| |
if frag.mds != cap->session->s_mds, the client's req will be resent.
e.g.
file: mnt/cephfs/dir03/dir003 (0x10000000003) ceph.dir.pin="1"
echo 'aaa' > /mnt/cephfs/dir03/dir003/file29
kernel: ceph: __choose_mds 00000000ca362c7a is_hash=1 (0x7c768b89) mode 2 kernel: ceph: __choose_mds 00000000ca362c7a 10000000003.fffffffffffffffe frag 0 mds1 (auth) kernel: ceph: __choose_mds 00000000ca362c7a 10000000003.fffffffffffffffe mds0 (auth cap 00000000679c38e2) kernel: ceph: __choose_mds using resend_mds mds1
