Allocated Snapshot Space Exceeded the Configured Limit

[Deltr0nz]

I am getting a daily error that one of my arrays has exceeded it's configured snapshot space. What is my best option to resolve this error?

Here is my output from show snapshot-space

Pool: A
Limit (%Pool): 10%
Limit Size: 10.7TB
Allocated (%Pool): 0.9%
Allocated (%Snapshot Space): 8.6%
Allocated Size: 931.0GB
Low Threshold (%Snapshot Space): 75%
Middle Threshold (%Snapshot Space): 90%
High Threshold (%Snapshot Space): 99%
Limit Policy: Notify Only

@Deltr0nz 

Your Limit Policy set as Notify only and that's why you are getting notified only. There is another policy can be set which is deletion of snapshots as well based on configured retention priority.

Otherwise you can increase snapshot space from 10% to 15% and then check further.

For example. For Pool A, limit the maximum amount of pool space that can be occupied by snapshot data to 15 % and limit policy to delete use below command,

# set snapshot-space pool A limit 15% limit-policy delete

Above command is just example, you need to go through Command Line guide and review your setup before modifying anything.

Hope this helps!

Hi Subhajit - I have increased it to 15% and will see if I get the error again this evening when it runs.
