Raid1


Hi..everybody, I had created software RAID, on last 8 days back, & after configuriguring also I had forcefully checked for 4 times(4days) of the RAID arrays by using below commands

echo check > /sys/block/md0/md/sync_action
echo check > /sys/block/md1/md/sync_action
echo check > /sys/block/md2/md/sync_action
echo check > /sys/block/md3/md/sync_action
echo check > /sys/block/md4/md/sync_action
echo check > /sys/block/md5/md/sync_action

for one week I did not found auto resync. Today when I ran cat /proc/mdstat I found auto resync was going on 2 md devices, & for other 3 md devices the status was as resync delayed. I checked crontab & there was no entry for crontab, for any of the user including root. But I don't want to run this auto resync at the day time. If the auto resync is must at least once in a week, I would like to schedule it at night time. So I searched internet to disable auto resync, but I did not find the solution. So guys I request you, how can I disable this auto resync?

Regards
Ananth

I tried RAID1 once and got tired of waiting for it to synch. Everytime the machine was rebooted, I had to wait hours. I surmised this is only good for a machine that is running 24/7. For a personal machine or a server at home, I would rather use backup software and run it everyday.

I found a good article on software RAID1, which may help you understand and monitor the setup you have now.
