You don't. You remake the pool.

This is why you should be careful and use -n before running zpool commands.

Also, why do you have a 2-disk raidz1? That's a much more expensive and inefficient mirror.

[kolinfluence]

2 disk raidz1 isnt that how raid1 shld be?

what's the suggestion "remaking the pool"? i have 0 disk sata cable left. all the other sata disks are running.

[rincebrain]

I mean you delete the pool and make a new one. You have done something you cannot undo.

raidz1 is not a mirror. raidz1 on 2 disks is similar to doing RAID5 on 2 disks - a very inefficient way of doing things for no different redundancy properties to a mirror.

[IvanVolosyuk]

Yes, removal of disks is very limited in ZFS and doesn't work if there is a zraid in the pool. It is not very efficient either, as there is a translation table, which should probably be mostly empty in your case. It looks like a half-implemented feature to me. Anyway, your options are to make a mirror from the disk you added or copy or send the data out and re-create.
