replace a pool

[xuqawigo]

Hello,
I would like to replace a 2 disk mirror pool (harddisk to ssd). problem is i haven't got any more available extension slot so the only way to add a disk is by removing at list one of the old ones. the net is quite slow there so it would really be of great help if I could import disk or something. currently there is a cache disk there which I don't need. so maybe that could be of help?

You can replace a mirror one by one... remove one of the disks (offline it first), then replace it physically with an SSD, then replace it in the GUI. Repeat for the other disk and you will have a new mirror (and 2 old disks with full backups on them).
