Bug #17685
Updated by Kefu Chai over 7 years ago
I think there is still a bug in the "osd metadata" reporting in 10.2.3 - the JSON structure returned is not terminated when the OSD is added but not running or added to the crush map yet. Its an odd condition to get into, but when adding a disk and there is an issue that causes it to fail to complete the add operation such as when the permissions in the /var/lib/ceph/osd/osd/XXX are incorrectly set to root:root instead of ceph:ceph, the metadata output does not terminate with the final closing bracket "]". Here is the end of the (truncated) output from "ceph osd tree" showing the disk just recently added but without any weight and marked "down". <pre> -2 130.67999 host ic1ss06 0 3.62999 osd.0 up 1.00000 1.00000 6 3.62999 osd.6 up 1.00000 1.00000 7 3.62999 osd.7 up 1.00000 1.00000 13 3.62999 osd.13 up 1.00000 1.00000 21 3.62999 osd.21 up 1.00000 1.00000 27 3.62999 osd.27 up 1.00000 1.00000 33 3.62999 osd.33 up 1.00000 1.00000 39 3.62999 osd.39 up 1.00000 1.00000 46 3.62999 osd.46 up 1.00000 1.00000 48 3.62999 osd.48 up 1.00000 1.00000 55 3.62999 osd.55 up 1.00000 1.00000 60 3.62999 osd.60 up 1.00000 1.00000 66 3.62999 osd.66 up 1.00000 1.00000 72 3.62999 osd.72 up 1.00000 1.00000 75 3.62999 osd.75 up 1.00000 1.00000 81 3.62999 osd.81 up 1.00000 1.00000 88 3.62999 osd.88 up 1.00000 1.00000 97 3.62999 osd.97 up 1.00000 1.00000 99 3.62999 osd.99 up 1.00000 1.00000 102 3.62999 osd.102 up 1.00000 1.00000 110 3.62999 osd.110 up 1.00000 1.00000 120 3.62999 osd.120 up 1.00000 1.00000 127 3.62999 osd.127 up 1.00000 1.00000 129 3.62999 osd.129 up 1.00000 1.00000 136 3.62999 osd.136 up 1.00000 1.00000 140 3.62999 osd.140 up 1.00000 1.00000 147 3.62999 osd.147 up 1.00000 1.00000 155 3.62999 osd.155 up 1.00000 1.00000 165 3.62999 osd.165 up 1.00000 1.00000 166 3.62999 osd.166 up 1.00000 1.00000 174 3.62999 osd.174 up 1.00000 1.00000 184 3.62999 osd.184 up 1.00000 1.00000 190 3.62999 osd.190 up 1.00000 1.00000 194 3.62999 osd.194 up 1.00000 1.00000 202 3.62999 osd.202 up 1.00000 1.00000 209 3.62999 osd.209 up 1.00000 1.00000 173 0 osd.173 down 1.00000 1.00000 </pre> Now when I run "ceph osd metadata", note that the closing "]" is missing. <pre> $ ceph osd metadata [ ...
