Hello All
I read this thread Resilver/scrub times? for a few minutes
and I have recognize that I dont know the different between
Resilvering and Scrubing. Shame on me. :-(
Scrubbing is used to check the contents of a pool by reading the data
and verifying its checksum.
To quote the man page:
Scrubbing and resilvering are very similar operations.
The difference is that resilvering only examines data
that ZFS knows to be out of date (for example, when
attaching a new device to a mirror or replacing an
existing device), whereas scrubbing examines all data to
discover silent errors due to hardware faults or disk
failure.
I dont find some declarations in the man-pages and I know the command
to start scrubing "zpool scrub tank"
but what is the command to start resilver and what is the different?
There isn't one. resilvering starts automatically when a dive is replaced.
