Subject: Creating new raid5 or 6 with --assume-clean
Date: Sun, 1 Dec 2013 22:07:07 -0500 [thread overview]
Message-ID: <20131202030707.GB19621@animx.eu.org> (raw)
This is a general question, but I'll give a specific.
If I create an array with assume clean and proceed to write to the device,
what happens with the parity?
EX:
mdadm -C /dev/md0 -n 4 -l 6 -e 1.0 -b internal -c 128 --assume-clean \
sdc2 sdd2 sdf2 sde2
Then:
dd if=/dev/zero of=/dev/md0 bs=1M
When it finishes, will all the parity blocks be correct for raid 5 and
raid6?
Would changing md/stripe_cache_size up/down make a difference to the
parities?
