Hi. > Can you cat the /sys/kernel/debug/ceph/*/mdsc and osdc files? Ok, I've re-ran again, the freeze reproduced! updated here http://tracker.newdream.net/issues/479 > The cosd --mkfs step will clear out old data. mkcephfs wouldn't get the --mkfs, I see now. ;) > The 'btrfs path' is the mount point, which defaults to the same as 'osd > data'. It doesn't affect anythign in your case, though. The real > question is where the EOPNOTSUPP is coming from. Is /data/osd0 a btrfs or > ext3/4 file system at this point? I made sure to mount dir empty, get the disk all empty, and mount with user_xattr, so I no longer gets the above error, thanks. my plan is to first get the ceph working in a good performance order before moving to btrfs Thanks a lot. -- 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
