Installation with multiple Software RAID devices + LVM
I'd like to install Lenny into existing LVM volume group built top of Software RAID-1 physical volumes like this: pvs: PV VG Fmt Attr PSize PFree /dev/md0 LVM_VG_2 lvm2 a- 50,13G 0 /dev/md1 LVM_VG_2 lvm2 a- 14,80G 80,00M /proc/mdstat: Personalities : [raid1] md1 : active raid1 hda9[0] hdc6[1] 15518686 blocks super 1.2 [2/2] [UU] md0 : active raid1 hda7[0] hdc5[1] 52564544 blocks [2/2] [UU] Partitions are type fd Linux raid autodetect and autodetected fine using existing installation (mix of etch and lenny). I used priority=medium boot option to give more control during install. But Lenny installer or kernel doesn't autoassemble md1, only md0. I think it should bring md1 up too. Could it be about superblock version (md1 has version 1.2 superblock). Why version 0.90 is default? As workaround how I assemble array manually from installer without erasing data?

Mirroring existing LVM set: software RAID or LVM mirror?
I'm going to buy a second disk to add to my system. I want to mirror my current LVM setup for redundancy. So far, on older systems, I've always used software RAID 1 or 5 arrays with LVM on top. I've never had any problems with it, mainly because I've been lucky and have never had disk failures. Currently, I have no software RAID on my system yet. Just a small /boot partition, and a huge LVM partition for everything else. I recently discovered I could use LVM's mirroring capabilities. This would probably be easiest and fastest for me, since I wouldn't have to try shove a software RAID array beneath my existing PV's. On the other hand, software RAID with LVM on top seems to be the tried and trusted Linux way. I haven't even found a comparison between the two yet. Please share your LVM mirroring experiences. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]
preseed with software raid and lvm
Hello, sorry for my english: I can use preseed without problems, with raid1 and lvm separately. But at the time of using the following scheme: hd0,0 primary /boot hd1,0 primary - hd0,1 raid 1 hd1,1 raid 1 md0 lvm lv00 / lv01 swap lv02 /tmp lv03 /var I get crazy about the syntax or expert recipe that i have to use. I have read the following links (and sublinks) [0], [1],[2],[3] and i have try, in a manual installation, to read the output of: debconf-get-selections --installer file But i don't find the right way to do it. ¿any help, documentation, .cfg or tip? Thanks Inigo [0] http://d-i.alioth.debian.org/manual/en.i386/apb.html [1] http://d-i.alioth.debian.org/manual/example-preseed.txt [2] http://d-i.alioth.debian.org/svn/debian-installer/installer/doc/devel/partman-auto-recipe.txt [3] http://wiki.debian.org/DebianInstaller/Preseed

I'm not exactly sure what your goals are, but if you want to use LVM just to create partitions on the RAID1 device, there is another way. Recent 2.6 kernels have support for partitionable raid.

We don't have software RAID support in debian-installer yet, I'm afraid, but I believe efforts are underway. -- Colin Watson [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.
