Thank you for the excellent explanation! http://www.gagme.com/greg/linux/raid-lvm.php from this link I read The maximum number of physical extents is approximately 65k so take your maximum volume size and divide it by 65k then round it to the next nice round number. looks like I already have Total PE 953799 this is bigger than 65k, does anyone know the current maximum number PE in debian lenny?

root on LVM problem on etch
Wasn't sure where to raise this. I used to run a sarge system with root on LVM volume on raid1. ( I don't think raid is relevant here but mention it for completeness). When I upgraded to etch the upgrade seemed to go OK but the system wouldn't reboot. It appeared that the LVM volume wasn't activated. I couldn't sort the problem out and was under time pressure so did a clean etch install without LVM. I've now tried to move back to root on LVM on raid and hit the same problem. After some playing around the problem seems to be my root= parameter in Grub. I have always specified a LVM volume as /dev/vg/lv and this worked fine on Sarge. On Etch it seems you have to use /dev/mapper/vg-lv. Can't be sure that this is exactly the same issue I had on the upgrade but seems likely. This may be documented somewhere but couldn't find it - if it is, apologies. Regards Tony Middleton. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?

Re: 2.6 LVM problem
Did you see the LVM 2 faq? http://www.ibiblio.org/mdw/HOWTO/LVM-HOWTO/lvm2faq.html. I learned the hard way, that it is not a good idea to convert your meta data format from lvm1 to 2 till you can boot with at least 1 good kernel with lvm2 support. It is always best to only change one thing at a time, but I thought it was more trouble than it was worth getting 2.4 going with lvm2 support, especially since lvm2 is backwards compatible. Other than that it was pretty easy, install 2.6.5 with device mapper support. Install lvm2. Boot, fix fstab to new mount points. Reboot. I hit a bug (now fixed) that caused the lvm script to fail. /Allan -- Allan Wind P.O. Box 2022 Woburn, MA 01888-0022 USA signature.asc Description: Digital signature

2.6 LVM problem
I have a box which runs 2.4.22 just fine but wanted to try out 2.6.5 as some of the extra features from 2.6 would be very welcome. The box has several normal partitions (ReiserFS) and one partition that is configured with LVM (for future expansion, at the moment it's just one partition on the main HDD). Compiling and installing the 2.6.5 kernel was fine. However, when I came to run lilo after adding the entry for the new kernel in lilo.conf, I got the following message: /dev/mapper/control: open failed: No such device Is device-mapper driver missing from kernel? Warning: '/proc/partitions' does not match '/dev' directory structure. Name change: '/dev/lvma' - '/dev/vg00/mythtvlv' Added 2.6.5 Added 2.4.22-HT * Device mapper is installed in the kernel. Some googling showed that this was the sort of message that people using DEVFS in their kernel experienced. I'm not using DEVFS however. Rebooting and selecting the new kernel resulted in the machine booting just fine, but the lvm partition wasn't mounted. The error during bootup was: mount: /dev/vg00/mythtvlv is not a valid block device Can anyone tell me what is going wrong here? I can post my .config for my kernel if that would help.

Vorher Manpage lesen und einen -test machen. danke erstmal fuer den hinweis. die manpage beschreibeung ist leider etwas unzureichend: vgcfgrestore restores the volume group descriptor area from backup files in /etc/lvmconf or from VGConfPath to the given initialized (see pvcreate(8) ) PhysicalVolumePath. The default backup file is /etc/lvmconf/VolumeGroupName.conf. This command DOES NOT restore data contained in logical volume(s), only the LVM configuration metadata! da steht zwar drin, dass die Daten nicht wiederhergestellt werden, aber leider *nicht*, ob sie denn uebernommen werden sofern nicht geloescht. sollte das logical volume wiederhergestellt werden und sind keine daten drauf, dann bringt das auch nicht so furchtbar viel. bei google gibt es einen ganzen eintrag zum stichwort 'vgcfgrestore' ;-) -- Benjamin Zeiss GPG Public Key: http://www.kellnerweg.de/~bzeiss/pubkey.asc Mal ein klein wenig Ursachenforschung: Hast du was am System geändert, bevor du neu gestartet hast?

lvm problem
Hallo, ich habe ein LVM Problem mit meinem Linux Desktop. Auf dem System ist Debian Woody installiert. Der Rechner ist always on. Nun musste ich neulich doch mal neustarten und dann lief der Rechner nicht mehr hoch, indem er meinte er könne mein /dev/vg01 (das ist die LVM volume group) nicht aktivieren; gefunden hat er es mit vgscan, aber das vgchange -a y verweigert mit vgchange -- ERROR: can't get name(s) of physical volumes vgchange -- Please check, if /proc is mounted den Dienst. Mein /proc ist gemountet und in /proc/lvm /global steht: Total: 0 VGs 0 PVs 0 LVs (LVs open) Global: 152 bytes malloced IOP version 10 0:05:06 active Bei der Recherche auf Google habe ich immer wieder gefunden, das dieses Verhalten mit devfs zusammenhängt, dieses benutze ich aber nicht. Auch das /dev Verzeichnis ist da und funktioniert. Das LVM für meine Homeverzeichnisse (/home) besteht aus zwei Partitionen /dev/hde4 und /dev/hdg1 Auf /dev/hde3 ist / gemountet. Ein Hardwarefehler schliesst sich also aus. Wenn ich /home aus der /etc/fstab austrage, dann läuft der Rechner hoch und root kann ganz normal arbeiten. Die User natürlich nicht, da deren Homeverzeichnisse fehlen ja. Einen Dump des Debugging vgchange findest Du unter: http://www.kellnerweg.de/~dz/vgchangedump Gibt es einen Weg das LVM wieder zu aktivieren _ohne_ Datenverlust?
