In our system test setups with NFSv4.1 mounts, we keep hitting this RHEL client bug where under some unknown condition client fails to send RECLAIM_COMPLETE_OP after client id expiry and recovery. And ganesha keeps sending NFS4ERR_GRACE indefinitely and this client will hit timeout on all the OPENs and hence halting the system testing. We upgraded to RHEL7.7 but still issue persists. I tried searching in redhat bugs but do not see any outstanding issues about this. Is anyone else here facing this issue? Do we know if this is really a RHEL client issue? <ganesha.log> 2020-04-18T16:28:00Z : epoch 5e983c8e : w1hs3e1512.vsanstfsad.local : ganesha.nfsd-164[::ffff:172.30.63.199] [svc_495] 1223 :nfs4_op_open :STATE :Entering NFS v4 OPEN handler ----------------------------- 2020-04-18T16:28:00Z : epoch 5e983c8e : w1hs3e1512.vsanstfsad.local : ganesha.nfsd-164[::ffff:172.30.63.199] [svc_495] 1283 :nfs4_op_open :STATE :OPEN Client id = 5e983c8e00000026 2020-04-18T16:28:00Z : epoch 5e983c8e : w1hs3e1512.vsanstfsad.local : ganesha.nfsd-164[::ffff:172.30.63.199] [svc_495] 507 :create_nfs4_owner :STATE :Previously known owner {STATE_OPEN_OWNER_NFSV4 0x7fe1475ff610: clientid={0x7fe177711ab0 ClientID={Epoch=0x5e983c8e Counter=0x00000026} CONFIRMED Client={0x7fe1777119e0 name=(45:Linux NFSv4.1 w1h34v25-c0017.vsanstfsad.local) refcount=1} t_delta=0 reservations=2 refcount=4} owner=(24:0x6f70656e2069643a0000002c00000000000000c4d78a2b49) confirmed=1 seqid=0 refcount=2} is being reused 2020-04-18T16:28:00Z : epoch 5e983c8e : w1hs3e1512.vsanstfsad.local : ganesha.nfsd-164[::ffff:172.30.63.199] [svc_495] 1322 :nfs4_op_open :NFS4 :open4_validate_claim failed 2020-04-18T16:28:00Z : epoch 5e983c8e : w1hs3e1512.vsanstfsad.local : ganesha.nfsd-164[::ffff:172.30.63.199] [svc_495] 1409 :nfs4_op_open :STATE :failed with status NFS4ERR_GRACE 2020-04-18T16:28:00Z : epoch 5e983c8e : w1hs3e1512.vsanstfsad.local : ganesha.nfsd-164[::ffff:172.30.63.199] [svc_495] 983 :nfs4_Compound :NFS4 :Status of OP_OPEN in position 2 = NFS4ERR_GRACE, op response size is 4 total response size is 92 2020-04-18T16:28:00Z : epoch 5e983c8e : w1hs3e1512.vsanstfsad.local : ganesha.nfsd-164[::ffff:172.30.63.199] [svc_495] 1112 :nfs4_Compound :NFS4 :End status = NFS4ERR_GRACE lastindex = 2 <ganesha.log> We had discussed this before in this community and ganesha behaves as per RFC, so we dint do anything: https://lists.nfs-ganesha.org/archives/list/devel@lists.nfs-ganesha.org/mess...
