tschwenke Posted October 31, 2005 Report Share Posted October 31, 2005 (edited) Well, after my 2006 install on a new drive, I now have 2 old 40Gb drives sitting in the machine. I was manaully mounting them as necessary to get stuff off them. Now what I would like to do is wipe them both out and make them one volume group (VG) so that they appear as 80Gb of space. Can I use MCC and the Partition manager to do this? Do I just creat a partition as ext3 and not mount it and create the group after that? Any help for a newbie would be appreciated. I think 2006 has the capability to do this built in? SEE LAST POST Edited November 7, 2005 by tschwenke Quote Link to comment Share on other sites More sharing options...
scarecrow Posted October 31, 2005 Report Share Posted October 31, 2005 In theory it *can* be done, but in practice it can be not so easy... are these two drives IDENTICAL or not? Quote Link to comment Share on other sites More sharing options...
tschwenke Posted October 31, 2005 Author Report Share Posted October 31, 2005 hdc: Maxtor 6L040L2 hdd: Maxtor 6L040J2 close to being the same. From stuff I read it sounded like LVM was there during the initial install (since maybe version 9.2). What, if I didn't do it then, I screwed myself?

scarecrow Posted October 31, 2005 Report Share Posted October 31, 2005 These two drives are "almost" identical, AFAIK their only difference is the bearing mechanism- else their geometry is absolutely matching each other. You can setup LVM after the installation ( here is a decent general guide), but there must be a more automated procedure via Mandriva Control Center. No Mandy handy ATM, and I've never set a LVM on mandy before, but if you wish I can search for more distro-specific instructions. Quote Link to comment Share on other sites More sharing options...

tschwenke Posted November 7, 2005 Author Report Share Posted November 7, 2005 What am I missing?? So on Sunday I figured I would tackle reading the LVM 2 FAQ and see what I could get done. Well first I found that the LVM2 and DMSETUP modules were in the RPM setup so I installed thoses. After installing, everything went smooth. I haven't used dmsetup for anything, and after the lvm2 install the /dev/mapper directory was already created. I could also use all the tools... So. 1. I formatted my 2 disks as ext3 with DiskDrake 2. did pvcreate on both (/dev/hdc1 and /dev/hdd1) 3. did vgreate including both above 4. lvcreate -l 19082 myvg -n mylv 5. vgchange -a y myvg after this it told me that 1 logical volume in 'myvg' now active So things were looking promising... But now, how do I mount it! mount /dev/myvg/mylv /data2 => you must specify the filesystem type mount -t ext3 /dev/myvg/mylv /data2 => wrong fs type, bad option, bad superblock on /dev/... dmesg | tail => VFS: can't find ext3 filesystem on dev dm-0 Any help?? Seems so close. pvdisplay, and lvdisplay all look good. The directory properties for /dev/myvg are different than others, that is the only thing I see right off, but then again, I am now lost!

crazyspongebob Posted November 20, 2005 Report Share Posted November 20, 2005 I have 3 hard drives of different sizes but use LVM to make them into one big virtual hard drive. They are two different 80 Gig Western Digital and one 200 Gig Hitachi. I make them into one LVM volume then create partitions on it. With the exception that I reserve about 150 MB on the first hard drive for the boot partition so that I install the bootloader. J.T. Quote Link to comment Share on other sites More sharing options...
