Description

Data corruption may occur on Access 3340/3350 appliance running version 8.0 or 8.0.100 when a filesystem is BOTH
- WORM enabled
- AND uses a blocksize of less than 8KB.

NOTE:
- WORM Veritas Data Deduplication (WORM MSDP) is NOT affected by this issue.
- Any non WORM filesystem is NOT affected
- Any filesystem with a blocksize of 8KB is NOT affected

 

To check if any filesystem has the potential to be affected by this issue:

Use the Access cluster clish to inspect each filesystem

CLISH> storage fs list <filesystem>

a) In this  example, the block size is 8KB and the filesystem is not WORM enabled.
Therefore, this filesystem is not affected by this issue.

Block Size:                    8192 Bytes
[...snip...]
WORM Enabled:                  No

 

b) In this example, the block size is 8KB and the filesystem is WORM enabled.
Therefore, this filesystem is not affected by this issue.


Block Size:                    8192 Bytes
[...snip...]
WORM Enabled:                  Yes

 

c) In this example, the block size is 1KB and the filesystem is WORM enabled.
As this filesystem fits both criteria it has the potential to be affected by this issue.

Block Size:                    1024 Bytes
[...snip...]
WORM Enabled:                  Yes

 

Action Required

If any filesystems are identified as being at risk:

For appliances at version lower than 8.0
Do not upgrade to either 8.0 or 8.0.100
The issue will be fixed at version 8.1 and 8.0.200. Wait for the release of the fixed version and upgrade directly to it.

8.0.200 is now available.
https://www.veritas.com/support/en_US/downloads/update.UPD445144

For appliances already at version 8.0 or 8.0.100
Immediately stop using any affected filesystems, offline them using below command and contact support for assistance.
 

CLISH> storage fs offline <filesystem>

Initially, Patch 8.0.100.1 was release to fix this issue. However, this has now been superseded by maintenance release 8.0.200. Please use 8.0.200 in preference to 8.0.100.1.

However, all identified filesystems must first be checked before it is applied. Please contact support for assistance before applying the patch.

For appliances already at version 8.0 or 8.0.100 that do NOT have any at-risk filesystems, and want to use WORM functionality, please apply patch 8.0.200 before enabling the WORM feature on any filesystem.

Note, the upgrade path to 8.0.100.1 is only from 8.0.100.For appliances at 8.0  the upgrade path will be a 2-step process 8.0 -> 8.0.100 -> 8.0.100.1
