Nowadays, I am wondering doing offline deduplication in ceph? My idea is: First in the ceph-client, I try to get the locations of chunks in one file. The information includes how many chunks the file has and which osd the chunk(object group) has been stored. Then the ceph-client try to communicate with the exact osd to ask the osd to return the chunk hash. After that, we compare the returned hash with the already stored hash table, If the chunk is duplicated, we try to change the file meta-data. Can it work? Can you give some ideas? Thank you lollipop -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
