6.3.2 HP StoreAll OS Release Notes

If you do not perform these steps, some Robocopy operations will fail. Specifically, copies of all
read-only files and, in some cases, zero size files, will transition prematurely to a WORM state
during the copy process and Robocopy will be unable to apply all of the source file's attributes
to complete the copies.
Detailed steps are:
1. On every StoreAll cluster node, execute the following commands:
[root@ibrix01b ~]# /opt/likewise/bin/lwregshell
\> cd [HKEY_THIS_MACHINE\Services\lwio\Parameters\Drivers\ibfs]
HKEY_THIS_MACHINE\Services\lwio\Parameters\Drivers\ibfs> add_value
AllowPVFSFilemodeChange reg_dword 0
HKEY_THIS_MACHINE\Services\lwio\Parameters\Drivers\ibfs>exit
2. On the node running the Active Fusion Manager, run the following command to restart
HP-SMB:
[root@ibrix01b ~]# ibrix_server -s -t cifs -c restart
Command succeeded!
3. To disable autocommit, you must unmount the filesystem, modify the Data Retention settings,
and mount it again. See "Changing the retention profile for a file system" in the HP StoreAll
Storage File System User Guidefor more information.
If required, you can re-enable the registry setting after the migration. Run the same commands
as for disabling the registry setting, but change the value of AllowPVFSFilemodeChange
to 1. You can also renable autocommit after the migration, if required.
• The HP SMB authentication process could crash while processing authentication requests that try
to enumerate local users. This problem occurs only when local authentication mode is used and
the local user database has a group that has more than 1,500 users.
• SMB and StoreAll Windows clients cannot be used together because of incompatible AD user to
UID mapping. You can use either SMB or StoreAll Windows clients, but not both at the same time
on the cluster.
• The StoreAll SMB server does not support connections from Linux SMB clients. The workaround
is to use NFS for Linux.
• SMB DCN is supported on Windows File Explorer with the following exception:
◦ The recursive notification flag in the notify request is ignored. Notifications are delivered only
for one directory level.
• When the Microsoft Windows Share Management interface is used to add a SMB share, the
share path must include the StoreAll file system name. The Browse button on the MMC cannot be
used to locate the file system. Instead, enter the entire path, such as C:\data\.
• The StoreAll management console GUI and CLI allow only 9000 file systems and directories to
be exported as SMB shares. However, the Microsoft Windows Share Management interface
allows you to create an SMB share that is not on a StoreAll file system. Although the share will
be available from the file serving node to which Windows Share Management was connected,
it will not be propagated to the other file serving nodes in the cluster.
• The ibrix_localusers -i <user information> command fails if the user information
includes commas. To enter commas in the user information, use the management console GUI
instead of the CLI.
• When you use the Windows security tab to add local users or groups to a security ACL on an
SMB file (for either file or share-level permissions), you typically specify the user to add as either
a DOMAIN\username or a MACHINE\username. On StoreAll systems, local users are displayed
as LOCAL\username, and it may seem like you should specify LOCAL\username in the Add
