I knew I was missing something
.
The disk I need to newfs is named c4t50060E800589B220d0 but when I go ls /dev/dsk/ I see c4t50060E800589B220d0
sX where 0<=
X<=7. I remember reading something about the naming convention and I am sure that the number after the 's' means something but I have no idea which one to choose for newfs...
Also, I would like to replace an existing filesystem with the new one and I would like to have all current data moved as well. What's the easiest way to do it? I'd rather not move everything to external storage, remove old filesystem, create a new one and move the data over...
EDIT: I figured it out, I newfsed the second slice and mounted it with a temp name, I will move the data over, delete the old filesystem and rename the temp filesystem. Thanks bluescreen for pointing me in the right direction.
