I have an NFS cliet that is mounting a filesystem. We have been given requirements that the filesystem is to be mounted with the noac option and the nointr option.

I have placed these options in /etc/fstab. The system was booted and mounted. The contents of /etc/mtab included noac and nointr. However, these two options do not appear in /proc/mounts.

Our Oracle consultants are insisting that these two options should appear in /proc/mounts, and really aren't progressing through a specific problem we're having; they're getting hung up on this. Until these options appear in /proc/mounts, I don't think we're getting any more help.

I tried mounting specifically with the mount -o remount,nointr,noac - but still the options do not show in /proc/mounts. (Again, they DO show in /etc/mtab)

Here's the specific entry you DO see in /proc/mounts:

somehost:/oraspace-2 /oraspace-2 nfs rw,vers=3,rsize=32768,wsize=32768,hard,proto=tcp,timeo=600,retrans=2,sec=sys,addr=chloraprod1 0 0

This is a RHEL 5.3 box. Output of uname -a:

Linux CHLORAPROD2.internal.realtors.org 2.6.18-128.1.14.el5 #1 SMP Mon Jun 1 15:52:58 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux

Any ideas?

You're right -- they don't show in /proc/mounts. I couldn't say for sure, but it seems that this patch: http://www.mail-archive.com/git-comm.../msg25412.html is not included in RHEL 5.3. See http://www.mail-archive.com/linux-fs.../msg11375.html for a rationale on why this is done. /etc/mtab should be correct.
