[linux-lvm] Request for misalignment tests

[Heinz Mauelshagen]

All,

we need your help in regard to the misalignment problems we are trying
to fix right now in order to get facts concerning how many people are actually 
suffering from it.


In case you created VGs or extended them with LVM 0.9.1 Beta 6 or 7,
we'd appreciate if you could send us the output (if any) of

   pvdisplay -v /dev/YourPVname | grep "^ *00000"

if the sector offset in the last column is odd.

If so, please add a "pvdisplay /dev/YourPVname" as well.

We appreciate your help!

Regards,
Heinz      -- The LVM guy --

Jorg,

please avoid recent CVS and if possible don't create PVs with
LVM versions > 0.9.1 Beta 5.

Sorry for the incenvenience.

What if we have already done this some month ago?  Is it enough to avoid
pvmove until everything is fixed?  Will there be a tool to fix bad PVs in
use?

It can only have hapend after 0.9.1 Beta 6 came out in March.
My provided one liner test shows you if it is the case then.

> pvmove until everything is fixed?

After it is fixed and your installation is update to the next LVM release
yuu should be able to pvmove PEs to other (temporary) PVs which are created
with new tools and correct alignment.

This is going to be a _major_ PITA here.  March to July is a long period.  I could live
with a tolleration mode.   Everything on my system is in LVM (excepting a small recovery
partition).  My largest PV is corrupted...

Hopefully something can be done to make this beta error a little less painfull - Please.

TIA,

Ed Tomlinson
