df: cannot statvfs Permission denied on cluster file system

Question

Hi ,

Does any one got any idea why I am getting the permission denied error when I do the&nbsp;&nbsp; df -k&nbsp; on a 3 node cluster with a shared Cluster file systems (CVM)

I can do the df -k on&nbsp; the master server as a normal user&nbsp; ,however ,I can get the df -k on other two nodes ,

[abcadmin@sol100]: /&gt; sudo vxdctl -c mode
mode: enabled: cluster active - MASTER
master: sol100

[abcadmin@sol100]: /&gt; df -kh

all three servers got same permission&nbsp; for the mount points ...

Really appreciate if any one can show som lights on this , I just wanted this for a monitoring script to run as a normal user than root ..

Thanks in advance ..

That seems to have no relation to CFS or CVM ..... From google it looks to be purely a solaris issue...

Did you had a run through any of these:

The user is contained in a group, does that group have a atleast read access to the filesystem ?

Gaurav,

the permissions are exactly same on all three nodes ,

[abcdmin@sol100]: ~&gt; ls -ld /opt/fwire/Shared
drwxrwxr-x&nbsp; 26 delfw01&nbsp; fwire&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1024 Aug 13 15:25 /opt/fwire/Shared

[abcadmin@sol300]: ~&gt; sudo ls -ld /opt/fwire/Shared
drwxrwxr-x&nbsp; 26 delfw01&nbsp; fwire&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1024 Aug 13 15:25 /opt/fwire/Shared

it has 775 permission on those folders , which should allow all other users to just read though its not part of that group correct ..?

I just forgot to mention the volume permission on this which is set to 770&nbsp;&nbsp; "perms:&nbsp;&nbsp;&nbsp; user=delfw01 group=fwire mode=0770"

but I dont understand why I can read that from the master server&nbsp; ..? and not on other nodes.

Thanks

hmm makes sense that it should allow the read access..... by any chance have you setup solaris auditing ?

Yep&nbsp; ,we got auditing enabled

online&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Apr_23&nbsp;&nbsp; svc:/system/auditd:default

gaurav_s · Answer

looking for it, in the mean time have a look at this:

http://support.bb4.com/archive/200608/msg00024.html

Not able to remember exactly, there was something around auditing which use to cause this.... trying to find right doc for this...
