Storeonce store taking ages to start

We have DP 7.01 with Software storeonce store configured .

Each time we reboot the CM the storeonce store is taking more than one hour to initialize

 

C:\Users\admlerc>storeoncesoftware --list_stores
Starting stores in progress. Please retry later.

 

I wonder if it's "normal" or if there something wrong in the time is taking

thanks

Re: Storeonce store taking ages to start

I checked our lab cases for this, and found a couple of things that may be helpful.

 

One suggestion is that the Store was not shut down properly, and will probably take a long time to start. Since the store (in this lab case) has more than 10 TB of data of deduped data, this isn't surprising. Therefore, as a first step, we need to let the store startup run for as long as it needs. We can keep monitoring the Windows Application event log to check if the startup process completed or not. Also, we can try starting the StoreOnce service with logging enabled, so that we can track any other errors that might crop up.

 

Another suggestion was to see if you are getting any warnings about Low Memory availability, written into the Application or System Event log on the StoreOnce server

 

If so, there is a Microsoft article about Memory utilization

 

the Microsoft Dynamic Cache Service as already recommended.

 

Also, it is suggested that you set two environment variables on the StoreOnce server by editing the file

 

       ProgramData -> Omniback -> omnirc

 

On the StoreOnce server, stop the Data Protector INET service. 

 

This file does not exist by default.  If you don't have it, it can be created using Notepad.

Add these lines to the file

 

OB2_STOREONCESOFTWARE_MEMORY_METRICS_WARNING_AT=10

OB2_STOREONCESOFTWARE_MEMORY_METRICS_ERROR_AT=5

 

Save the file as

 

                 Program Data -> Omniback -> omnirc 

 

Make sure that the filename has no extension, like ‘txt’ or ‘tmpl’

Restart the Data Protector INET service.

 

OB2_STOREONCESOFTWARE_MEMORY_METRICS_WARNING_AT=n
Default: 25
This variable defines when the low free memory warning is going to be written into event/system
log. The unit can be either % or Megabytes based on OB2_STOREONCESOFTWARE_MEMORY_METRICS_UNIT
variable.

OB2_STOREONCESOFTWARE_MEMORY_METRICS_ERROR_AT=n
Default: 10
This variable defines when the low free memory error is going to be written into event/system
log and all transactions to the store are going to be rejected. The unit can be either % or
Megabytes based on OB2_STOREONCESOFTWARE_MEMORY_METRICS_UNIT variable.

Also, please be sure that you have the latest StoreOnce patch installed DPWIN_00630 by running the command from the MS-DOS prompt on the cell manager

 

           omnicheck -patches -host [StoreOnce Media Agent hostname]      Don't include the [   ] marks

 

If none of this helps, you will probably need to open a case with the response center, and have StoreOnce debugging enabled and also send the Application and System Event logs from the StoreOnce server

Re: Storeonce store taking ages to start

Hi ,

the server has 17TB of storage available and only 7TB used .

 

The latest patches has already been installed , including the 630 for SOS

 

Can you explain what you meant about

     there is a Microsoft article about Memory utilization

     the Microsoft Dynamic Cache Service as already recommended.

 

I've added the two configuration lines for MEMORY warning and error as our event log was filled with warning stating that there was 21% memory left

 

thanks
