I use external tools to examine logs like cconsole.log though. 1 0 https://community.intersystems.com/post/notification-mirror-failure#comment-235996 go to post Alexander Pettitt · Sep 11 Was so happy to discover d ConvertShadowDatabases^MIRROR 0 0 https://community.intersystems.com/post/video-stepping-out-shadows-how-us-va-migrated-mirroring-intersystems-iris-cloud#comment-235936 go to post Alexander Pettitt · Sep 10 First my experience is on IRIS.DATs that were 2Tb is size and experience will vary widely since where the free space is is what matters. There are two different compacts:Compact globals in a databaseCompact free space in a databaseIf all you want to do is compact free space things are easier.Do it in small steps with ^DATABASECurrent Size: 2307950 MBTotal freespace: 8564 MBFreespace at end of file: 18 MB Target freespace at end of file, in MB (18-8564):200 One great feature is you can cancel if you need to.Press 'Q' to return, 'P' to pause, 'C' to cancel: Truncation can be done in the same way in steps. If you have one I suggest that you do this on your DR instance, move to DR and then do it on what was production. If you are using 8k blocks for IRIS you should start thinking about the 32Tb limit for 8k databases.You need to run an integrity check after you are done. If you wanted to run compact globals that is much more complex. If the underlying storage does deduplication you should make sure you have extra space at that layer. 0 0 https://community.intersystems.com/post/compacting-and-truncating-very-large-datasets#comment-235766 Followers:Alexander has no followers yet.Following:Alexander has not followed anybody yet.Global Masters badges:Alexander has no Global Masters badges yet.
