Can I safely ignore any mismatch_cnt errors on my Fusion-io array?

The root user of a system using Linux software RAID-1 or RAID-10 of Fusion-io ioDrives (aka IBM High IOPS SSD Adapters) may occasionally receive a message similar to the following:


WARNING: mismatch_cnt is not 0 on /dev/md0

For RAID-1 and RAID-10 arrays using Linux software RAID, these messages are normal and considered a known bug in Red Hat Enterprise Linux 5. These messages will be removed in a future release of the operating system.
