Isilon issue or Linux issue?

Mounting the CIFS share with cifs/acl and edit (just edit) the file in Linux, it changes the file permissions.


I think the permissions, are all maintained on the server, which is the Isilon in this case.


Appreciate any help on this

Re: Isilon issue or Linux issue?

I'd guess your Linux editor saves to a new file, aware only of UNIX permission bits,

and on success it deletes the original file and then renames the new one.

It thereby looses the ACL of the original file...

You can check wether a new file is created by tracking file's identity:

On the Isilon, check the LIN with

isi get filename

On the Linux client, check what is reported as "inode" number with

ls -i filename

In the unexpected case that the file's identity does NOT change

let us know; there might be some solution by configuring the Isilon

to ignore UNIX chmod on ACLs.

Re: Isilon issue or Linux issue?

Hi HEagle18,

To start, you could check the settings on the ACL page in the WebUI. I am not sure what version of OneFS you are using to provide direction to that page. There are Admin Guides for each version of OneFS that would prove useful in navigating to and around it though. There is a setting there in which you can allow Dirs/Files with ACLs to be blown away or preserved.

If that doesn't help, I would recommend opening a case with Isilon Support so that they can gather the necessary details to assist in answering your question more thoroughly.

Re: Isilon issue or Linux issue?

sjones, Thanks for your inputs. We use ONEFS 7.2.05, so if a Cifsacl mount is not able to preserve permission at Linux side, then we can tweak this parameters on Isilon Onefs side (according to the version). That is good thing especially when migrating from Netapp to Isilon right?

Was this ever resolved?  I have a customer experiencing this exact symptom.
