Now that we have open file cache, it is possible that another client deletes the file and DP will not know about it. Then IO to MDS would fail with BADSTATEID and knfsd would start state recovery, which should fail as well and then nfs read/write will fail with EBADF. And it triggers a WARN() in nfserrno(). -----------[ cut here ]------------ WARNING: CPU: 0 PID: 13529 at fs/nfsd/nfsproc.c:758 nfserrno+0x58/0x70 [nfsd]() nfsd: non-standard errno: -9 modules linked in: nfsv3 nfs_layout_flexfiles rpcsec_gss_krb5 nfsv4 dns_resolver nfs fscache ip6t_rpfilter ip6t_REJECT nf_reject_ipv6 xt_connt pata_acpi floppy CPU: 0 PID: 13529 Comm: nfsd Tainted: G W 4.1.5-00307-g6e6579b #7 Hardware name: VMware, Inc.
