lvm2 on top of dm-crypt - how to add new hard disk
Hello folks, So I might better ask before attempting something stupid. I need to add a new hard drive to an encrypted debian box. The encryption scheme was set using debian installer defaults which resulted in just /dev/sda1 - /boot outside block device encryption. Everything else is encrypted and lvm is used instead of ordinary partitions. My initial guess was that it should be possible to extend this encryption scheme to the new hard disk using standard lvm tools and the unencrypted open disk as physical volume to the already existing volume group. However, after some research the nearest I got was someone who added the disk while creating a new volume group: http://earlruby.org/2010/02/adding-an-external-encrypted-drive-with-lvm-to-ubuntu-linux/comment-page-1/ and this arch wiki saying I should better have the reverse: luks on lvm. https://wiki.archlinux.org/index.php/Encrypted_LVM#Spanned.2FMultiple_Disks But it does not state it is impossible, it just says that it requires modifying the encrypted hook. Also, it's clear that once this is done, if one disk fails, the system will be unbootable. So my question is: have anyone here ever done that?

Also, it's clear that once this is done, Yes, you could do what you're after if you had luks on lvm. If there is a way for luks to span multiple disks, I'm not aware of it. The best suggestion I can think of is to simply set the new drive up as a physical volume, and put new volume groups on it. You can mount volumes from the second drive to wherever you need more space in the original drive. If that's not possible, you should be able to move logical volumes from the first drive to the second drive to make room on the first drive. if one disk fails, the system will be unbootable. Another reason to just put a new volume group or groups on the new drive instead of extending the existing group or groups if that is possible. So my question is: have anyone here ever done that? How to I tell init to unlock both disks before mapping lvm? If you're asking how to decrypt a luks volume in place, I know of such a way. If you're asking how encrypted volumes are opened during boot, have a look at the crypttab(5) man page.

Use smartctl from the smartmontools package. If mdadm says that /dev/sdc (or cat /proc/mdstat) is at fault then use smartctl -a /dev/sdc and it will print out all kinds of info on the drive including its serial number which should be on a sticker on the case of the drive. The programs included with smartmontools might have warned you of an impending failure.

I choose fat32 becuase of it's native read/write support in Windows and Debian - ntfs could work though with ntfs-3g. You can use jkdefraggui (freeware) in XP to move all files to the start of the partition before re-sizing so the re-partitioning doesn't mess up XP. It's worked for me several times when adding Debian to an XP-only drive. Just my thoughts, take or leave as you wish. Good luck either way. Mark
Mounting new hard disk in /dev/sdb
Hello, I recently installed a new SATA hard drive on my desktop system and I noticed that Squeeze had, by default, mounted it in /dev/sda. This means that recently, due to the popular GRUB failure that caused everybody (including myself) a lot of grief, my Debian disk rescue mode was installing the new GRUB on (hd0), which was, however, on the brand new disk (NTFS formatted), which does not hold and will not hold any operating systems. Thus, I was still seeing grub_printf_ as missing when I logged in. So I was just wondering whether there was any way that I could plug in my new hard drive and mount it on /dev/sdb, so that I can access it as (hd1) in GRUB notation, next time the boot loader fails (which, I have to say, has been reather frequent lately). Thanks, Jason

What appears where in /dev is a function of your BIOS, the kernel, and udev. If it's IDE, ATA, or ATAPI it shows up as a /dev/hd. And those seem to be nicely mapped to IDE controller number / master / slave. Unless it's serial-ATA, of course, in which case it's a /dev/sd :-/ All SCSI, SATA, and USB are a /dev/sd -- which sd depends on what your BIOS sees first at boot. My (Dell) servers look at the USB ports first, so a USB stick becomes /dev/sda. Then it looks for SATA, and finally SCSI. The Sun box looks at SCSI first... So when my grub config said to load / off /dev/sdan (Debian lenny installer default), and I accidentally left a USB stick in one of the ports, the machine wouldn't boot. I don't remember if (hd0) was hosed as well. Oh. And the /dev directory is created by udev these days. It can name things anything it wants. /rant It's much more repeatable to specify the filesystem's UUID (vol_id /dev/sd??) instead of the device node. In both grub's config and in fstab.

Can't mount a newly created ext3 partition from the new Hard Disk I installed...
I bought a Western Digital 80GB Hard Disk as a second disk for my GNU/Linux Debian system (kernel 2.6.8-2-386). I attached it as a Slave and set its jumper accordingly. The next step was to create partition, and I created one by running (under root of course) 'fdisk /dev/hdb' and using the command new (n) to create a primary partition with partition number 1 for which I only used 12GB (of 80GB available). Also with command 't' I made sure the filesystem is ext3 (code 83). I created a directory /music on which I plan to mount this filesystem. Then I went to change my fstab file which now looks like this: # /etc/fstab: static file system information. # # file system mount point type options dump pass proc/proc procdefaults0 0 /dev/hda1 / ext3defaults,errors=remount-ro 0 1 /dev/hda2 /localdisk ext3defaults0 0 /dev/hda5 noneswapsw 0 0 /dev/hdb1 /music ext3defaults0 0 /dev/hdc/media/cdrom0 udf,iso9660 ro,users,noauto,unhide 0 0 /dev/hdd/media/cdrom1 udf,iso9660 ro,users,noauto,unhide 0 0 /dev/sda/media/usb0 autorw,users,noauto 0 0 /dev/sda1 /media/usb1 vfatrw,users,noauto 0 0 shmfs /dev/shmshm defaults 0 0 I restarted my system and the filesystem was not mounted.

Thanks Mike! I've done it.
Are you saying that you have now run mkfs and it mounts?
If so, then congratulations!
Or are you saying that you just omitted to mention that you
already ran mkfs, but it doesn't mount?
If so, then I'm as mystified as you are.

Thanks, you guys! It was my first time posting a question on this maling list...and what an overwhelming response :)! Yeah, i also confirmed from one of my co-workers (an ardent follower of Debian) that there is no way to extend the partitions unless the current disk was setup using logical volume management; which in our case it is not. ok so i would have to look into your various suggestions. hopefully i will have a success story to recount pretty soon :) /Anita __ Do you Yahoo!?

Logical Volume Manager adds a layer between the physical hard disk and the file system. For more detailed information I would suggest you read the HOWTO here: http://www.tldp.org/HOWTO/LVM-HOWTO/index.html If LVM were used then the only down time would be when the machine was actually turned off and the new hard drive was added. Once that's done it's quite quick when compared to moving the data across to put the new disk into use. Once again I suggest the HOWTO as it explains it much better then me :-) I use LVM at home and when I run out of space on one partition I just more from the spare space on another partition.

I do not think you can actually extend the existing partitions - that is make them span the old and the new disks. However. you can install the new disk, use fdisk to create partitons on it and then move the data from some of the existing partitions to the new disk. Then you can mount the new partitons. This way you could, for instance, create a larger /home or /var or /usr etc. on the new disk to replace the partitons on the old disk. Once this is done, you could delete the old partions and use a tool such as parted or QTparted to resize the partitions on the old disk and make them larger also.

cloning my debian install onto my new hard disk?
I would like to copy my entire install onto my new larger hard disk, then set it up to boot there. I have the old disk as master and the new as slave, and I've mounted the slave and used cp -a on the top level directories. The cp -a of 'initrd' directory complained a bit though, and I'm not sure what steps are best to take to make the new drive the one that gets booted from/mounted as root. Does anyone have software to recommend other than cp? What should I do after cp to make initrd setup work right? A report of a recend (good) experience with this task would be greatly appreciated.

Does anyone have software to recommend other than cp? What should I do after cp to make initrd setup work right? A report of a recend (good) experience with this task would be greatly appreciated.

Moving selected file systems to new hard disk
I had kept a copy of a really great article posted on another mailing list for this but now seem to have lost it. I would like to upgrade and move things like /home and /usr to a new scsi hard disk drive which has much more room. The old disk is /dev/sda and I am installing a new IBM 18 gig scsi drive to /dev/sdb. I would definitely like to get /home there since it seems to grow quite quickly. If /usr could move also, that would be cool. -- Michael Perry [EMAIL PROTECTED] --

Create the new partitions on /dev/sdb, then mount each partition under /mnt. Go to the directory you want to move, the example shows /usr, but /home, /var and such should be the same. I was told there was some issue with sockets not moving correctly with tar, but I don't know what a socket is, and I was able to move /usr with no issues. As I am new to Linux as well, I asked for, and got a very good explanation of what this command did. After I had moved the directories, I just needed to update /etc/fstab to mount the new partitions under the proper directories. I'm still waiting to copy and resize my root partition. cd /usr tar cpf - . | (cd /mnt ; tar xpf -) tar: you know this c : create p : preserve permisions (rwx and owners, etc) f : file name, the next arg will give the name of the file - : most commands understand this to mean stdin/stdout. tar is one, so this is stdout. . : the current directory. if you make a tar file of . and then do a tar t of it, everything will look like ./foo, ./bar, ./zoo/cow, and so on. an ls -a will show both . and .. dirs. the parenthesis around the other two commands force them into a subshell, so it's almost like piping into a shell script. that way the cd command takes effect, and that's also why the cd doesn't affect your current session - at the end of this command you'll still be in /usr.

Re: New Hard Disk
I'm trying to add space to my system and all i have is a 170meg HD what I want to do is move everything from /usr/lib to the new HD and have the new drive mount at that point. I would like to have the move done in one command. is that posible or will i have to move the whole tree by hand? Sure.. Mount the new partition under /mnt, then: (get into single user mode) cd /usr/lib tar -cvO . | (cd /mnt ; tar -xpf - ) (Now check the files and perms under /mnt, and make sure it's ok) cd /usr/lib (in case you left there...) rm -rf * I'd suggest that, before removing the files, update fstab (as below) to mount the new drive to /usr/lib and then reboot and see if everthing works. i.e. check files/permissions under /usr/lib. In this situation, the new drive (and files) are mounted right over top of the existing directory structure. (BTW, as a tip, this is a great way to hide a directory structure on your system from prying eyes Drop some files into a directory and then mount something over top of it. Poof! The files are gone until you need them and access them.) Once you know things are working, then unmount the new fs from /usr/lib, remove the existing structure, and then remount the fs.

Re: New Hard Disk
Syd -- Looks like you can use the cp command with the --archive option (see cp man page). What you need to do is, after you place a linux filesystem on the partition with mke2fs, mount that partition under the generic mount-point directory /mnt: mount /dev/hd?? /mnt Then, copy everything from /usr/lib onto the partition: cp --archive /usr/lib /mnt Once you're sure everything has been copied and is intact, erase everything under /usr/lib: rm -r /usr/lib/* Then umount the partition, and remount it under /usr/lib umount /mnt mount /dev/hd?? /usr/lib Be sure to place the necessary data in your /etc/fstab file so that the partition gets mounted at boot time from now on (/etc/fstab format is self-explanatory). Drop me a line if you have problems, or this procedure doesn't work out (be sure to back up your files before doing this!). Hope it works! :-) -- Harmon -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word unsubscribe to [EMAIL PROTECTED] . Trouble? e-mail to [EMAIL PROTECTED] .
