<h3>Raid Sanity</h3>

I&rsquo;ve gotten cron log from one of my servers today which says:<br />
/etc/cron.weekly/99-raid-check: WARNING: mismatch_cnt is not 0 on /dev/md0 <br />
Quick look at<br />
cat /proc/mdstat<br />
showed, that array is allright.<br />
This mismatch_cnt value is the value of the blocks, that are not synchronized between RAID drives. On my server the value was<br />
cat /sys/block/md0/md/mismatch_cnt<br />
and partition was md0, which is BOOT. SO, I quickly found the way to repair the problem by using<br />
echo repair &gt;/sys/block/md0/md/sync_action<br />
watch cat /proc/mdstat<br />
and after repair is completed<br />
echo check &gt;/sys/block/md0/md/sync_action<br />
watch cat /proc/mdstat<br />
After those operations the value of desynchronized blocks went to 0 again:<br />
cat /sys/block/md0/md/mismatch_cnt=

<h3>Disk layout for scsi to drive mapping</h3>
