Hi all, > Caused by disabled CONFIG_NFSD_V[34] in kernel config. Looking for other errno in nfs-utils (in utils/mount/): EACCES 13 Permission denied EAFNOSUPPORT 97 Address family not supported by protocol EAGAIN 11 Resource temporarily unavailable EALREADY 114 Operation already in progress ECONNREFUSED 111 Connection refused EINVAL 22 Invalid argument EIO 5 Input/output error ENOMEM 12 Cannot allocate memory EOPNOTSUPP 95 Operation not supported EPROTONOSUPPORT 93 Protocol not supported ESPIPE 29 Illegal seek ETIMEDOUT 110 Connection timed out I suppose I should add only: EAFNOSUPPORT 97 Address family not supported by protocol (I guess for kernel without IPv6 support). But doing a quick test with v3 enabled and v4 disabled: CONFIG_NFS_V2=m CONFIG_NFS_V3=m # CONFIG_NFS_V3_ACL is not set # CONFIG_NFS_V4 is not set CONFIG_NFSD_V3=y # CONFIG_NFSD_V3_ACL is not set CONFIG_NFSD_V4=y nfs-utils does not print it for enabled protocol: nfs01 1 TINFO: setup NFSv3, socket type tcp6 nfs01 1 TINFO: Mounting NFS: mount -v -t nfs -o proto=tcp6,vers=3 [fd00:1:1:1::2]:/var/tmp/LTP_nfs01.XXXXySFHMF/3/tcp6 /var/tmp/LTP_nfs01.XXXXySFHMF/3/0 mount: mounting [fd00:1:1:1::2]:/var/tmp/LTP_nfs01.XXXXySFHMF/3/tcp6 on /var/tmp/LTP_nfs01.XXXXySFHMF/3/0 failed: Input/output error nfs01 1 TBROK: mount command failed but it does for disabled protocol: nfs01 1 TINFO: setup NFSv4, socket type tcp6 nfs01 1 TINFO: Mounting NFS: mount -v -t nfs -o proto=tcp6,vers=4 [fd00:1:1:1::2]:/var/tmp/LTP_nfs01.XXXXWyckxh/4/tcp6 /var/tmp/LTP_nfs01.XXXXWyckxh/4/0 NFS: NFSv4 is not compiled into kernel mount: mounting [fd00:1:1:1::2]:/var/tmp/LTP_nfs01.XXXXWyckxh/4/tcp6 on /var/tmp/LTP_nfs01.XXXXWyckxh/4/0 failed: Protocol not supported mount: mounting [fd00:1:1:1::2]:/var/tmp/LTP_nfs01.XXXXWyckxh/4/tcp6 on /var/tmp/LTP_nfs01.XXXXWyckxh/4/0 failed: Protocol not supported nfs01 1 TCONF: Protocol not supported It might be a problem with LTP tst_net.sh library, which might not support disabled IPv6 properly.
