RAID checks appear as resyncs in the log on RHEL5

Issue

• The weekly RAID check is occurring, but despite the settings for check only(not repair) the raid filesystem seems to be rebuilding anyway.

/etc/sysconfig/raid-check
ENABLED=yes
CHECK=check
# To check devs /dev/md0 and /dev/md3, use "md0 md3"
CHECK_DEVS=""
REPAIR_DEVS=""
SKIP_DEVS=""
