I managed to mess up a RAID-5 array by mdadm -adding a few failed disks back, trying to get the array running again. Unfortunately, -add didn't do what I expected, but instead made spares out of the failed disks. The disks failed due to loose SATA cabling and the data inside should be fairly

Dear All, I have an 8-drive raid-5 array running under 2.6.11. This morning it bombed out, and when I brought it up again, two drives had incorrect event counts: sda1: 0.8258715 sdb1: 0.8258715 sdc1: 0.8258715 sdd1: 0.8258715 sde1: 0.8258715 sdf1: 0.8258715 sdg1: 0.8258708 sdh1: 0.8258716
