Description

Seen on mira021 long-running MDS.

(where j is the damage json)
>>> [d for d in j if d['ino'] == 1099529116670]
[{u'frag': u'*', u'ino': 1099529116670, u'damage_type': u'dir_frag', u'id': 197657288},
 {u'frag': u'*', u'ino': 1099529116670, u'damage_type': u'dir_frag', u'id': 244045365}]

The inserting logic should be checking for existing entry of same inode+type before inserting, but apparently it's not. There are only 670 unique inodes mentioned, but there are 1352 entries in the damage table.
