v12 Use older IOFilter after upgrade?

[william.bishop]

Hello all;

v12 veeam, just upgraded to the July rollup, but it's requesting (obviously) to upgrade the iofilter, which will require a maintenance mode. This cluster is already tight, and I'm waiting for the new cluster to be turned up to move some load over to it.
2 questions:
1. Would it be possible to leave the current iofilter in place for a short time and still run cdp?
2. Are there any gotcha's to doing so (other than obviously not the preferred goal)?

It's possible to leave the I/O filter in its current state. The configured policies (along with disaster recovery actions) would work fine, but you wouldn't be able to create new ones until you update the I/O filter. Thanks!

Thank you very much! I'll give it a go. Shouldn't be long until I can upgrade the filters, I've got an outage coming up.

Thanks again;

William

You're welcome. Let us know, should other help be needed. Thanks!

Oh well, the dream lasted about 2 minutes. "IO filter running on host XXXX is outdated, failed to enable CDP."

Looks like they built in some prevention.

Thanks anyway,

William

Looks strange, at least to the actual R&D folks behind this functionality. They will try to reproduce the issue in their test environment. Will let you know about the outcome. Thanks!

Hey, if anybody is going to find an outlier issue, its us.....lol.

The R&D team has confirmed your findings and apologizes for providing misleading information. Sorry again for the confusion caused.

No worries, it's actually a logical pathway, to reduce possible future issues. I am not disappointed in the least. Please pass along my good wishes to them.
