Mounting with an alternative superblock
Asked by Steve Rowse
Q. After reading your tip about superblock I am just wondering How do I mount file system with an alternative superblock (Linux ext3 file system).
A. Mount command by default use block 1. However you can force mount to use specific superblock. Use following syntax:
mount sb=alternative superblock. /dev/sdaX /mnt
OR
mount sb=alternative superblock. /dev/hdaX /mnt
Thus, if you want to use logical block 32768 on a filesystem with 4k blocks, use "sb=131072", type command as follows:
# mount sb=131072 /dev/hda2 /mnt
