Can I use the dd command ?

Can I use the dd command to copy from no striping disk to striping disk ?

Hi,

Yes you can use that. But take precaution about the target and destination sizes.

Is not it a LUN instead of a disk? As a disk can not be stripped or unstripped, rather a LUN can be.

HTH,

Hello,

Are you talking about LUN ? Yes, you can do that.

Thanks a lot.

You can also do it with mirroring.
1. add new disks to VG
2. Setup PVG to include new disks only
3. set distributed policy for VG/LV
4. mirror LVOL's
5. Adjust PVG to be the old disks
5. Split LVOL's with -b -g to have LVOL's be on new disks.
