I just updated master (a5eda4fcc34461dbc0fcc47448f8456097de15eb), and am
seeing OSDs failing to start:
2013-12-03 15:37:01.291200 7f488e1157c0 -1 OSD magic != my ceph osd
volume v026
failed: 'ulimit -n 32768; /usr/bin/ceph-osd -i 0 --pid-file
/var/run/ceph/osd.0.pid -c /etc/ceph/ceph.conf '
Now it appears that the magic is not being read. It is however there and
seemingly ok:
$ cat /var/lib/ceph/osd/ceph-0/magic
ceph osd volume v026
Looking at src/osd/OSD.cc I wonder if something like this is needed (as
it seems that magic is being assigned to an empty val otherwise):
--- a/src/osd/OSD.cc
+++ b/src/osd/OSD.cc
@@ -731,7 +731,7 @@ int OSD::peek_meta(ObjectStore *store, std::string&
magic,
{
string val;
- int r = store->read_meta("magic", &magic);
+ int r = store->read_meta("magic", &val);
if (r < 0)
return r;
magic = val;
This makes the osd's start ok, but the mon does not detect them
(possibly another issue or my patch is wrong). I'll keep looking :-)
Cheers
Mark
