Dear Team, Following is our configuration: tomb-raider-eligible-age=6Hrs We have the following scenario: Case -1: On a Site (having multiple Aerospike DB in acluster) which is In-Service and some db from the cluster are down for more than 6 hours – Its clear that we need to follow → Take down a …

Team, Can you please respond to the above qurey / Thanks in advance ! Regards Asif

[image] asifansari80: tomb-raider-eligible-age On case 1, and independent of XDR, it is the recommended to wipe out the node that was out for a while pass the tomb-raider-eligible-age. Configuration reference | Aerospike Documentation On case 2 which version of XDR? On latest XDR there is no…

Thanks a lot for the feedback !! Not sure if i get the correct version of the XDR, i used the following command to get the following: Admin> summary -l Cluster Server Version : E-4.5.2.6 –To recover the local site and since all nodes were down past 6 hours, you could remove the digestlog on …

4.5 is an older build with Digestlog. I’d recommend trying out the new version 5.x without digestlog. Assuming there was no lag when you shutdown the entire cluster you can remove the digestlog by simply deleting it with rm after having stop that node for the more than 6 hour maintenance. This woul…

Hi, looking at this post can see in case the duration of thr DB down exceeds the tomb-raider-eligible-age it’s mandatory to coldboot/clean the affected node(s). I understand: https://www.aerospike.com/docs/reference/configuration/#tomb-raider-eligible-age proposes this approach, but at the same time…

Thanks a lot for the clear explanation, really appreciated! Mike

Since you have been so kind would like to get more about the Initial Case 2.1 where we have one XDR site going down cleanly, no lag, so basically no information needed on local digestlogs. We keep this one XDR site down for more than configured tombstone eligible age and in the meantime the digestl…

I would expect that tombstones created and subsequently cleared while the remote site was down to not be replicated. The digestlog cannot ship a tombstone that has already been deleted.

Thanks a lot, if digestlogs as well are clearing the tombstones then it makes perfect sense, appreciated Mike
