Ceph supports OSD storage on POSIX-compliant filesystems with extended attributes. There are some edge cases that are still problematic, see the email with subject "ceph on non-btrfs file systems" that Sage just sent for a better discussion of those. I'm not sure what you mean by a filesystem "not supporting journals", the ceph-osd journal is just a file it writes to. I'm not sure what you mean by "closing the journal config"; you can disable the journal, but that will likely just make things slower; once again, using a journal is possible on any filesystem, btrfs just makes it more effective. > i tried to do that by modifying the ceph.conf file (close the journal > on osd). the mkcephfs seems ok, but when i start the service, cosd > will crash. > here's the log: > *** Caught signal (Aborted) ** > in thread 0x7f1845ce6720 > ceph version 0.34 (commit:2f039eeeb745622b866d80feda7afa055e15f6d6) > 1: ./cosd() [0x5c6304] ... > 9: (CrushWrapper::decode(ceph::buffer::list::iterator&)+0xac) [0x5611fc] > 10: (OSDMap::decode(ceph::buffer::list&)+0x8aa) [0x5622aa] > 11: (OSD::get_map(unsigned int)+0x221) [0x52f441] That sounds more like the osdmap is corrupt, somehow. Anyone else have more specific suggestions? -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
