replacing broken drive

[pomah]

Hello

I have two 1 tb drives, one of them seems to be failing, 2 cache sum errors, running smart to see what is what.

But, main question is this, if I need to replace the broken drive, I want to upgrade storage, so lets say I will by a 2 or 3 tb as a replacement.

I wont be able to use more than 1tb, since the old healthy drive will be in the pool, but what happens when I later on will replace the last 1 tb with a similar 2 or 3tb, will the pool automatically recognize the new free space and make it available?

I am using a ZFS pool today, no raid.

If you have two disks in the pool, you're using RAID of some sort. If the disks are striped, you'll see the extra capacity right away. If they're mirrored, you'll see it once you replace the other disk.

If the disks are striped, you'll see the extra capacity right away.

And if the disks are striped you will see your data instantly gone when you pull that failing drive. Had you provided us a little more detail like your pool configuration the answer would have been super simple and specific to your configuration.
