Fix my server problem

Hi, Please check this message from the server tech and let me know if you can handle this easily. ------------ It detected problems with the drives. It seems that your raid is degraded: === schnipp === root@rescue ~ # cat /proc/mdstat Personalities : [raid1] md2 : active raid1 sda3[0] 1458830400 blocks [2/1] [U_] md1 : active raid1 sda2[0] 2104448 blocks [2/1] [U_] md0 : active raid1 sda1[0] 4200896 blocks [2/1] [U_] === schnapp === So you should try to start a rebuild. Also there were some ata-Errors in our logs: === schnipp === ata1.00: exception Emask 0x0 SAct 0x3 SErr 0x0 action 0x0 ata1.00: irq_stat 0x40000001 ata1.00: cmd 60/00:00:00:c8:fd/04:00:1f:00:00/40 tag 0 ncq 524288 in ata1.00: status: { DRDY ERR } ata1.00: error: { UNC } ata1.00: cmd 60/00:08:00:cc:fd/04:00:1f:00:00/40 tag 1 ncq 524288 in ata1.00: status: { DRDY ERR } ata1.00: error: { ABRT } ata1.00: configured for UDMA/133 ata1: EH complete ata1.00: exception Emask 0x0 SAct 0x2 SErr 0x0 action 0x0 ata1.00: irq_stat 0x40000008 ata1.00: cmd 60/00:08:00:c8:fd/04:00:1f:00:00/40 tag 1 ncq 524288 in ata1.00: status: { DRDY ERR } ata1.00: error: { UNC } ata1.00: configured for UDMA/133 ata1: EH complete === schnapp === This indicates that your ata1 (sda) needs to be changed. But as the sda is the one drive left in your raid you should first try to backup your data and then rebuild the RAID.
