Fixed In Version: ceph-17.2.6-11.el9cp
Doc Type: Bug Fix
Doc Text:
.Client requests no longer bounce indefinitely between MDS and clients Previously, there was a mismatch between the Ceph protocols for client requests between CephFS client and MDS. Due to this, the corresponding information would be truncated or lost when communicating between CephFS clients and MDS, and the client requests would indefinitely bounce between MDS and clients. With this fix, the type of the corresponding members in the protocol for the client requests is corrected by making them the same type and the new code is made to be compatible with the old Cephs. The client request does not bounce between MDS and clients indefinitely, and stops after being well retried.

Description Xiubo Li 2023-02-23 06:07:02 UTC 
Description of problem:

The num_fwd in MClientRequestForward is int32_t, while the num_fwd
in ceph_mds_request_head is __u8. This is buggy when the num_fwd
is larger than 256 it will always be truncate to 0 again. But the
client couldn't recoginize this.
