Hi. It is very unfortunate to return to the forum only with problems, but I have another one.
Before my recent experiments I have stable 2-way mirror root-on-zfs setup with following characteristics:
Pretty ordinary setup indeed.
But as preparing for 13.0-RELEASE with fresh new zfs (special allocation class vdevs) features I bought Sun Oracle F80 Flash Accelerator. This piece of hardware is simply four 200GB ssd's and LSI controller in IT mode (JBOD) residing on single board. It visible from system as:
Disks are:
So far so good.
I have added two of them as special device to my zroot pool:
And after reboot I have:
Special devices cannot be detached from pool. Everything is readble and in good health when booting from live CD. Can be this solved by some manipulations, or I need recreate my pool? Can this be result of invisibility this SSDs from BIOS (as stated from Sun documentation: "Note - The Sun Flash Accelerator F80 PCIe Card cannot be used as a boot device")? Thank you in advance.

I have added two of them as special device to my zroot pool:
Code:
pool: zroot

da0 ONLINE 0 0 0

And after reboot I have:
Code:
ZFS: i/o error - all block copies unavailable
ZFS: can't read MOS of pool zroot

Special devices cannot be detached from pool. Everything is readble and in good health when booting from live CD. Can be this solved by some manipulations, or I need recreate my pool? Can this be result of invisibility this SSDs from BIOS (as stated from Sun documentation: "Note - The Sun Flash Accelerator F80 PCIe Card cannot be used as a boot device")? Thank you in advance.
