Hi, there is a memory allocation bug, at least in hammer. Mouting an rbd volume as a block device on a ceph node might run you into that. Then your mount wont work, and you will have to restart the OSD daemon(s). Its generally not a perfectly good idea. Better use a dedicated client for the mounts. -- Mit freundlichen Gruessen / Best regards Oliver Dzombic IP-Interactive mailto:info@xxxxxxxxxxxxxxxxx Anschrift: IP Interactive UG ( haftungsbeschraenkt ) Zum Sonnenberg 1-3 63571 Gelnhausen HRB 93402 beim Amtsgericht Hanau Geschäftsführung: Oliver Dzombic Steuer Nr.: 35 236 3622 1 UST ID: DE274086107 Am 29.04.2016 um 17:30 schrieb Edward Huyer: > This is more of a "why" than a "can I/should I" question. > > The Ceph block device quickstart says (if I interpret it correctly) not to use a physical machine as both a Ceph RBD client and a node for hosting OSDs or other Ceph services. > > Is this interpretation correct?
