The 'smartctl -a --json /dev/sdb' is working fine, it's just that the invocation via the ceph tell osd.X is returning nothing. This is what the OSD is doing: https://github.com/ceph/ceph/blob/master/src/osd/OSD.cc#L6250 so the possible issues I see are 1- sudo. whoever teh ceph-osd process is running as is probably not in sudoers yet 2- smartctl not in path.. on my box it's /usr/sbin, perhaps we should specify that explicitly? 3- the smart otput is failing to parse as json here https://github.com/ceph/ceph/blob/master/src/osd/OSD.cc#L6234 My money is on 1 or 2. sage > > ----- Mail original ----- > De: "Sage Weil" <sweil@xxxxxxxxxx> > À: "Rick Chen" <rick.chen@xxxxxxxxxxxxxxx> > Cc: "Jeremy Wei" <jeremycwei@xxxxxxxxx>, "brian huang" <brian.huang@xxxxxxxxxxxxxxx>, "Jeremy Wei" <jeremycwei@xxxxxxxxx>, ceph-devel@xxxxxxxxxxxxxxx > Envoyé: Mercredi 4 Juillet 2018 16:08:32 > Objet: RE: About smartctl unable to query SAS Disk device > > On Wed, 4 Jul 2018, Rick Chen wrote: > > HI Sage: > > NO, I did not see any message like ' smartctl JSON output of /dev/whatever is invalid'. > > I attached the same device smartctl command output at below. > > Oh, the other thing to keep in mind is that ceph-osd is using sudo to run > smartctl.
