When performing a dry run for deduplication, fsdedupadm may take a ‘-o
threshold=percentage’ argument. This argument will initiate an actual deduplication run
when the metric reaches which given value?
A.
the percentage of file system disk usage
B.
the percentage of expected savings
C.
the percentage of duplicate file names
D.
the percentage of the dry run completed
B.
from the manpage:
dryrun Initiates a deduplication dry run on the file system speci-
fied by mount_point. You can specify the -o threshold
option, which causes the fsdedupadm command to deduplicate
only if the expected savings cross the specified threshold.
You can initiate a dry run only on a file system that has not
been deduplicated previously.
