Hi Everyone,

I'm running CentOS 5.5 which a stock version of mdadm. I have 2 physical 
disks in a RAID1 setup. Each disk has 4 md partitions on it.

I'm experiencing the issues associated with the raid-check script every 
Sunday morning, where whatever is happening, a re-sync happens. Doing a 
little reading around Google, I see that this is probably caused by the 
mismatch_cnt being non-zero, which apparently is normal for RAID1 
devices. According to this bug:

https://bugzilla.redhat.com/show_bug.cgi?id=566828

someone has made a patch for RedHat so that mismatch_cnt isn't checked 
on RAID1 setups. However, since I don't use RedHat, and I don't really 
want to compile mdadm from scratch, is there a workaround for this? I 
don't want to just disable the raid-check script, as I think it does 
some other important checks which are useful for RAID1.

Any help would be appreciated

Thanks
