[SOLVED] File/Dir permissions

DBabo · 07-31-2016, 12:30 PM

This is a bit silly.
i have NFS mounted directory and i can not remove a certain directory there even as a root (local).
Local machine is "toshiba"

Code:

[root@toshiba ~]# id
uid=0(root) gid=0(root) groups=0(root)
[root@toshiba ~]# 
[root@toshiba ~]# 
[root@toshiba ~]# cd /home/az/Server_Videos/Movies/Hollywood/
[root@toshiba Hollywood]# ls -l ./Pirates\ of\ the\ Caribbean\ -\ Curse\ of\ the\ Black\ Pearl\ \(2003\)\ \[1080p\]
total 4288

Well I just hope that none of the members here work for the MPAA or your country's equivalent thereof.

What are your mount options? Were you previously able to have write access to the disk and suddenly it doesn't work, or has it never worked as far as you know? Which of the two linux systems mentioned in your profile are you using?

Emerson · 07-31-2016, 12:59 PM

root is local account and has no business poking on remote shares, by default root has no rights on those shares.

chrism01 · 08-02-2016, 02:51 AM

yeah, nfs servers would normally set the root_squash option

Sorry about not providing the requested details - had a perfect storm of sorts.

i have other directories that i can remove/add, but this one. i'm not sure since when this ( inability to modify) started.
on the client (fedora 22 ) mount options are :

Code:

nfsvers=4,_netdev,defaults,bg,user,auto,noatime,intr 0 0

on the server /etc/exports:

Code:

/mnt/storage/Video 192.168.1.201(rw,async,all_squash) 192.168.1.112(rw,async,all_squash) 192.168.1.104(rw,async,all_squash)

where "toshiba" has an 201 ip.

oh.... i should have not been doing anything after 22:00 - old man should rest.
why in the universe would i use client's "root" account against nfs mount?? - go sleep oldy.

Sorry about wasting space and your time. @Emerson - thank you for making me look at my posted log.
