Fixed In Version: ceph-17.2.3-1.el9cp
Doc Type: Bug Fix
Doc Text:
.A replica MDS is no longer stuck, if a client sends a getattr client request just after it was created Previously, if a client sent a getattr client request just after the replica MDS was created, the client would make a path of `#INODE-NUMBER` because the `CInode` was not linked yet. The replica MDS would keep retrying until the auth MDS flushed the `mdlog` and the `C_MDS_openc_finish` and `link_primary_inode` were called 5 seconds later at most. With this fix, the replica MDS trying to find the `CInode` from auth MDS would manually trigger `mdslog flush`, if it could not find it.
