[linux-lvm] LVM 0.9/1.0.x migration

[Hadmut Danisch]

Hi,

I just have a question:

I saw that README.1st and pvversion have vanished between
1.0 and 1.0.1-rcX. 

Does this mean that there is no way or no need to upgrade
anymore? Any disadvantages with continuing to use the old 
version?


regards
Hadmut Danisch

No need anymore.

Well, it depends what you mean with 'old'.

The newer versions have some more features but they fix a couple of bugs.
Check the CHANGELOG file in order to decide for yourself.

You no longer need to upgrade to version 2 data structures.  Newer
releases understand both formats so there's no reason not to upgrade.
Newer releases will down grade any version 2 VG's it finds when you
next *change* the metadata (eg. resize an LV).

Version 2 was bogus and resulted from my not realising that
pv->pe_on_disk.size included all the blank space upto the first PE.
Making pv->pe_start redundant.
