Question 4

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 : Svccfg - s filesystem/shadowd:defaultsetprop config_params/shadow_threads=integer: 16endsvcadm refresh filesystem/shadowd: default

B : Specify the -b < blocksize > option with the zfs create command and increase the value of < blocksize >

C : Use the -o -volblocksize=< blocksize >option with the zfs create command and increase the value of the default < blocksize >.

D : Svccfg -s filesystem/zfs: defaultsetprop config_params/shadow_threads = integer: 16endsvcadm refresh filesystem/zfs:default

Answer: A
