In this case, a Lenovo Thinkpad W530s is running OpenSUSE 12.3. cd /mntįor fs in usr var boot do umount /mnt/$fs doneģ Rescue Scenario: broken video 3.1 The Rescue Plan When that is done, reboot the system and remove the Rescue CD / USB drive! exit # "exit" from the chrootįor fs in proc sysfs bind dev/pts dev do umount $fs doneĪnd so, un-mounts are also done for the "real" filesystems. ![]() When the Rescue attempt is complete, all the chroot filesystems must be unmounted.īasically, it is necessary to (just) reverse the order of the above mounts, with umount. sudo chroot /mnt # opens a new shell, within the chroot Mount -t devpts -o rw,nosuid,noexec,gid=5,mode=620,ptmxmode=000 devpts dev/ptsįinally, "change root" to the filesystem in the chroot, to begin running Rescue commands. # if a "gnome-terminal cannot get permission" occurs, use this 'devpts' mount Now, mount the Linux "special" filesystems, in the chroot. Mount /dev/sysvg00/root /mnt # mount the root filesystem, first! # list all logical-volumes determine "role" (root, usr. Then mount all other necessary filesystems - usually var and usr, if these are separate filesystems from root. Next, mount the root and boot filesystems (if boot is separate). When this is complete, we "change root" into this mount-directory, and an operate as if this is the current, booted filesystem - including running commands for Rescue purposes.Īctivate any LVM volume-groups and logical volumes, first. ![]() The plan is to create a Linux chroot, mounted under /mnt. This is modified, from the Arch Linux rescue-doc above. 2 Prepare for the Rescue 2.1 Mount filesystems to a chroot However, that particular distro may not have all the toolset included with the System Rescue CD. Sudo mount -o loop,exec /path/to/systemrescuecd-x86-x.y.z.iso /tmp/cdromĪ fallback is a Linux distro's Rescue mode. How to copy to a USB drive, for System Rescue CD: mkdir -p /tmp/cdrom ![]() A USB thumb drive will boot and operate much faster than a CD, and will also work on Ultrabooks (desktop) and servers, without a DVD drive. System Rescue CD can be burned to CD media, or easily copied via dd to USB thumb drive. Usually, the Linux system Rescue process is not Linux distro-specific, except perhaps in the usage of a particular distro's Rescue boot, from a Live-CD, for example. It's a good idea to read several Blogs or Linux articles that have solved various Rescue issues. However, it tends to focus on a particular Rescue task, such as recovering a lost root password. Linux Recovery and Rescue documentation is available, as seen above. It is our favorite system recovery CD.1 Getting Started 1.1 Review the documentation Overall, we strongly recommend SystemRescueCd for all your system administration, system recovery, data recovery, and disk partitioning tasks. ![]() Default applications include the Midori web browser, emelFM2 twin-panel file manager, Xfburn CD/DVD writing utility, Geany IDE (Integrated Development Environment), SpaceFM file manager, ISO Master, ePDFViewer PDF viewer, Midnight Commander file manager, and much more. The distribution uses the latest stable version of the lightweight Xfce desktop environment, and it will always open a terminal emulator window every time the session starts. After booting the live media, you will be dropped to a shell prompt, where you’ll need to type the startx command in order to access the graphical environment. Another interesting feature is the ability to boot from the first or the second hard disk. Alternative kernels are also provided, just in case the standard ones don’t work as expected. Supports 32-bit and 64-bit computersĪdditionally, even if the SystemRescueCd ISO image has been designed for 32-bit architectures, users will be able to boot the system into both 64-bit and 32-bit rescue modes. SystemRescueCd provides users with an advanced boot menu, which can be used to boot the live environment in different ways, boot the currently installed operating system, or run various handy system tools (Memtest86+, NTPASSWD, SGD, FreeDOS, Netboot, HDT, AIDA, GAG, DBAN and MHDD). Several file systems utilities will help system administrators to deal with any type of filesystem task, including format, resize, move, and copy, on both Linux and Microsoft Windows operating systems. It comes with a wide range of system utilities, such as GNU Parted, GParted and partimage for disk partitioning tasks, TestDisk and GNU ddrescue for recovering lost partitions and restoring the bootable state of your boot partition. The best usage example of the SystemRescueCd distribution is data rescue after a serious system crash, when you computer won't boot anymore. SystemRescueCd is an open source Linux operating system designed for system administrators and Linux/UNIX enthusiasts who are looking for a system rescue and general system administration tool. ![]()
