I have a superblock read failure at boot time, I’m asked to type the root password and I managed to browse the root / partition, that was the only one that the system was able to mount. I just stumbled on this page and I would like to thank because I think it is really what I need :) Or by label, using -L label or by uuid, using -U uuid. One can also mount an already visible directory tree elsewhere:Ī device can be given by name, say /dev/hda1 or /dev/cdrom, Note that one does not really mount a device, one mountsĪ filesystem (of the given type) found on the device. Mount -t type dev dir : ordinary mount command Mount directory : mount known device here Mount device : mount device at the known place Mount -a … : mount all stuff from /etc/fstab The command is `mount something somewhere’.ĭetails found in /etc/fstab may be omitted. instead i was seeing help of mount command I could not mount the fs when the system was live. I believe we will be able to mount the fs using a diff super block “only” if we r running system in rescue mode with cd media mounted, If you made an ext3 filesystem, you would use: Now, remember when using this command, you need to use the same flags you used when you created the filesystem originally, and just add ‘-n’ to them. This is making the utility you used to create the filesystem tell you where the backups are. ? Was this helpful?

You should always keep backup of all important data including configuration files. You can also use superblock stored at 32768 to mount partition, enter: Now try to mount file system using mount command: dev/sda2: ***** FILE SYSTEM WAS MODIFIED ***** Pass 5: Checking group summary informationįree blocks count wrong for group #241 (32254, counted=32253).įree blocks count wrong for group #362 (32254, counted=32248).įree blocks count wrong for group #368 (32254, counted=27774).

Pass 1: Checking inodes, blocks, and sizes dev/sda2 was not cleanly unmounted, check forced. Now check and repair a Linux file system using alternate superblock # 32768: Mount partition using alternate superblockįind out superblock location for /dev/sda2: At boot: prompt type command linux rescue).

If your system will give you a terminal type the following command, else boot Linux system from rescue disk (boot from 1st CD/DVD. WARNING! Make sure file system is UNMOUNTED.
