Scrub?

dildano · 27. Juli 2014

Sorry in advance if this is a stupid question. On my old Netgear ReadyNAS, I can schedule a RAID scrub to run periodically to search for and address defective blocks to reduce the probability of silent data corruption. Is there a way to do that in OMV?

I believe it is setup automatically to be done monthly, with mdadm, on Debian based systems.

How would you know if it's running? How can you see the results?

You can tell by the status in the Raid tab in the OMV web interface. If there was a problem, it would probably be logged in /var/log/messages

Your old ReadyNas was probably using a much older version of mdadm. You probably don't need to worry that much about it. If you want to manually run a check (cron job), do:

/usr/share/mdadm/checkarray -a /dev/mdX

Yes, my ReadyNAS is still running Debian Etch, I believe. I guess things have evolved since then. Thanks for the help!

OMV does a scrup every first Sunday in a month.

Code

root@openmediavault:/etc/cron.d# cat mdadm
#
# cron.d/mdadm -- schedules periodic redundancy checks of MD devices
#

# By default, run at 00:57 on every Sunday, but do nothing unless the day of
# the month is less than or equal to 7. Thus, only run on the first Sunday of
# each month. crontab(5) sucks, unfortunately, in this regard; therefore this
# hack (see #380425).
57 0 * * 0 root if [ -x /usr/share/mdadm/checkarray ] && [ $(date +\%d) -le 7 ]; then /usr/share/mdadm/checkarray --cron --all --idle --quiet; fi

You can find the evidence in /var/log/messages and /var/log/daemon
