Hi, I have a Fujitsu Siemens Primergy RX200 with Fedora Core 3 installed (Kernel 2.6.12-1.1381_FC3smp). The machine is equipped with the following SCSI devices: Attached devices: Host: scsi0 Channel: 00 Id: 08 Lun: 00 Vendor: SDR Model: GEM318P Rev: 1 Type: Processor ANSI SCSI revision: 02 Host: scsi0 Channel: 01 Id: 00 Lun: 00 Vendor: MegaRAID Model: LD0 RAID1 34700R Rev: 1F34 Type: Direct-Access ANSI SCSI revision: 02 I have installed 2 HDs with RAID 1 and it seems to work well. My question is: how can I know if one disk fails? Is there something link /proc/mdstat ? Alternatively: if one disk fail any message will be written to the log files? Thank you very much for your support!
