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.
Do you have a schedule for next release (2.02.178)? pvmove is a good feature, I
hope we can support it in our next SLE release.
By the way, some customers really used this feature, but it did not look very
stable,
especially when users did pvmove during the (clustered) LV is being used for
reading/writing.
Thanks a lot.
Gang
Good to see someone is really using it...
