6.0.2 HP IBRIX X9000 Storage Release Notes (AW549-96044, January 2013)

• When a snapshot was taken, files could be deleted from the source directory.
• CIFS shares were inaccessible, and the Windows client accessing the filesystem using CIFS would
be shown the message: The specified server cannot perform the requested
operation. The cause was an SMB 2.0 credit exhaustion issue that was seen on applying a
specific load pattern for a prolonged period of time on an HP-SMB server. The fix addresses the
credit leak that was a result of corruption in the inherent data structure implementation.
• Stack overflows were occurring, as a result of some of some of the IBRIX commands, such as
ibrix_fs requiring a large buffer. The fix lessened the risk of a stack overflow.
• There were too many clients registering for DCN (Directory Change Notification) and the
notification queue would get overloaded, leading to an ASSERT resulting in a segmentation fault
of the Lwiod daemon. The fix adds proper handling of the overload situation, thereby avoiding
the ASSERT.
• During a mkdir operation, the xdr_encode_netobj dereferencing NULL
xdr_netobj->data pointer message was displayed. The underlying issue has been resolved
so the message no longer appears.
Fixes in the 6.0.1 release (build 6.0.340)
The following fixes were made in this release:
• The correct creation time was not maintained when a file on a CIFS share was modified or moved.
Now, when a file is moved or modified, the original creation time is preserved as a file property
visible to the client.
• It was possible to create two directories with the same name, but differing in case, if one of the
names used characters from the Latin-1 character set. Users were then unable to save or retrieve
files from one of the directories.
• When a CIFS client did not close a file gracefully, the files in the CIFS share were locked.
• When a local user or group was deleted, the user or group was not deleted from the CIFS
database.
• CIFS users in extended ACLs were incorrectly given permissions that should be applied only to
the owner of the file.
• Run-once remote replications did not replicate files correctly when the source or destination
directory name included spaces.
• The defaults for the TcpKeepalive parameters on the CIFS server did not match the defaults on
Windows servers.
• An @ symbol could not be used in a file or directory name.
• When the active management console failed over, ibrix_event did not send the correct email
notifications.
• An lwiod failure caused the CIFS service to stop.
• If a directory name ended with the @ symbol, the contents of the directory could not be read when
it was restored from a snapshot.
• The CIFS server did not handle requests properly when filenames had leading backslashes.
• When attempting to add ACLs on files and folders in a CIFS share, local users were not visible.
You can now add local users; however, the cluster or client should be in the domain.
• NDMP backups failed when used with the VLS 9200.
• An attempt to create a file over RPC succeeded, but the file did not exist.
• When a user quota setting was changed, the ibrix_edquota -l command reported the error
RealQuotaMonitor - directory tree quota has unparsable output.
