Hardware/software problems
5.Depending on you selection, the following occurs
-If you select Continue, the system attempts to mount your file system under the directory /mnt/sysimage/. If it fails to mount a partition, it notifies you.
-If you select
-If you select Skip, the file system is not mounted. Choose Skip if you think your file system is corrupted.
6.Once the system is in rescue mode, a prompt appears on virtual console 1 and virtual console 2 (use the Ctrl+Alt+F1 key combination to access virtual console 1 and Ctrl+Alt+F2 to access virtual console 2):
sh-2.05b#
-If you selected Continue to mount your partitions automatically and they were mounted successfully, you are in
Even if your file system is mounted, the default root partition while in rescue mode is a temporary root partition, not the root partition of the file system used during normal user mode (runlevel 3 or 5). If you selected to mount your file system and it mounted successfully, you can change the root partition of the rescue mode environment to the root partition of your file system by executing the following command:
chroot /mnt/sysimage
This is useful if you need to run commands such as rpm that require your root partition to be mounted as /. To exit the chroot environment, type exit, and you will return to the prompt.
-If you selected Skip, you can try to mount a partition manually inside rescue mode by creating a directory such as /foo, and typing the following command:
mount -t ext3 /dev/hda5 /foo
In the above command, /foo is a directory that you have created and /dev/hda5 is the partition you want to mount. If the partition is of type ext2, replace ext3 with ext2. If you do not know the names of your partitions, use the following command to list them:
fdisk -l (one)
From the prompt, you can run many useful commands such as
-
-ssh, scp, and ping if the network is started
-parted and fdisk for managing partitions
-rpm for installing or upgrading software
-joe for editing configuration files (If you try to start other popular editors such as emacs, pico, or vi, the joe editor will be started.)
