[OpenIndiana-discuss] System Panics after deleting zvol

[George Wilson]

Matt,

Are you able to create a pool on another disk? If so, then you could try 
to create a new zvol on the new pool and copy over the contents from the 
old zvol using 'dd'. Then you could try to share out the LU from the new 
pool.
