StoreOnce error

Hi,

 

My StoreOnce 4700 device used as for several Catalyst stores has failed.  Several (but not all) of the stores are showing as "Failed to start" and so Data Protector backups are obviously failing.  Restarting the device has no beneficial effect.

 

The failed stores show a completely incorrect dedupe ratio of several million to one!

 

The event log shows a last error of, "[ssid1]: D2DManager process state has changed: Warning to Critical (SMM, ObjectStore)".

 

Any suggestions?

 

Thanks,

 

John

Re: StoreOnce error

This error may be caused by previous errors encountered when wrting to StoreOnce stores

 

This error happens because HK fails to process one of the jobs for the store in question

 

Jobs are located at:
S:\StoreOnce\StoreOncelibrary\dvol_00000004\committed\storemgr\store.d\store_04\retired
Where 04 can be replaced by all volumes (24 all together)
 
Please stop the SOS (StoreOnce Software) service and check the mentioned folders.
Depending on the number of subfolders in retired folder please do the following:
  • If only a couple of folders, then delete them and restart the service.
This should start also the store in question
 
If the problem persists, open a case with tehe response center.  To help things along enable StoreOnce tracing
 

from the command prompt on the StoreOnce agent

 

          cd \Program Files\Omniback\bin

          sc stop Storeoncesoftware

          sc start Storeoncesoftware -–log_level=tracing

 

If the Store still refused to start, disable StoreOnce tracing

 

from the command prompt on the StoreOnce agent

 

          cd \Program Files\Omniback\bin

          sc stop Storeoncesoftware

          sc start Storeoncesoftware -–log_level=none

 

IN the folder on the StoreOnce media agent

 

   Program Data -> Omniback -> tmp

 

look for long filenames that contain 'storeoncesoftwareCore' as part fo the filename

Re: StoreOnce error

Hi Bob,

 

I think you may have missed the fact that it's a StoreOnce 4700 appliance and not a software dedupe store.....

 

Thanks,

Re: StoreOnce error

Hi,

 

This problem  is device specific.

You should ask the same question in different forum - hardware (not software).

Re: StoreOnce error

The problem was caused by an issue with the StoreOnce software on the 4700 appliance.

 

If each StoreOnce 'segment' becomes over 70% full then it can cause the Catalyst stores to fail.  This is an example of poor design by HP.  In addition, access to the operating system of the StoreOnce appliance is only limited to HP Support engineers.  Why is this?  They are not the only people with Ibrix knowledge.

 

See: http://h30507.www3.hp.com/t5/Technical-Support-Services-Blog/DPTIPS-StoreOnce-3-11-4-software-release-addresses-Shellshock/ba-p/173368#.VLEXsaLHzDc for details.

 

Once I'd got through the pain of the first-line support, I worked with an online Mission Critical engineer (who was very good BTW) who told me to delete a lot of backup data to get the stores back online.  Luckily I had an extra disk tray of 24TB to add to the device to give me the extra space to fix the problem.  Otherwise I would have had to delete many TB of backups.  Most people would not have this luxury.

 

I then upgraded to v3.11.4 (from v3.9.4) to get rid of the problem.

 

So there you go.

 

John
