Rescuing a Linux System with an LVM Root File System

Logical Volumes and Red Hat Installations

Red Hat's installation program prefers to use logical volumes. If you tell the installer to use all the available disks and set up the storage automatically, you will get the following:

The first disk will have two partitions, /dev/sda1 will be of type Linux Native and /dev/sda2 will be of type LVM. The first partition, /dev/sda1, will be fairly small and will contain an Ext4fs file system. Boot loaders can read file systems but they can't handle logical volumes, so you need a file system for the kernel and the initial RAM disk image. This doesn't need to be large in Red Hat's world because they don't want you building kernels. All the other disks will have one partition each of type Linux LVM.

An Example Automatically Created LVM System

Here is an example system with three disks. VMware is providing three 6 GB IDE disk images and 1 GB of RAM. Some of the virtualized disk details have been removed from the fdisk output:

Physical Volumes and the Volume Group

All of the LVM devices have been initialized as LVM physical volumes and one volume group has been created from them. The hostname, server in this case, has been used in the volume group name.

[root@server ~]# pvscan
  PV /dev/sda2   VG vg_server   lvm2 [5.51 GiB / 0    free]
  PV /dev/sdb1   VG vg_server   lvm2 [6.00 GiB / 0    free]
  PV /dev/sdc1   VG vg_server   lvm2 [6.00 GiB / 0    free]
  Total: 3 [17.50 GiB] / in use: 3 [17.50 GiB] / in no VG: 0 [0   ]
[root@server ~]# vgscan
  Reading all physical volumes.  This may take a while...
  Found volume group "vg_server" using metadata type lvm2

You can instead use the pvdisplay and vgdisplay commands for more detail on these physical volumes and volume group.

Two logical volumes have been created from this volume group, named lv_swap and lv_root. The first of these will contain a swap partition, and will be scaled depending on the amount of RAM detected during the installation. The second logical volume, lv_root, will use all the remaining space.

That one enormous root file system makes it easy to expand storage later. Add more disks, make them physical volumes with pvcreate, then extend the volume group with vgextend, extend the root_lv logical volume with lvextend, and grow the file system with resize2fs.

You can either use the entire new disk itself as a physical volume, or you can create one full partition on it using fdisk and selecting partition type 8e for Linux LVM. Simply using the disk will be familiar to those coming from enterprise UNIX settings like Solaris, AIX, and so on. Creating IBM partition tables is something familiar from the IBM PC hardware environment.

The technology supports either approach.

The argument that I have heard for creating partitions is that a system administrator might not understand what is happening and assume that a disk without an IBM partition table contains no data and is free for other uses.

But that means that it doesn't occur to them to use the file -s command to ask what is in that device special file, or to try the pvscan command to see what is already in use with LVM. It seems to me that if you insist on creating the partitions to handle this situation, you are conceding that your system administrators don't know what they are doing. Solve the real problem instead of hoping to avoid it!

Improving File System Security
Security can be improved by splitting the storage into multiple file systems and mounting some of them in more cautious modes. These changes make it harder for an intruder to elevate their privileges. See my page on cautious file system design and use for the details on how to make those improvements.

Logical Volumes, the Device Mapper and File Systems

Here we investigate the logical volumes, what the device mapper is doing, and the mounted file systems and swap area:

In this version of RHEL, the installer uses the LVM device name for the / file system and swap device, and the embedded UUID for the /boot file system.

The Rescue Problem to be Solved

I was showing someone how to rescue a system by booting from media. We had installed the system into multiple file systems on dedicated partitions, no LVM. They asked how the rescue booting would work if the root file system was on LVM.

Someone overheard us and said "Wait, sometimes it's far worse." Is it ever, in their scenario! Here's what we came up with as a problem to solve:

The system's root file system is on LVM spread across three disks.

The system has been configured so that you must know the root password to boot to single-user mode or otherwise get into run level 1 for maintenance, a defense described here.

However, the system has not been used in some time and some former staff members have left. You no longer know what the root password is.

The system has also been configured so that you cannot break in by specifying an altenative to /sbin/init, an exploit and defense described here.

It is suspected that some boot script or critical configuration file has been corrupted or lost. Perhaps most of /etc/lvm, where we would expect to find the meta-data about the LVM devices.

All the disks were removed from the system and stored in a box. The box is labeled, and you know that it contains all of the disks. But the disks themselves were not labeled. You do not know which was disk #1, #2 and #3.

Wow. Anything else? Shall we set the disks on fire? Throw them down the stairwell? No, the above is plenty of trouble, and a worryingly realistic scenario.

The good news is that you can install that box of mystery disks in a system, boot from rescue media, and recover data from the file system. Let's start by looking at how GRUB can boot a clean system to an LVM root file system.

GRUB and Booting to an LVM Root File System

The below is the GRUB configuration file created when you let Red Hat's installer make its own choices. The enormously long kernel line has been broken here for display.

[root@server ~]# more /boot/grub/menu.lst 
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that

#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/mapper/vg_server-lv_root
#          initrd /initrd-[generic-]version.img
#boot=/dev/sda

			KEYTABLE=us crashkernel=auto rhgb quiet
	initrd /initramfs-2.6.32-71.el6.x86_64.img

GRUB cannot handle logical volumes, so /boot will be a small file system containing a "stage 1.5" module to handle that file system data structure, the main "stage 2" GRUB program, the above configuration file, and the referenced kernel and initial RAM disk image. The GRUB boot loader will find and load that kernel and disk image into RAM, and start the kernel while passing it that long list of parameters.

Notice that the root file system is specified as something that the kernel's device mapper should find. The kernel is also told about two logical volumes it should find, one of which is that one with the root file system.

Clearly, the kernel must be able to find these things on its own without reading any further configuration details, as they would be stored within the logical volume.

The above is the configuration file on the functioning system. However, that system will not boot on its own. We will boot the system from a DVD with a suitable rescue kernel and file system image. Something like Knoppix or maybe a CentOS live DVD. The rescue media will not have any information about how to find the logical volumes; it will not even know to expect them to exist.

How the Kernel Auto-Detects LVM File Systems

The BIOS finds the bootable media in the DVD drive, and its boot loader gets the kernel off the DVD into RAM and starts it. That kernel detects the disks, all of which are there although they are connected in some random order.

The disks are discovered and device-special files appear — /dev/sda, /dev/sdb and /dev/sdc. The kernel reads the first 512-byte block of each, where it may discover either a traditional IBM partition table or the more modern disk label holding a GPT or GUID Partition Table. If so, devices for the partitions appear — maybe /dev/sdb1 and /dev/sdb2, and the kernel reads the first 512-byte block of each of those.

Now, we know that /etc/lvm normally contains the meta-data about the LVM physical volumes, volume groups and logical volumes. However, that meta-data is in the file system we are trying to find, making this a chicken-and-egg problem. Plus, we suspect that that very meta-data itself has been lost or corrupted.

The kernel can still rescue the file system, because meta-data is stored in the LVM devices.

In this example scenario, it looks as though the disk currently connected as #2 was originally disk #1, and its first partition is probably a small one containing the (possibly corrupted) original /boot. The other two disks had no partition tables or disk labels, so each was simply used in its entirety as an LVM physical volume. Maybe a Red Hat install onto one disk, later followed by manual addition of two more disks.

Below is a partial hex dump of a disk partition which is part of a logical volume. Note that after the first 0x200 (that is, 512) bytes we find an LVM2 header. Just by looking through this you can see that this partition was one of three physical volumes making up a volume group named vg_server from which a logical volume named lv_root was created, and that it was created on a system running kernel 2.6.32-71.el6.x86_64.

The kernel reads this information, and its LVM and device mapper modules create a device-special file /dev/dm-0 to which symbolic links with the original names point: /dev/mapper/vg_server-lv_root and /dev/vg_server/lv_root

[root@server ~]# hexdump -C /dev/sdb2

# mount /dev/vg_server/lv_root /tmp/rescued
