[. . . ] For asynchronous writes: Although Server for NFS informs the NFS client that the data has been safely written to disk, the data is still stored in cache, and is waiting to be written to disk. This might cause file corruption issues if, for example, you lose your power supply to the Server for NFS server while data is still in the cache. At this point, the NFS client assumes that data that was lost was actually safely written to disk. With synchronous writes on (caching off), all write requests are immediately committed to disk before a response is sent. Although synchronous writes "on" does frequently slow NFS file writes, it does improve the stability and data integrity. 6 HP StorageWorks NAS 1200s Release Notes WARNING: Turn asynchronous writes on only if you are willing to risk file corruption if any issue with the NFS server causes the cache to be lost (for example, if the system shuts down, stops responding, loses its power supply, or experiences other serious issues). Clearing the NFS log via the WebUI causes the log file to become inaccessible When clearing the NFS logs via the WebUI, the log file will clear but the file permissions are set incorrectly. Access to the log c:\msnfs\logs with Windows Explorer will be denied. To resolve the issue, stop the Server for NFS service, clear the NFS log, then start the Server for NFS service. The log file will then be accessible. NFS administrative shares support Services for NFS does not work with administrative shares in the same fashion as CIFS. By default, a volume drive such as C: is CIFS shared as C$. This is an example of an administrative share and is hidden to CIFS clients. If an NFS share is created and named driveS, as in the example, the share will not be hidden to NFS clients. This NFS share will act as a normal NFS share. Volume Mount Points support Attempting to create an NFS share on a disk mounted on a mount point will result in the error: Cannot write IOCTL to NFS driver. . . HP StorageWorks NAS 1200s Release Notes 7 HP StorageWorks NAS 1200s supports many network sharing protocols including the NFS protocol for UNIX® and Linux clients. Shares for which the NFS protocol will be enabled must be created on logical disks that are mounted on a drive letter. Microsoft® Windows® Storage Server 2003 supports mounting virtual disks onto mount points or reparse points created on another disk already mounted on a drive letter. Mount points enable the administrator to mount many disk devices under a single drive letter, creating the appearance and behavior of a larger disk drive with a contiguous namespace. However, the Microsoft Services for NFS Server does not yet support the functionality of mount points. All logical disks to be used for NFS sharing should be mounted on a drive letter, not on a reparse or mount point. If no NFS shares will be created on a particular logical disk, that virtual disk may be mounted on a mount point instead of a drive letter. Admin cannot list and map domain users and groups for NFS mapping unless the NFS admin is logged into the domain The admin must log into the domain before mapping domain users and groups. If the admin is not logged into the domain, the domain user or group is not on the list of Windows users or groups and cannot be mapped. User name mapping Japanese characters User name mapping for the network file system (NFS) server does not support UNIX user names containing Japanese characters. The names of NFS client groups that are used by the NFS server cannot contain Japanese characters. 8 HP StorageWorks NAS 1200s Release Notes Comments in Password and Group file not recognized Comments preceded by a "#" in the Password and Group file will not be recognized when specifying the Password and Group file for setting up the User and Group mappings of the NFS protocol. If a Password or Group file is used with a comment, the following error will be displayed in the WebUI: "The user list cannot be retrieved. Make sure the password file is not corrupted and then try again". Mapping Service Fails to Start If all network ports are not attached to an active link or contain a port terminator, the mapping service will fail to start on boot. [. . . ] The user receives a Not enough free disk space error message when disk space is indeed available, the file is simply blocked. Cannot connect to AppleShare from a MacIntosh machine Using a Mac OS X machine when accessing a NAS share returns an error indicating: No file services are available at the URL afp://IPaddress. Try again later or try a different URL (server returned error-5002. If the client authentication method is set to MS + Appletalk, clear text on the client and the operation will succeed. HP StorageWorks NAS 1200s Release Notes 15 Quick Restore Process The Quick Restore DVD restores the NAS 1200s to its factory default state. CAUTION: The NAS Quick Restore will erase all data on the system drives. Refer to the HP StorageWorks NAS Administration Guide and the HP StorageWorks NAS Installation Guide for information on backing up data prior to performing a Quick Restore procedure. . Supported USB DVD Drives This Quick Restore DVD is intended for DVD drives that have a manually loading tray. If your DVD drive has an automatic tray, ensure that the DVD is removed when it is ejected. [. . . ]
