Installed Debian Lenny using NetInst CD 5.0.3 i386 dated 20090906-12:06 onto a DELL SC1425 with two SATA disks. The system had previously had Centos 5.4 installed with LVM. The Debian installer was fighting back a little (because of this?), but eventually I picked "Guided Install with LVM" and it behaved in a plausible fashion (/dev/sda1 for /boot, /dev/sda2 for LVM, lots of partitions because I asked for them). All seemed to go fine. The system installed, and booted, I shrunk /home file system and then logical volume, then expanded /home to fit the new lv size. I add /dev/sdb1 to the only volume group, add a logical volume. Basically convinced myself LVM was working and that I could administer it. The I turned my attention to the error message that some of the commands produced: "Incorrect metadata area header checksum", since it looked annoying. I've tried a lot of things rather blindly. The first occurance is in the installer log after the message "Queuing package e2fsprogs for later installation" from "Main-Menu" so presumably in response to me using the Debian installer menu's to set up LVM. This suggests it all went pear shaped before I had the opportunity to mistype stuff at the command line. One suggestion was to install "dmraid" and look for metadata using this. It produces: /dev/sdb: ddf1. ".ddf1_disks", GROUP, ok, 155989151 sectors, data@ 0 /dev/sda: ddf1. ".ddf1_disks", GROUP, ok, 155989151 sectors, data@ 0 Attempts to erase this with "dmraid -rE" as suggested in one post fail with a three lines of: ERROR: seeking device "/dev/sdb" to 40959999737856 ERROR: writing metadata to /dev/sdb, offset 79999999488 sectors, size 0 bytes returned 0 ERROR: erasing ondisk metadata on /dev/sdb (and same for /dev/sda). Other suggestion was make sure Debian Lenny packages were upto date. They are. The netinst CD just does that now - I'm sure it didn't always do that but I double checked and no updates are available. This is my first (Linux) LVM install - be gentle. Did I fail in preparing my disks in some way? _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
