Anthony, When the failed disk was replaced a RAID rebuild should have been initiated; that is a good thing. The RAID device will continue to operate in degraded mode until the rebuild has completed. I assume that's why it is still beeping at you. And the fact that something is beeping at you makes it sound like your RAID is managed in hardware, in which case operating system commands aren't going to give you an indication of what is happening. Is this true? Are your disks contained in an external disk enclosure? If so, what kind. -----Original Message----- From: linux-cluster-bounces@xxxxxxxxxx [mailto:linux-cluster-bounces@xxxxxxxxxx] On Behalf Of Anthony Sent: Friday, April 18, 2008 8:21 AM To: linux clustering Subject: Replacing a RAID 5 disk, then...
