Hi Frederic,

Thanks for the report!  Do you mind throwing this details into a bug
report at http://tracker.ceph.com/ ?

I have seen the same thing once before, but at the time didn't have
the chance to check if the inconsistency was coming from ceph-deploy
or from ceph-disk.  This certainly seems to point at ceph-deploy!

Hi all,

I want to alert on a command we've learned to avoid for its inconsistent
results.

on Giant 0.87.1 and Hammer 0.93.0 (ceph-deploy-1.5.22-0.noarch was used in
both cases) "ceph-deploy disk list" command has a problem.

We should get an exhaustive list of devices entries, like this one :
../..
/dev/sdk :
/dev/sdk1 ceph data, active, cluster ceph, osd.34, journal /dev/sda9
../..

But from the admin node,
when we count how many disks we have on our nodes , results are incorrect
and differ each time :
$ ceph-deploy disk list osdnode1 2>&1|grep "active," |wc -l
     8
$ ceph-deploy disk list osdnode1 2>&1|grep "active," |wc -l
    12
$ ceph-deploy disk list osdnode1 2>&1|grep "active," |wc -l
    10
$ ceph-deploy disk list osdnode1 2>&1|grep "active," |wc -l
    15
$ ceph-deploy disk list osdnode1 2>&1|grep "active," |wc -l
    12

From the nodes,
results are correct (15) and always the same :
$ ceph-disk list 2>&1|grep "active," |wc -l
    15
$ ceph-disk list 2>&1|grep "active," |wc -l
    15
$ ceph-disk list 2>&1|grep "active," |wc -l
    15
$ ceph-disk list 2>&1|grep "active," |wc -l
    15
$ ceph-disk list 2>&1|grep "active," |wc -l
    15
$ ceph-disk list 2>&1|grep "active," |wc -l
    15

but a pretty similar 'ceph-deploy osd list' command works fine
