Thin provision question

Added by Steve Frank over 3 years ago

My test box is now up to 800GB of underlying space, I'd like to create a zvol on my first pool that's about 1.5TB in size, using a thin provision. I have another drive I might be able to get into this test box hence the size setting (and learning). When I try to do this, I get the following error:

cannot create 'pool1/lun1': zvol size exceeds limit for this system

It >will< let me create a zvol of 1TB, but it won't let me go beyond that.

any ideas why?

Thanks again!

I know this is old but I stumbled upon this and my have why.

I'm currently running a 32-bit system (yeah it's what we had lying around), I have 1.42TB of usable zpool space, can't allocate more than 1.25TB to a zvol.

cannot create 'Stor1/VM1': zvol size exceeds limit for this system

I believe this is a limitation of the 32-bit system. I guess I can create multiple zvols, but that is kind of annoying.

We'll be upgrading to 64-bit sometime in the future anyway.
