The OpenFileTable objects are safe to delete while the MDS is offline anyways, the RADOS object names are mds*_openfiles*
I should clarify this a little bit: you shouldn't touch the CephFS internal state or data structures unless you know *exactly* what you are doing. However, it is pretty safe to delete these files in general, running a scrub afterwards is a good idea anyways. But only do this after reading up on lots of details or consulting an expert. My assessment here is purely an educated guess based on the error and can be wrong or counter-productive. All of my mailing list advice is just things that I know off the top of my head with no further research. Take with a grain of salt. Don't touch stuff that you don't understand if you have important data in there. Paul -- Paul Emmerich Looking for help with your Ceph cluster?

Hi Ashley,
Thanks for your response. Nothing that I can think of would have happened. We are using max_mds =1. We do have 4 so used to have 3 standby. Within minutes they all crash.

Quickly checking the code that calls that assert

}
Im not a dev, but not sure if this will help, seems could mean that MDS thinks its behind on omaps/too far ahead.
Anything happened recently? Just running a single MDS?
Hopefully someone else may see this and shine some light on what could be causing it.

Hello,
Hoping you can help me.
Ceph had been largely problem free for us for the better part of a
year.
We have a high file count in a single CephFS filesystem, and are seeing this error in the logs:
/home/jenkins-build/build/workspace/ceph-build/ARCH/x86_64/AVAILABLE_ARCH/x86_64/AVAILABLE_DIST/centos7/DIST/centos7/MACHINE_SIZE/gigantic/release/14.2.9/rpm/el7/BUILD/ceph-14.2.9/src/mds/OpenFileTable.cc:
777: FAILED ceph_assert(omap_num_objs == num_objs)
The issued seemed to occur this morning, and restarting the MDS as well as rebooting the servers doesn't correct the problem.
Not really sure where to look next as the MDS daemons crash.
Appreciate any help you can provide
