I am configuring a Linux Server with ACL[Access Control Lists]. It is not allowing me to perform setfacl operation on one of the directoriy /xfiles. I am able to perform the setfacl on other directories as /tmp /op/applocal/.

I am getting the error as :

root@asifdl01devv # setfacl -m   user:eqtrd:rw-,user:feedmgr:r--,user::---,group::r--,mask:rw-,other:--- /xfiles/change1/testfile
setfacl: /xfiles/change1/testfile: Operation not supported

I have defined my /etc/fstab as

/dev/ROOTVG/rootlv      /                       ext3    defaults        1 1

I have a solaris server where the vfstab is defined as

cat vfstab

I am not able to find out the issue. Any help would be appreciated.
