You created a new zpool. Now you need to migrate the existing ZFS file system from
pool1/prod to pool2/prod. You have these requirements: 1. Users must have access to the
data during the migration, so you cannot shutdown the file system while the migration takes
place. 2. Because you want to copy the data as quickly as possible, you need to increase
the server resources devoted to the ZFS migration. Which method would you use to modify
the ZFS shadow migration daemon defaults to increase the concurrency and overall speed
of migration?
A.
Use the-o -volblocksize=<blocksize>option with the zfs create command and increase
the value of the default <blocksize>.
B.
Svccfg-s filesystem/zfs: default setprop config_params/shadow_threads = integer: 16
end svcadm refresh filesystem/zfs:default
C.
Specify the-b <blocksize> option with the zfs create command and increase the value of
<blocksize>
D.
Svccfg-s filesystem/shadowd:default setprop config_params/shadow_threads=integer:
16 end svcadm refresh filesystem/shadowd: default
