Pvmove is online

Thank you so much, Torsten.

How to create the PVG1? This got confused me.

# pvcreate /dev/rdisk/disk5
# vgextend vg01 /dev/disk/disk5
# lvextend -m 1 /dev/vg01/lvol1 PVG1

[Torsten.]

Please read my previous post again, I added a line for clarification

[rescuehp17]

Thank you and steps completed until mirroring part. how to remove the old disks?

[rescuehp17]

Mirroring:

# lvextend -m 1 /dev/vgother/lvoracle pvg2

After mirroring, to remove old disks:

# lvreduce -m 0 /dev/vgname/lvname pvg1

Correct?

[rescuehp17]

Goal is, to move everything to disk140

[Torsten.]

did you extend the lvol size???

there is data on the new disk, but no mirror at all!

[rescuehp17]

Fixed that issue. Turned off the PVG-strict and that worked.

But now, how to remove the disks33 to disk43? Want all the data only on one disk, which is disk140

>> Turned off the PVG-strict and that worked.

What worked?

Not sure what exactly you did now.

How about a lvdisplay -v ...now?

And first lines of a pvdisplay -v ... too, please.

[rescuehp17]

Was able to mirror once I turn on the pvg-strict

[Torsten.]

pvg-strict means the original is in group1, mirror copy in group2.
without the mirror copy is anywhere in free space ... not on the disk you want!

depending on your settings the copy may be on the same disk - kind of useless.
