[OpenIndiana-discuss] destroyd a raidz under zfs-fuse and problem with a rpool (the system-disk)

[Johan Nilsson]

Tried to see if i could see my zfs under zfs-fuse with Ubuntu, but apt-get
hang during install of zfs-fuse, trying mount zfs. So when I boot back into
openindiana my zpool last disk was broken.

I tried to find a way to fix it, but i don't manage to do that. During I
tried to fix c2d1p0, it's get the long number.

There also are an error in rpool on my system disk, but that was before I
tried to mount my raidz under ubuntu. Is there an error on the harddisk?

My question is, how do I fix my raidz/zdisk?

Is there a way to fix the broken files i rpool, ..i don't have any backup.
Is there a way to check if my disk are bad, it an very old one.

My zpool status down under.. /Cheers
