upgrade cache using 6.9's multiple pools?

[acosmichippo]

Hello all,

 

Apologies if this has been discussed elsewhere, I tried searching but didn't find much.

 

Anyway, I'm planning a cache upgrade and was wondering if this plan would work using 6.9's new ability to have multiple cache pools. I had issues the last time I did a cache upgrade on 6.8 so I'm trying to avoid using the the 6.2+ method if possible.

 

1) "old" cache is currently 500GB, leave as-is for now

2) create "new" cache pool of 1TB alongside "old" cache

3) stop all docker containers, VMs, etc, and copy data from "old" cache directly to "new" cache

4) change share settings from using "old" cache to "new" cache

 

just seems like this would be a lot faster and easier since it's one copy going SSD>SSD instead of two copies SSD>Array>SSD. are there any issues with this? or do we need to stick with the 6.2+ method?

 

Thanks!

You can do that, but need to copy the files manually, since the mover can't do it from pool to pool

yeah that's what I figured, thanks!

You actually need to go to Settings and stop the Docker and VM Manager services, since these will have files open even if each individual container or VM is stopped.

yep, did it this morning and so far seems to have worked just fine.
