Hi,
Yesterday I got a notification that a RGW setup was having issues with
objects suddenly giving errors (403 and 404) when trying to access them.
I started digging and after cranking up the logs with 'debug rados' and
'debug rgw' set to 20 I found what caused RGW to throw a error:
librados: Objecter returned from getxattrs r=-2
Using "ceph osd map .rgw.buckets <object>" I found which OSDs were
primary for that object's PG and I saw that they all came from one
machine which got a clean shutdown and start just 24 hours before that.
After taking that machine out of production the other OSDs took over and
RGW started serving the objects again, but I'm confused.
The underlying filesystem is XFS and all 6 filesystems were clean and
healthy. Like I said, the machine only got a clean shutdown 24 hours
before that due to a physical migration, but that's all.
Did anybody see this before? Suddenly the xattrs for those objects were
gone.
This was with Ceph 0.67.5
