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
- If only a couple of folders, then delete them and restart the service.
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,
John

Re: StoreOnce error
Hi,
This problem is device specific.
You should ask the same question in different forum - hardware (not software).
Regards

SolutionThe 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
