Hello Heinz, Thanks for LVM. I have been using it on HP-UX and AIX and provided one can control the placing of the LV's over the disk so as to avoid excessive head movement it saves a few problems here and there. Hint: On AIX and HP-UX one can, but does not have to, control in which area of the disk an LV is placed, or even which PV's will be part of it. This allows leaving spaces between LV's which later can be used to grow them. The advantage over just making the LV bigger in the first place is that the intermediate space can be used for growing either LV at a time when one does not know which LV is going to need more space. But now my problem: I have installed LVM 1.0.1 on my Mandrake 8.0 Linux box (PIII 550Mhz, 512 MB) from the Mandrake 8.2 DVDROM. No problems. After creating boot partition, PV, VG and root/usr/var LV's on an extra disk (/dev/sdb) added to the system, I have copied the content of the boot directory to the bootpart on the new disk, root/usr/var to the new LV's, used lvmcreate _initrd to create a new boot image, copied that to the new bootpart, modified lilo.conf as suggested in the man page for lvmcreate _initrd and ran lilo and rebooted from the new FS. First time vgscan complained that LVM was not installed and suggested checking the module stuff. Indeed I could not find where in the new boot image the lvm module got loaded. I then modified modules.conf to load the LVM module on the appropriate devices ( 54 & 109 ), added the module in the appropriate place in the "lib"directory tree and tried again. The system now boots a little further, vgscan has created /etc/lvmtab and /etc/lvmtab.d, until vgchange says it can not find any volume groups. When I reboot from the existing system it is fine and all the logical volumes are accessible. Any suggestions how to proceed? Note: There is a third disk in the system (/dev/sdc/, containing the swap file system. This used to be /dev/sdb before I added the new disk. I have changed all references to the "old" /dev/sdb into /dev/sdc in /etc/fstab of the current root FS. I have also taken care that the /etc/fstab in the new root LV resembles the current situation seen from the point of view when that becomes the current root FS and that lilo.conf in the new boot/root FS is correct for the situation when in all works and the new disk becomes /dev/sda (I am taking the old drive out) Best Regards, Arie Bant. ******************************* Maes, Llandrillo Corwen, LL21 0TE United Kingdom tel.: +44 (0)1490 440 487/370 e-mail: abant@mail.com ******************************* Maes, Llandrillo Corwen, LL21 0TE United Kingdom tel.: +44 (0)1490 440 487/370 fax.: +44 (0)870 284 1575 (via e-mail) e-mail: abant@mail.com _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://www.sistina.com/lvm/Pages/howto.html
