Doug,
Thank you very much for that; a great relief off my shoulders.
You are right - there is a config file located in
/etc/sysconfig/raid-check. I've changed ENABLED to no.
However there is real value in doing that check, at least occasionally. It
catches latent read errors.
You might want to run it only every couple of months, and you might want to
wind down one of both of the /proc/sys/dev/raid/speed_limit_* numbers so
there is minimal impact on your system.
sorry if i am hijacking, but i got a report from one user that the
scheduled scrubbing is severely impacting responsiveness, lowering the
speed_limits seems to help a bit, but he reports it is still sluggish,
i always believed the check should use idle time, and not impact
performance that much. could it be scheduler related?
regards,
L.
