Description Corey Marthaler 2014-08-07 19:31:57 UTC
Description of problem:
This is a super low priority rfe, but currently 'lv_converting' only reports the conversion of existing mirrors to greater legged mirrors. It does not report the conversion of linears -> mirrors, raids, or the down conversion of mirrors or raid volumes.

Comment 2 Peter Rajnoha 2015-10-15 12:31:59 UTC
The issue here is that the LV_CONVERTING flag is only used in subset of situations where the conversion actually happens (maybe the LV_CONVERTING is not the happiest name for the flag), not covering the downconversion and conversion from linear to mirror/raid.

We need more than looking at the LV_CONVERTING flag when reporting the lv_converting field. I haven't looked at the code around yet so I'm not yet sure how straightforward the change is here but I suppose we should be able to tell which LV is now being changed.

I'm acking this one, but considering the low priority of this issue, it may end up postponed if preemted by any other priority work that appears.
