Again.. don't use the word metareplace...
Your Primary disk seems to have failed. So you will need to detach the primary disk from the secondary and then replace the disk drive with a new one of the similar geomatrical size. copy the partition table from the sec disk and then attach it back
But, I don't understand the follow part in metastat message
The above information seem to show that there is only one submirror (d16) running on d6 on my primary harddisk (c0t0d0). Can i conclude that
the mirror is broken? and there is no way to recover my data from my secondary disk.
possibilty is there, but before confirming, can you post the metastat -p command? But need to check whether it was attached at the first place (i doubt so)
oh my... As suspected, your slice 6 was not attached when your mirroring was done. SO now, since only the ONLY submirror which was working had failed, you will definitely loose all your data in slice 6 and will have to restore them. d26, the second submirror will not have the latest data that you had in the system before the primary disk failed. :o
So, Slice 6 is dead. Data will be lose. And, I have to replace c0t0d0.
Now, I want to know if there is a possibility of restoring s0, s1 and s7 after replacing a new drive.
