More banging on my prototype cluster, and ran into an odd problem. Used to be, when I create an rbd device, then try to map it, it would initially fail, saying I have to disable some features. Then I just run the suggested disable line -- usually rbd feature disable poolname/rbdname object-map fast-diff deep-flatten and then I can map it fine. but now after the latest cluster recreation, when I try to map, I just get # rbd map testpool/zfs02 rbd: sysfs write failed In some cases useful info is found in syslog - try "dmesg | tail". rbd: map failed: (110) Connection timed out and no errors in dmesg output if I try to disable those features anyway, I get librbd::Operations: one or more requested features are already disabled(22) Invalid argument nothing in /var/log/ceph/cephadm.log either Any suggestions? -- 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@xxxxxxxxxx| www.medata.com _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
