SMB ACL Corruption
Description SMB ACLs are corrupt.
Cause
ACLs were accidentally changed by a user or script.
ACLs are corrupted after an anti-virus application accidentally quarantined corresponding files.
ACLs got corrupted after data recovery by a backup application due to compatibility issues.
ACLs got corrupted after migrating data from a different location by using a third-party
application, for example, RoboCopy.
Workaround Check the current ACL setting in the Windows client. Redefine the ACLs for the files by using a
Windows client the same way you initially defined it. Verify that you set the ACLs as the owner of
the files, directories, and SMB shares. If you cannot redefine your ACLs because you currently do not
have permissions, perform the following steps:
1. Restore the files from snapshots or a backup.
2. If you have migrated the data from a different location, for example, using the RoboCopy
application, there is a good chance you can restore ACLs by copying only ACLs metadata, instead
of re-copying the whole data.
3. If all file system ACLs are corrupted you can restore all data from a NAS replication partner.
SMB Client Clock Skew
Description
SMB client clock skew errors.
Cause The client clock must be within 5 minutes of the Active Directory clock.
Workaround Configure the client to clock-synch with the Active Directory server (as an NTP server) to avoid
clock skews errors.
SMB Client Disconnect on File Read
Description
The SMB client is disconnected on file read.
Cause Extreme SMB workload during NAS controller failover.
Workaround The client needs to reconnect and open the file again.
SMB Client Incorrect Password Login Failure
Description
An SMB client fails to log in.
Cause The client supplied the wrong password upon connection.
Workaround 1. Interactive clients can retry with the correct password.
2. Applications and servers might need special attention as the user/password, which is usually set
in a script or configuration file, has probably expired.
