I guess I left out in my examples, where I tried rbd_cache as well, and failed # rbd config global set rbd_cache false rbd: invalid config entity: rbd_cache (must be global, client or client.<id>) So, while i am happy to file a documentation pull request.. I still need to find the specific command line that actually *works*, for the "rbd config" variant, etc. ----- Original Message ----- From: "Jason Dillaman" <jdillama@xxxxxxxxxx> To: "Philip Brown" <pbrown@xxxxxxxxxx> Cc: "ceph-users" <ceph-users@xxxxxxx> Sent: Thursday, December 17, 2020 7:48:22 AM Subject: Re: Re: bug? cant turn off rbd cache?
