Hi Brett,
this issue has been with you long before upgrade to 14.2.1. This
upgrade just brought corresponding alert visible.
You can turn the alert off by setting
bluestore_warn_on_bluefs_spillover=false.
But generally this warning shows DB data layout inefficiency -
some data is kept at slow device - which might has some negative
performance impact.
Unfortunately that's a know issue with current RocksDB/BlueStore
interaction - spillovers to slow device might take place even when
there is plenty of free space at fast one.
Thanks,
Igor

Does anybody have a fix for BlueFS spillover
detected? This started happening 2 days after an upgrade to
14.2.1 and has increased from 3 OSDs to 118 in the last 4 days.
I read you could fix it by rebuilding the OSDs, but rebuilding
the 264 OSDs on this cluster will take months of rebalancing.
