NFS mounting options rsize and wsize can't be specified in /etc/fstab

Question

The options rsize and wsize can not be specified on Centos7(3.10.0-123.el7.x86_64)

cat /etc/fstab:

192.168.11.1:/linux_nfs_share /mnt/nfs01 nfs intr,rw,bg,hard,vers=3,proto=tcp,timeo=600,rsize=1048576,wsize=1048576

mount:

192.168.11.1:/linux_nfs_share on /mnt/nfs01 type nfs (rw,relatime,vers=3,rsize=65536,wsize=65536,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys......)

On RHEL6 (2.6.32-358.6.1.el6.x86_64) it works...

mount:

192.168.11.1:/linux_nfs_share on /mnt/FAS_NFS type nfs (rw,bg,hard,vers=3,proto=tcp,timeo=600,rsize=1048576,wsize=1048576....)

Any idea?

Answer 1

Known bug in nfs-utils-1.3.0-0.48.el7_4.2.x86_64 and possibly other versions.

In the current version for CentOS 7.x, nfs-utils-1.3.0-0.61.el7.x86_64, this seems to be fixed.
