gid: (
0/ root)
