NAS folder read only?

T-K-O

Hi guys,

I have a netgear NAS drive that I use to store all media. Every so often when copying files from the iMac to the NAS it will say that the particular folder is now read only.

Logging in as admin makes no difference and I have limited options on the permissions.

I get around this by creating a new folder but as you can imagine that's a pain.

Any advice?

i've had awful trouble recently with my NAS drive & Mountain Lion in Finder. I now use CyberDuck, it's free and works a lot better. Quicker to create/edit folder & file names. Files also transfer quicker

I have cybderduck, never thought to use it. Thanks for that.

Make sure the NAS drive is formatted as FAT32 not NTFS...Mac can only read but not write to NTFS.

Thanks for the reply.

I assume the drive is FAT32. The NAS is installed since Xmas. This rights issue happens out of the blue on certain folders.

99% of the time read / write works just fine.

Hmm if its only certain folders, check out the permissions ....
right click on the folder -> Get info and check out the permissions for that folder, make sure your user account has both read / write privileges, if not adjust and click on the gear to apply to enclosed items.

When the folder decides to become read only (after working perfectly before) I cannot access the permissions, well, I can click permissions but there are no options.

The only solution to date is to create a new folder and copy my data from the locked folder to the new folder- It's a pain

Just to make sure that the padlock isn't locked and its your username with read/write permissions ..

Please see my attachment as a reference.

NAS units are normally formatted with Linux and you won't see the Mac permissions as you show. Normally you have to access the permissions through the NAS software itself.

You mean ext3? I doubt it..

Do you mean the NAS unit may be running a Linux based OS?

Any NAS unit I've seen is running Linux.

They may be running on linux OS but they are not "formatted" as Linux - Nevermind, Helps to phrase things better..

Also, not true, A NAS unit can simply be a rack of hard drives on an ethernet card so to speak... not running linux.

Anyhow this doesn't help the OPs issue....

OP - Is the NAS unit Linux based - Whats the make/model of your NAS drive

Apparently RAIDiator (the firmware on the ReadyNAS) is based on Debian Linux.

I'm not sure how you would implement a NAS without ANY OS however this is not an issue for the OP. The OS on the NAS box is agnostic of the filesystem on the storage.

The problem is more likely due to the differences regarding permissions on HFS+ filesystem versus FAT32 filesystem.

MAC OSX doesn't generally have any issues with FAT32 - Interesting point though.

Since it is linux based, there may be an option to repair permissions on the NAS drive similar to disk util on the mac...

Hey guys


The NAS is a NETGEAR ReadyNAS Duo 2-Bay , not sure if the O/S is a linux based. I cannot replicate the issue right now but I can tell you guys when the folder is locked, I cannot access any permissions for that locked folder.

I also have a windows 7 laptop. I wonder if that is causing the problem but I rarely access the NAS form the laptop

OK I lied, the OS on the NAS box is not agnostic of the filesystem on the storage. The RAIDiator firmware that runs on the ReadyNAS series has 3 different varieties, ARM, X86 and SPARC. Check which exact model you have because you need SPARC firmware for Duo V1 and ARM firmware for Duo V2. I mention this only to allow you to confirm that you have the latest firmware on your box.

Does this problem only occur with one type/ size of file?

from having this issue myself im certain in saying its nothing to do with the NAS/firmware etc so no need to go into all this nitty gritty detail on which firmware is on the nas... it's a problem that happens with mac osx - there is a new update out 10.8.4 that address issues with network drives so this may sort it out

There is nothing in the fixes in 10.8.4 update to solve the OP's problem ( no harm in applying it nonetheless ).

What has convinced you that it is not firmware related or repairable with firmware upgrade?

I am also interested to find out if the problem relates to particular filetypes or sizes.

would this not help with network drives?
"A fix for an issue that may prevent documents from being saved to a server using SMB"

I don't think it's the unit becuase i have different brands of NAS at home and I am having the same issues

The problems I had with my NAS was on any file size - 5mb MP3, 7GB MKVs - seemed to be on anything

And the fact that when I used CyberDuck (or another FTP type program) there were no issues lead to me belive it was Mac OSX - there have been loads of issues with Mountain Lion and network shares

Hey guys,

I use the NAS for media storage. So, this has happened with various audio and video formats. Size, anything from 4 mb to 1gb.

Since I created this thread the issue has not resurfaced. I have also updated the firmware on the NAS. Arm 5.3.8

Ill keep you guy posted

Could this be a extended file attributes problem and if so the xattr command may help (look for the '@' symbol).

Mention of SMB got me thinking and I discovered this article. I am not sure if this KnowledgeBase article (fix under Disabling named streams) is relevant.

It might be worth your while to disable the Mac extended file attributes. The process of FTP may be doing this hence the problem goes away when using this option.
