Hello K, We have found our issue – we were only fixing the main RDB image in our script rather than the snapshots. Working fine now.
Thanks for your help. Kind regards, Glen Baars From: Konstantin Shalygin <k0...@k0ste.ru> Sent: Friday, 17 August 2018 11:20 AM To: ceph-users@lists.ceph.com; Glen Baars <g...@onsitecomputers.com.au> Subject: Re: [ceph-users] Invalid Object map without flags set We are having issues with ensuring that object-map and fast-diff is working correctly. Most of the time when there is an invalid fast-diff map, the flag is set to correctly indicate this. We have a script that checks for this and rebuilds object maps as required. If we don't fix these, snapshot removal and rbd usage commands are too slow. About 10% of the time when we issue an `rbd du` command we get the following situation. warning: fast-diff map is invalid for 2d6b4502-f720-4c00-b4a4-8879e415f283 at 18-D-2018-07-11<http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com>:1109. operation may be slow. When we check the `rbd info` it doesn't have any flags set.
