Options for replacing a single disk pool with a smaller sized disk?

[markymark832]

hi the title says it all really
i have a 2tb hybrid hdd/ssd drive i was gifted, so i put it in my NAS just as a little additional storage, created a pool with it, and started messing around with iocage/jails on it. there's about 150gb of data on this disk ( hardly utilised)
forgot about it's setup and carried on.. two years later
Device: /dev/da7 [SAT], Self-Test Log error count increased from 7 to 8.
Device: /dev/da7 [SAT], 8 Currently unreadable (pending) sectors.
Device: /dev/da7 [SAT], 8 Offline uncorrectable sectors.

so I have brought a 1tb ssd drive.
but for the life of me i can't see the best way to replace this.
all guides I see are for replacing disks in zvols and reslivering them, which I have done before absolutely fine with my main storage areas before.
just unsure of best way to do here? is there a way? to setup a new pool duplicate the pool then remove the old drive? then going to point all my jails and vms to the new pool?

thanks for any advice given

With such a small amount of data I wouldn't even bother to do it like this. Why not add the SSD as a new pool and transfer the data? And if there is no SATA connection left, just use a USB drive (or two if you value your data) as temporary storage.

Thanks for the reply, I thought this was going to probably be the only real option, my concern is hooking all the jails and vm's back upto the system once I have moved it all, is it simple enough?

If you follow this process, but first stop all jails and VMs including the rename steps, you will end with a system that's working exactly the same as now, but with the new disk in place. The process is the same for larger or smaller disks.

Howto: migrate data from one pool to a bigger pool

There have been a lot of posts recently about how to move data from one pool to another. Usually it's because folks want to upgrade to a much larger pool and the drive-by-drive resilvering process will take too long. I've recently gone through this as well. Here are the steps that I followed...
