[linux-lvm] How to upgrade old LVM version.

[linux-lvm] How to upgrade old LVM version.

[Dick Middleton]

Hi,

    I'm currently running LVM 0.9.1_beta6 on Debian 2.2 with kernel 
2.2.19 and have been trying
for some time to upgrade to something more recent.

Whenever I try this I find that vgscan from any newer version of LVM 
hangs (without
error messages) - I'm forced to reboot.  The only evidence I can find is 
if I run pvscan.  
This reports "different structure size".

I currently have all my filesystem including root running on LVM on top 
of software RAID so
it's a fairly delicate business mucking about with this.  I'm looking 
for  a way to fix the problem
other than decanting everything to tape and starting from scratch again.

I do have a separate bootable disc with 2.4 kernel and LVM 1.0 which I 
can use as a stepping
stone but so far this too hangs as soon as vgscan is run.

Any advice would be appreciated.

Dick

vgscan coming with a newer LVM version should scan your disks fine.
Tha fact that it hangs could refer to an empty CDROM or the like scanned
and a large timeout involved.

Running "vgscan -d" should find the relevant 'candidate'.
If so, temporarily inserting a valid CD or removing the /dev/ entry
could help it.
