may never complete. If you convert from a linear to a mirror and then convert that mirror back to linear /while/ the previous (up)convert is taking place, the mirror polling process will never complete. This is because the function that polls the mirror for completion doesn't check if it is still polling a mirror and the copy_percent that it gets back from the linear device is certainly never 100%. The fix is simply to check if the daemon is still looking at a mirror device - if not, return PROGRESS_CHECK_FAILED. The user sees the following output from the first (up)convert if someone else sneaks in and does a down-convert shortly after their convert: [root@bp-01 ~]# lvconvert -m1 vg/lv vg/lv: Converted: 43.4% ABORTING: Mirror percentage check failed.
