Re: Sizing your MON storage with a large cluster

Thanks, Wido -- words to live by.

I had all kinds of problems with mon DBs not compacting under Firefly, really pointed out the benefit of having ample space on the mons -- and the necessity of having those DB's live on something faster than an LFF HDD.

I've had this happen when using ceph-gentle-reweight to slowly bring in a large population of new OSDs.  Breaking that into phases helps a bunch, or setting a large -i interval.
