I was finally able to get the ML 4.2 backup to restore on ML 7.0 by changing the database journaling setting to off. Once rebalancing is complete, I will change the journaling setting to strict as recommended for shared disk failover.

Is it just that forest that is having trouble mounting? How big is this backup (size and number of forests)? Are you restoring into the exact same topology as you backed up from (that is what restore expects)? -Danny From: Gene Thomas [mailto:[email protected]] Sent: Friday, March 28, 2014 2:16 PM To: Danny Sokolsky; MarkLogic Developer Discussion Subject: Re: [MarkLogic Dev General] ML 4.2 backup restore to ML 7.x Thank you Danny, That is what I am trying to do. Here is the text of an email I sent internally about it. We have an NAS mount connected to both clusters. On the ML 4.2 side it is read/write. On the ML 7.x side it is mounted read only. I have not been able to complete a restore from that location either by database restore or forest restore. The access to the /Marklogic_temp/ mount may need to be read write. When the actual restore process gets to 00:00:00 estimated time left, it just sits there with the forest state saying “recovering” I see this message in the logs at that point: Mar 28 16:01:02 MarkLogic: Missing journal file /mldata02/RestoredForests/dodge-daily-forest01/Journals/Journal1-19700101000000-0-0-0 I have waited 30 minutes past the time it said it had finished copying data and still no completion of the restore. Any help would be appreciated as we are supposed to perform the actual process from ML 4.2 QA to ML 7.x QA over the weekend.

I would expect that, as soon as it mounted the db in 7, that it would start reindexing (if reindexing is enabled). I would test it first, but I think it will work. -Danny From: [email protected] [mailto:[email protected]] On Behalf Of Gene Thomas Sent: Friday, March 28, 2014 1:59 PM To: [email protected] Subject: [MarkLogic Dev General] ML 4.2 backup restore to ML 7.x Has anyone successfully backed up a database on ML 4.2-7 and restored it in a new environment with a fresh ML 7.0-2.1 install?
