Nfs over Ceph is probably a bad way to go. Ceph works natively with ACS, better to put efforts finding why you have isdues with that.
Also, with Ceph short qd small objects write IO performance will be low without proper fine tuning, writeback caching and pretty high amount of OSDs... thats why I use simple local storage everywhere. чт, 23 сент. 2021 г., 17:18 Mevludin Blazevic <[email protected]>: > Hi all, > > very interesting discussion here.
