Subject Replicating, should number of docs be equal in both source/destination db's?
Date Thu, 17 Feb 2011 02:56:19 GMT
I've replicated a database from v1.0.1 to v1.0.2 and below are the
stats I get back when accessing these databases
(http://localhost:5901/stackpdfa_quotes &
http://localhost:5902/stackpdfa_quotes)

v1.0.2 {
   "db_name": "stackpdfa_quotes",
   "doc_count": 32888,
   "doc_del_count": 16,
   "update_seq": 32904,
   "purge_seq": 0,
   "compact_running": false,
   "disk_size": 219832420,
   "instance_start_time": "1297910393331518",
   "disk_format_version": 5,
   "committed_update_seq": 32904
}

v1.0.1 {
   "db_name": "stackpdfa_quotes",
   "doc_count": 33987,
   "doc_del_count": 17,
   "update_seq": 34117,
   "purge_seq": 0,
   "compact_running": false,
   "disk_size": 229212260,
   "instance_start_time": "1297908863487064",
   "disk_format_version": 5,
   "committed_update_seq": 34117
}

While replicating to 1.0.2 couchdb crashed twice with only
"Segmentation fault" in the log. after the 2nd seg fault i compacted
the db on the source node, v1.0.1, and then replicated again and the
replicator says all good...

My question is what has happened to the 699 additional documents that
v1.0.1 reports to have, that v1.0.2 says don't exist??

Here is what the replicator says on v1.0.2 when I pull replicate

[
   {
       "session_id": "f22fbdfc3a69b30664530f4e01e4d2aa",
       "start_time": "Thu, 17 Feb 2011 02:43:37 GMT",
       "end_time": "Thu, 17 Feb 2011 02:44:41 GMT",
       "start_last_seq": 19882,
       "end_last_seq": 34117,
       "recorded_seq": 34117,
       "missing_checked": 0,
       "missing_found": 13020,
       "docs_read": 13020,
       "docs_written": 13020,
       "doc_write_failures": 0
   },
   {
       "session_id": "30dfa60cdc2280eb5414df303629ad34",
       "start_time": "Thu, 17 Feb 2011 02:38:27 GMT",
       "end_time": "Thu, 17 Feb 2011 02:38:41 GMT",
       "start_last_seq": 19175,
       "end_last_seq": 19882,
       "recorded_seq": 19882,
       "missing_checked": 0,
       "missing_found": 6853,
       "docs_read": 2909,
       "docs_written": 709,
       "doc_write_failures": 0
   },
   {
       "session_id": "35135bb220243418e65c27f5f90b3b29",
       "start_time": "Thu, 17 Feb 2011 02:30:46 GMT",
       "end_time": "Thu, 17 Feb 2011 02:32:14 GMT",
       "start_last_seq": 0,
       "end_last_seq": 19175,
       "recorded_seq": 19175,
       "missing_checked": 0,
       "missing_found": 24071,
       "docs_read": 21375,
       "docs_written": 19175,
       "doc_write_failures": 0
   }
]

which according that says everything is ok, still curious why the
databases don't have the same amount of documents...

Thanks,

Nicholas
