I have a partition set up as software RAID-1 on a CentOS 5.3 machine. Today, the system was rebooted, when it came back up I noticed that it had started to resync. It completes the sync, then immediately starts again.
From the log: Jul 29 09:46:02 cbserver kernel: md: syncing RAID array md2 Jul 29 09:46:02 cbserver kernel: md: minimum _guaranteed_ reconstruction speed: 5000 KB/sec/disc.

Any idea what is causing this? And how to make it stop?
Thanks!
