Hi All, I've got some alleged errors during OSD startup: ceph-osd-prestart.sh[29360]: ERROR:calamari_osd_location:Error 2 running ceph config-key get:'Error ENOENT: error obtaining 'daemon-private/osd.0/v1/calamari/osd_crush_location': (2) No such file or directory' The above appears twice, but doesn't seem to actually cause any harm (the OSD starts fine). Manually invoking `/usr/bin/calamari-crush-location --id 0 --type osd` gives the same errors, but *does* print "host=ses2-1" (the default host in my case) to STDOUT. The errors are there because "daemon-private/osd.0/v1/calamari/osd_crush_location" was never set by anything, so can't be found by `ceph config-key get`. AFAICT the only time this *would* be set is if someone has used the calamari REST API to move an OSD in the CRUSH map (this functionality doesn't seem to be exposed in Romana), and then only if they were operating on the immediate parent node of an OSD (or some OSDs). So, my question is, what's the point? `calamari-crush-location` will only return data from "daemon-private/osd.$ID/v1/calamari/osd_crush_location" if the stored location is on the current host, but under what real-world circumstances would "daemon-private/osd.0/v1/calamari/osd_crush_location" exist and include anything other than a hostname anyway? I'm obviously missing something, but it looks like the whole thing essentially amounts to a NOOP with some annoying error messages :) Thanks, Tim -- Tim Serong Senior Clustering Engineer SUSE tserong@xxxxxxxx -- 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
