I. OVERVIEW:
------------
Symantec FileStore provides a scalable clustered storage solution. This document provides release information for the patch.


II. UPGRADE PROCEDURE:
----------------------
After you have installed or synchronized a new Symantec FileStore patch into your cluster, the list of available commands may change. Please login again to the CLI to access the updated features. 

IMPORTANT: There is a downtime for the services during an upgrade. The actual downtime will be a little longer than it takes to reboot the system. To avoid data loss, Symantec recommends that customers stop I/O processing completely during a patch upgrade.  

After you apply this patch, you cannot uninstall it. The 5.6 RP1P4 patch can only be installed on 5.6 or 5.6 P1 or 5.6 P2 or 5.6 P3 or 5.6 RP1 or 5.6 RP1 P1 or 5.6 RP1 P2 or 5.6 RP1 P3.


To install the patch:
1. Login as master:
   su - master
2. Start the patch install:
   upgrade patch install

IMPORTANT: Full upgrade instructions are included in the Symantec FileStore 5.6 Release Notes. Please note the following revisions
When you upgrade:

* Symantec recommends that you remove I/O fencing before upgrading any cluster node or exporting your current configuration. Use the Storage> fencing off command first followed by the Storage> fencing destroy command to remove I/O fencing. This step is not required, but it is suggested for a clean upgrade.

IV. KNOWN ISSUES:
-----------------
Etrack Incident: 2737179

Symptom: 
Manual scan cannot detect the virus file without file extension (e.g. 11) when the ¡°File excluded extension list¡± setting is empty.  

Description:
This issue only happens on manual scan with the ¡°File excluded extension list¡± setting is empty, this issue has been fixed in Auto-Protect scan, then we suggest you enable Auto-Protect to avoid this risk. If you do not want enable Auto-Protect since Auto-Protect scan brings some CPU consumption, you can use the workaround as below.  

Resolution:
The workaround is to keep at least one file extension in the ¡°File excluded extension list¡± setting. you can set one unusual file extension to avoid this issue, for example ¡°dummyextension¡±, in fact, there should not be any file with such file extension

Etrack Incident: 2724702

SYMPTOM: For mapped users with the same user name for both CIFS/NFS shares using "full_acl," you may encounter permissions issues.

DESCRIPTION: If you map users with the same user name using both CIFS and NFS, users using "full_acl" may encounter permissions issues when trying to access directories or files created by NFS users.

RESOLUTION:

The work-around is to set "no_full_acl."

Etrack Incident: 2700195

SYMPTOM:
Missing information about support of Active Directory Japanese user names/groups from the Symantec FileStore documentation.

DESCRIPTION:
Symantec FileStore documentation should include information on support of Active Directory Japanese user names/groups.

RESOLUTION:
Symantec FileStore supports Japanese, Korean, and Chinese local user/group names in areas supported by SAMBA.

Etrack Incident: 2722856

SYMPTOM:
While shutting down a node, unmounting a file system or destroying a file system, it takes a long time to complete the operation.

DESCRIPTION:
While shutting down a node, unmounting a file system or destroying a file system, it takes a long time to complete the operation. This happens if there are any pending snapshot operations on the file system. The unmount operation hangs until the snapshot operation is completed.

RESOLUTION:
Introduced a way to postpone the snapshot operations. This helps to unmount the file system, destroy the file system, or shutdown quickly. Applying this patch helps to get rid of the issue.
 
Etrack Incident: 2632963

SYMPTOM:
Storage> tier relocate command will not relocate all files, and the Storage> tier remove command requires all its policy files to be removed.

DESCRIPTION:
The Storage> tier relocate command skips NDS files. NDS includes named data streams and extended attributes. The Storage> tier remove command is successful only if all the policies related to the tier are removed. The Symantec FileStore man pages have been updated to reflect the same.

RESOLUTION:
There is no resolution for the NDS relocation issue. 
Run the Storage> tier policy remove <fs_name> command before running the Storage> tier remove command.

Etrack Incident: 2738026

SYMPTOM: 
Antivirus Liveupdate jar file symbol link on master node and newly PXE booted nodes points to different versions of jar file.
  
DESCRIPTION:
After upgrade to 5.6RP1P4, rpm of savjlu upgrades to version savjlu-1.0.12-8 on all nodes. But due to difference in savjlu package upgrade on master and  newly PXE booted nodes, it could result in the symbol link of /opt/Symantec/LiveUpdate/jlu.jar points to different jar version (jlu-3.5.1.34.jar or jlu-3.9.1.14.jar).

RESOLUTION:
No need any workaround as antivirus live update works fine with either jlu-3.5.1.34.jar or jlu-3.9.1.14.jar.


Etrack Incident: 2719915

SYMPTOM:
numspace and numinodes parameters should be less than 2TB. Symantec FileStore will not allow setting these variables to 2TB or more. 

DESCRIPTION:
numspace and numinodes parameters should be less than 2TB. Symantec FileStore will not allow setting these variables to 2TB or more. This limitation is because the quota component supports only 32-bits.

RESOLUTION:
In Symantec FileStore 5.7 and onwards, the 2TB limitation is removed. If you need quota support equal to or more than 2TB, please upgrade to Symantec FileStore 5.7 and subsequent 5.7 patch releases.

Etrack incident: 2645902

SYMPTOM: 
Replication jobs are failing with error "[SOURCE ERROR] Failed to get response
from destination cluster." There are some core dumps generated because of
a replication process segmentation fault.

DESCRIPTION: 
The maximum number of replication jobs is 64, but there are more stricter limits on the number of replication 
jobs that can be running in parallel at the same time. Replication uses a RAM-based file system for storing the 
transit messages. Each GB of this RAM-based file system can accommodate up to 8 parallel running jobs. The 
default size of this file system depends upon the amount of physical memory of the node on which replication is 
running. If the physical memory is less than 5 GB, replication limits its maximum usage for storing messages to 
1 GB of memory, which means the user can run up to 8 replication jobs in parallel at the same time. If the 
physical memory is between 5 GB to 10 GB, replication limits its maximum usage for storing messages to 2 GB of 
memory, which means the user can run up to 16 replication jobs in parallel. If the physical memory is greater 
than 10 GB, replication limits its maximum usage for storing messages to 4 GB of memory, which means the user 
can run up to 32 jobs in parallel at the same time. 

These default values can be changed using the following steps:

1. Stop the replication service.
2. Edit line "Net FS Size: 1024 MB" in file "/opt/VRTSnasgw/conf/sfsnet.conf" with the proper tpmfs size. 
This step is needed on all nodes of the cluster. 
For example: To increase the size of tmpfs to 2GB, edit the line as "Net FS Size: 2048 MB".
3. Above changes will be effective after starting the replication service.

To check the tmpfs size, you can use the following command:

#cat /opt/VRTSnasgw/conf/sfsnet.conf | grep "^Net FS Size:" | awk -F":" '{print $2}'

Note that the above values are based on a worst-case analysis. The typical memory consumption by these messages 
is very low because as soon as a message is sent, the corresponding memory is immediately freed. Thus, 
specifying a value for tmpfs size does not mean that so much memory is actually consumed. It is the worst case 
when replication is not able to send and apply messages quickly on the network. It is advisable that if you 
want to run more jobs than the above specifications, you should schedule the jobs at different times.

RESOLUTION: 
Increase size of replication tmpfs depending upon the number of jobs you want to run
in parallel.

V. NEW FEATURES:
-----------------

Etrack Incident: 2722268

A new tunable "fullspace" was added to the Storage> fs alert set and unset commands for 5.6 RP1 P4:

Storage> fs alert set numinodes|numspace|fullspace value [fs_name,...]
Storage> fs alert unset numinodes|numspace|fullspace [fs_name,...]

When a file system is 100% full, and the user continues to run write I/0s on the file system, performance might be slowed down dramatically. The NFS clients might get stuck for a long time while waiting for the I/Os, which can cause an I/O hang.

When a file system is 100% full, and some of the files are being overwritten, there can be some small spaces available for write I/Os.  But in this scenario, the file system might have problems managing the free spaces, hence the performance downgrade.

For a file system to run efficiently, users should always reserve some space for the file system, instead of using the space 100%. FileStore provides the function of file system full protection. When file system usage is over the space limit, alert value (80% by default), a warning message will be sent to the users. If the user continues to write I/Os to the file system, and file system usage reaches almost 100% (that is, 98%, tunable), all the NFS shares on the file system will be automatically changed to READ-only to prevent potential issues like a performance downgrade when the file system is full. By default, file system full protection is turned off. To activate file system full protection, a user can run the command "Storage> fs alert set fullspace 98" (set full limit to 98%).

Etrack incident: 2644277

Two new Antivirus> set commands were added for 5.6 RP1 P4:

o Antivirus> set tmpfssize size 
o Antivirus> set autoprotect holdonclose [yes|no]

The Antivirus> set tmpfssize size command enables and mounts a tempfs (temporary file storage facility) for accelerating Symantec AntiVirus for FileStore scans.

o To enable and mount a tempfs that can take up to size (MB) memory for
accelerating Symantec AntiVirus for FileStore scans, enter the following:

Antivirus> set tmpfssize size

where size is the memory used by the tempfs.

A minimum value of 2048 for size is required. Set size to 0 to unmount and
disable the tempfs.

For example, to enable a tempfs for Symantec AntiVirus for FileStore scans,
enter the following:

Antivirus> set tmpfssize 204

The Antivirus> set autoprotect holdonclose command determines if the file close system call is held by 
the Auto-Protect kernel module until the realtime scan finishes.

To determine if the file close system call is held by the Auto-Protect kernel
