Hmm..This time would vary based on the server resource configuration and load.

By the way, Jim, did it work for you? Were BMR enabled backups worked too during purge execution?



Level 6

Since upgrading im starting to see status 13's on first runs little more frequently than what im use to.  Most if not all will retry a little later and complete but they all use to run just fine the first go.  I know i have an older appliance (5200) but is anyone else possibly seen an increase in these?

Im guessing i need to rearrange my policies to see if that makes a difference but that sometime is hard when the issue is different machines everynight.

To reply to Mandar: the server was doing nothing in terms of backup. 8G memory , all CPUs available. Not the fasted CPU but hey. It worked so worthwhile doing and now the verify takes a minute. Im sure I've posted this reply elsewhere.

I have 2 5220 and has successfully upgraded 1 from 2.5.2 to So far so good.


For the second appliance, the MSDP, it is 90% used and has 5.2 TB free.


WIll i be able to upgrade the appliance in the current situation?



Level 4

I have 2 5220 appliances both were running on 2.5.3.


I upgraded one and it is working fine. For the second one, dedup pool has only 10% (7TB) free. Will i face any issues if i go ahead with the upgrade?

Are you using MSDP pools? If so I saw on a slideshow recently that it is recommended to have 12% available for the MSDP conversion when updating from 2.5.x to 2.6.x.

MSDP free space required is listed at 12 %

I'd probably try to get it down to 15 tho

<insert shameless plug for additional storage shelf here>

Try to process your queue all the way down and let compaction run. You will free up a lot of space and make you safe for the upgrade. But you will need extra storage if your dedupe is that full, you will get into a LOT of trouble if you let it go like that...

Level 4

Yes. I am using MSDP.


I have already processed the queue and compaction multiple times. But still no luck...:(

And yeah i understand the risk of running the MSDP with only 10 % full.

We have ordered the hardware for 2 new media server and once it is ready, i am planning to split clients between the media servers and do the clean up activities.


So i belive my only option is to wait for the new media server and upgrade this appliance once the MSDP usage is below 80%-85%


Thanks guys...

We've only noticed that our appliance is giving the same error (also on Appliance -> Status). We only noticed this after the upgrade to as we zere experiencing some connectivity issues from certain subnets.

Checking back, the issue was also present on the appliance when it was still on It never caused any issues though.

Were you able to resolve this error?

Resolved -- make sure nothing is wrong with the network config files and the clish will be able to parse the files correctly.
