Unable to edit files in /vol0 mounted as NFS

Hi,

Banging my head against a wall here;

DOT 8.1.1

vol0 exported and my host added to exports file. qtree for volt set to unix.

#Auto-generated by setup Fri Aug 16 13:26:59 GMT 2013

/vol/vol0 -sec=sys,ro,root=192.168.178.34:192.168.178.201,nosuid

/vol/vol0/home -sec=sys,rw,root=192.168.178.201,nosuid

Unable to edit files in etc even when mounted.

ls -l

drwxr-xr-x 30 20041 _keytabusers 4096 20 Nov 18:06 etc

drwxrwxrwt 3 root wheel 4096 16 Aug 14:26 home

drwxr-xr-x 3 root wheel 4096 16 Aug 14:27 sim

It should be as simple as add device IP to exports. Ensure volt has been set with device IP and given root access.

I cannot get any access, am I missing something.

What is security style of vol0? “qtree status” shows it.

Please follow below Rules while exporting.

Rules for exporting Resources

• Specify complete pathname, must begin with /vol prefix

• Cannot export /vol, which is not a pathname to a file, directory or volume

◦ Export each volume separately

• When export a resource to multiple targets, separate the target names with a

colon (:)

• Resolve hostnames using DNS, NIS or /etc/hosts per order in /etc/

nssswitch.conf

vol0 is unix by default and that is what it is.

qtree is unix

mount command was

mount 192.168.178.200:/vol/vol0 mnt

I can mount it all ok. browse and list. But I cannot write. even though the hosts IP is set as root in exports.

just do the showmount -e <filer Name>; you will see the permissions you have for that linux box.

thank you,

Your export line shows ro - read-only. Change it to rw or rw=<ip addresses>.

Run the following commands:

rdfile /etc/exports

just edit your /etc/exports file to

/vol/vol0 -sec=sys,ro,root=192.168.178.34:192.168.178.201,rw=192.168.178.34:192.168.178.201:192.168.178.200,nosuid

/vol/vol0/home -sec=sys,rw,root=192.168.178.201,nosuid

ctrl -c

exportfs -a

thank you

/vol/vol0/home -sec=sys,rw,root=192.168.178.201,nosuid

your vol0 is exported as ro (read-only) change to rw=<host_name_or_ip-address>. you can check with the persmission with the command exportfs -c ip_address path
