Re: pvmove thin volume doesn't move

Right,=C2=A0 so LVMThin(1) conveniently omits "Oh BTW standard functionalit=
y like pvmove() is not implemented."

lvmthin is a sub-set or sub-class of LVM, therefore any reasonable person w=
ould assume all functionality cascades down. Because it pretty much does fo=
r everything else.

And any reasonable person would assume lvmthin would have implemented the n=
ecessary hooks so that pvmove() would work by lvmthin handing lvm back a li=
nked-list of all of the pieces in the correct order so they could be writte=
n to lvm(thick) or to another lvmthin pool. This is not that big of a cogni=
tive leap.

That Linux LVM thin is missing "obvious" functionality is fine, it just nee=
ds to be stated very clearly.
