Hi,
I am facing a problem where-in some files are not visible across NFS and
hence, not able to read those files. However, after sometime, the files
become visible and the data is accessible. I have tried to do an 'ls -l'
operation on the directory and repeat it till the directory gets mounted
and visible. This works in some cases but sometimes fails as well.
Is there any reliable way of ensuring that the directory gets mounted
and all files in it are visible before accessing the data ??
Any help/pointers in this regard would be really great.
Hi,
Many Ubuntu users seem to be experiencing such problems on ubuntu-2.6.17
kernels:
https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.17/+bug/62308
In my experience, everything works fine as long as all
directory-elements in
the path on the nfs mount are set executable for user _and_others_. If
that
is not the case, files are available for about five seconds after the
first
access, after which they disappear. If I try to access the file again I
get
a "permission denied" message. No messages get logged.
For me, adding the "no_subtree_check" option in /etc/exports 'fixed' the
problem. I'm on ubuntu-2.6.17-11-generic on amd64. This works for me:
/home
192.168.22.0/255.255.255.0(rw,sync,no_subtree_check,mp=/home,fsid=12120)
/scratch
192.168.22.0/255.255.255.0(rw,sync,no_subtree_check,mp=/scratch,fsid=12121)
Anyhow, you did not give any information about your
distro/kernel/hardware?
Greetings,
Alexander
