I have two rbd images. running fio on them, one performs very well, and one performs poorly. I'd like to get more insight on why. I know that rbd info xx/yyy gives me a small amount of information. but I cant seem to find a detailed info dump, in the way you can do things like ceph daemon osd.9 config show I cant even get useful google hits on things like "ceph find rbd image stripe-unit" all the pages seem to detail how to set the value, but not how to query it. Can anyone point me in the right direction? -- Philip Brown| Sr. Linux System Administrator | Medata, Inc. 5 Peters Canyon Rd Suite 250 Irvine CA 92606 Office 714.918.1310| Fax 714.918.1325 pbrown(a)medata.com| www.medata.com
