Dne 3.4.2018 v 04:28 Gang He napsal(a):
Hello list,
As you know, pvmove can run on old version (e.g. lvm2-2.02.120 on SLE12SP2),
But with new version lvm2-2.02.177, I can not run pvmove successfully in the
cluster.
Here, I paste some information from my test,
if you can know the cause, please help to figure out.

Hi
Yep - it's a work in progress - if you take upstream from git - there are
already fixes committed. Hopefully next release (2.02.178) will address most
regressions cause by newer (hopefully better) code.
Good to see someone is really using it...
