[Carlos F. Baladrón]

For data that they are in vol. log. and they are of type raw that they are in striping does not operate the pvmove already I have proven it and it does not operate. Are there any other form ?

Hi,
A way to move your data from a disk to an other is to use dd :
- Create a new lv on the target disk
- copy the lvol to the new one : dd if=/dev/vgxx/rlvolxx of=/dev/vgxx/rlvolyy bs=1024 (where lvolxx is the lv you want to move and lvolyy is the target one)
- Delete the old and rename the new one.

Hope it will help you.

dd is probably a bad move, because badspots will be a problem.

The SAFEST way is for you to backup your entire VG. delete the VG. Recreate it with the disks you want. restore your data.

Carlos,

If you want to go in the "dd" route , make
sure the disk is not being written to at that
time.

Hi Carlos,

Guess you have to use dd to copy the data from the old volume to the new volume.

Hi Carlos,
There is no risk to use dd, indeed before removing the lv source, you can test the new one.
