CDP 3.12.2 Release Notes

CDP 3.12.2 (Stable) Release Notes

This release includes 4 product editions: CDP Standard Edition, CDP Advanced Edition, CDP Enterprise Edition, and Data Center Console.

IMPORTANT NOTE(S):

Release 3.12.2 This update to 3.12.1 contains two improvements:

• MySQL backups on servers that have crashed tables will continue without failing. The crashed tables will be skipped and the backup process will continue.
• Additional data will be recorded in your disk safe which will aid in debugging if there is ever a problem with your disk safe. This update will also correct a potential issue if recovery points have been merged out of order.

If you have already installed or upgraded to the 3.12.0 or 3.12.1 agent, there is no need to install the 3.12.2 agent as no changes have been made to this application.

Release 3.12.1 Addresses Issues with 3.8.x Upgrade and MySQL Discovery Performance:

There have been a small number of issues with customers upgrading from 3.8.x or who previously had one of these versions installed. This update will correct the problem for these customers experiencing issues upgrading or running CDP Server after upgrading to 3.12 and prevent this issue on future upgrades.

This release also corrects a performance problem with discovery and backup of MySQL databases which was introduced in 3.12.0. This fix returns performance to speeds achieved in 3.10.

Upgrading customers may experience a delay when starting the WebUI:

• Please be patient as important updates are in progress. The log file will display "CDP Started" when all database updates are complete.

  Windows customers can watch their logs using Wordpad but will need to close and reopen the log file to see progress (example default path for Enterprise Install on Windows: C:\Program Files\R1Soft CDP Server Enterprise\log\server.log).

  Linux customers can watch their server log file using the following command: tail --f /usr/sbin/r1soft/log/server.log

Customers Upgrading with Customized Heap Settings:

• The upgrade will change the java heap size to 50% of physical memory if the server.conf file has been customized with a higher value. Reserving more than 50% of a system's memory for the Java Heap can result in situations where not enough memory is available for non-heap memory to the CDP server, or for other applications running on the system.

MySQL Users:

• MySQL instances no longer need Federated table support to be protected.

Known Issue with Windows Restoring to Alternate Locations at Drive Level

We have discovered an issue in Windows where restoring to an alternate location at drive level (e.g. C:\ to G) causes a restore failure. The work-around is to drill down one level, select ALL, then restore to an alternate location.

Known Issue for Policy SOAP API Archiving Support

At this time Archiving is not supported in the Policy API however there are plans to add support in a future version.

Known Issue for Linux Agents

We have discovered that many versions of the utility 'fdisk' are broken and do not correctly create the embedded partition ID in the partition table (it is all zeros).CDP 3 uses this partition ID to correctly locate partition tables on your server and is required for backing up partition tables.

If you see something like the following message: "Can not back up /dev/xxx partition since /dev/xyz partition has the same identifier"; Then you will need to manually create a partition id.Please see the following knowledge base article:http://wiki.r1soft.com/display/kb3/Creating+a+unique+partition+id+with+fdisk

Known Linux Kernels with Severely Broken Ext4

There was an issue with Ext4 introduced in "vanilla" Kernel.org kernel 2.6.32 and has been patched and released "down stream" into various Linux distributions.  When any Ext4 file system snapshot is performed on an effected kernel the file system can deadlock causing a hung or crashed operating system.

**This is a Linux kernel bug completely out of the control of R1Soft**

Do not use the following Linux kernel versions with Ext4:

• Ubuntu Lucid (10.04) Betas and Release Candidates - we have reports that Ubuntu Lucid 2.6.32-24.41 and greater are fixed
• Ubuntu Maverick (10.10) Betas and Release Candidates
• Debian 6 (Squeeze) Betas and Release Candidates
• Fedora Core 12 Betas and Release Candidates
• Xen (4.0 / 4.1) - Do Not use Ext4 on 2.6.32-5-xen - 2.6.32-35-xen_02
