How to destroy dump device?
 
Hello,
I have installed Solaris 11, and I need to destroy dump device, but I got an error:
Code:
# swap -l
No swap devices configured

# dumpadm -n
Dump content      : kernel without ZFS metadata
Dump device      : /dev/zvol/dsk/rpool/dump (dedicated)
Savecore directory: /var/crash
Savecore enabled  : no
Save compressed  : on

# zfs destroy rpool/dump
cannot destroy 'rpool/dump': volume is busy
How to destroy dump device?

As this one is the root pool, you cannot recreate it without destroying everything on it, including the OS.
