Cannot Modify NAS Files

Description

A user or an application cannot modify a file.

Cause

• The client cannot modify a file due to lack of permissions on the file.

 

• The NAS volume has reached full capacity and the file system

 

denies any write requests, including overwrites.

 

• The NAS volume is a target in a replication relationship and is

 

read only.

Workaround

1 If the problem appears only on some files, this is a permission

 

issue. Verify that the user account has modify permissions on the

 

file or use a different user account.

 

2 If the problem is related to a specific NAS volume:

aVerify there is enough free space on the NAS volume or expand it.

bVerify that the accessed NAS volume is not a target of a replication.

Mixed File Ownership Denied

Description

Both file owner and group owner must be from the same identity

 

type (UNIX vs NTFS). An attempt to set different identity types

 

was detected.

Cause

It is impossible to change only the file owner id to UID if the

 

original file ownership is SID/GSID.

Workaround

To change the file ownership to UNIX style ownership, set UID

 

and GID at same time.
