Handle unfound objects in v0.39

2012-06-12 Thread Henry C Chang
Hi, We have some unfound objects in the cluster of ceph v0.39. While recent ceph versions provide the command to mark unfound objects lost, is there any manual procedure to handle unfound objects in v0.39? Assume I know the pgid and oid of the unfound object. I am wondering if the following
