Hi All,
I've been using the balancer module in crush-compat mode for quite a while now and want to switch to upmap mode since all my clients are now luminous (v12.2.5)
i've reweighted the compat weight-set back to as close as the original crush weights using 'ceph osd crush reweight-compat'
Before i switch to upmap i presume i need to remove the compat weight set with:
ceph osd crush weight-set rm-compat
Will this have any significant impact (rebalancing lots of pgs) or does this have very little effect since i already reweighted everything back close to crush default weights?
Thanks in advance and kind regards,
Caspar
