The pool layout:
1. vdev1 (multi disks with hardware raid5)
2. vdev2 (multi disks hardware raid6)
3. vdev3 (single ssd)
4. vdev4 (single ssd)
No software raid on any of these device.
Wha I want:
1. moving data on vdev3 & vdev4 to vdev1/vdev2
2. removing vdev3 & vdev4 safely without any data loss
Why I want to do this:
1. I made mistake to create cachey vdev for this pool, the two ssd now are normal vdev but not cache
2. add there is hardware issue on one of the ssd
3. the broken ssd cause the whole pool down sometimes
Now the system is running well, but I don't know when will it break down. It seems that every two days the issue will be back...
I've searched the net, but can't find the solution.
Thank you very much!
