[DRBD-user] How to migrate from HDDs to SSDs?

[Daniel Ulman]

Hi Den,

Thank you for your answer.

I use LVM but "pvmove" says that the SSD does not have enough space to move the PV

Thank you again

Daniel

Hello,

if you use lvm, another way could be to add the ssd to the same 
volumegroup and use pvmove for LVs

never tried...
