Hi All, Here is the problem that I am currently experiencing on a production server. I have a Software RAID1 array that consists of two 36GB SCSI 160 drives. I cat'd out /proc/mdstat and here is what was returned: Personalities : [raid1] read_ahead 1024 sectors md0 : active raid1 sdb1[1] 32507392 blocks [2/1] [_U] md1 : active raid1 sdb2[1] 2562240 blocks [2/1] [_U] unused devices: <none> The machine is still running, however it looks as if one of the drives has failed. The machine has not been running very long, and I am not 100% sure if the RAID array was ever running on both disks. Is there anyway to tell if a drive has actually failed, or if the array has not been initialized. The array was constructed during the setup procedue, and the machine boots just fine. Current uptime as of right now is around 29days. There are no messages in /var/log/messages or /var/log/secure about a drive being down, but from the Software RAID howto it looks as if the array is not working correctly. Any diagnostic steps that can be done without taking the machine down, as it is currently a production level machine?
