cant able to change permission in a DIR as root user

Hi

my directory not accepting any commands. its simply telling permission denied. i tried ( cp, mv, rm ) as roor

i want to set default permissons to this DIR

please find the Logs below.

dr-xr-xr-x 1 root root 1 Jun 1 09:04 AP1_ROP ( original dir)

root> chmod 777 valve
chmod: WARNING: can't change valve

root> getfacl AP2_ROP
# file: AP2_ROP
# owner: bin
# group: bin
user::rwx
group::r-x #effective:r-x
mask:r-x
other:r-x

please give me a solution,

i tried all commands with root login, something went wrong with the directory, its not accepting any commands.

Thanks

Your directory might me remote (eg: NFS) or on a filesystem mounted read-only (eg: lofs mounted shared directory on a zone).

In the first case, switch to the bin user which owns the directory ans isn't subject to root downgrade to nobody.
In the latter case, you need to have the filesystem remounted read-write if this is possible.

why:

chmod 777 valve

?
and not

chmod 777 AP1_ROP

?

sorry duke,

The issue is same, file i mistyped as valve.
filename is AP1_ROP

Thanks

chmod a+rwx filename
chmod -h 666 filename
you have set the any acls telme

Hmm, root is neither constrained by file permissions nor by ACLs.

The filesystem is either mounted read-only or is remote.
