Cannot Modify NAS Files
Mixed File Ownership Denied
Problematic SMB Access From a Linux Client
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:
a
Verify there is enough free space on the NAS volume or expand it.
b
Verify that the accessed NAS volume is not a target of a replication.
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.
