[OpenIndiana-discuss] problem adding a mirror disk to rpool

Tue Jan 3 10:32:22 UTC 2023

Indeed, finally, I created on the second disk of the mirror, with fdisk, 
the same partition (solaris 2, 100%, bootable) as on the first disk, 
then I copied the vtoc using prtvtoc anf fmthard, then used zpool 
replace and zpool clean and everything is now OK, according to zpool 
status. It was the fdisk phase that was missing in my original procedure.

Did the resilvering also copy the booting stuff or should I run 
installgrub ?

Thank you all for your help
