[OpenIndiana-discuss] [zfs] problem on my zpool

[Clement BRIZARD]

The disks are in a Fractal XL case which have little rubber pad to 
contain vibrations.
As long as it works I will leave it. When I will have some money I will 
build a proper server

Once the resilvering is done, should I do a scrub job ?
