Here is the debug data when using a ceph-fuse client.
We did reproduce the problem
- Subject changed from lifcephfs/ceph-fuse: unlinked file does not release cap to mds quickly to multimds: unlinked file is not pruned from replica mds caches
- Category set to 47
- Status changed from New to Fix Under Review
- Backport set to firefly,dumpling
looks like the problem is that another mds has the inode in its cache and isn't trimming it (or being asked to trim it) when nlink drops to 0.
- Status changed from Fix Under Review to 12
- Backport deleted (
firefly,dumpling)
- Priority changed from High to Normal
- Category changed from 47 to 90
- Component(FS) Common/Protocol, MDS added
- Category deleted (
90)
- Labels (FS) multimds added
- Status changed from 12 to New
