I have created a RAID 10 using a RAID0 configuration on top of a two RAID1 devices (all software raid), like this: Personalities : [raid0] [raid1] md4 : active raid0 md2[0] md3[1] 605071872 blocks 64k chunks md0 : active raid1 sdd3[3] sda3[0] sdc3[2] sdb3[1] 9791552 blocks [4/4] [UUUU] md3 : active raid1 sdd2[2](F) sdb2[0] 302536000 blocks [2/1] [U_] md1 : active raid1 sdd1[3] sda1[0] sdc1[2] sdb1[1] 240832 blocks [4/4] [UUUU] md2 : active raid1 sda2[0] sdc2[1] 302536000 blocks [2/2] [UU] unused devices: But the sdd device sometimes fail, i have changed the hard disk, check the older sata drive, reformat using mke2fs -c -c (to check for media errrors both read and write, no media problems found, change the sata disk and the problem remains, also with a new sata hard disk). The systema is a supermicro server 5015-mt+ with an ich7 ahci controller All SATA hard disk are hitachi, here is a copy of the kernel log: Oct 19 14:01:08 rogue kernel: scsi0 : ahci Oct 19 14:01:08

I am not sure if the problem was because i create the RAID10 using two RAID1 devices and then do a RAID0, or should i have to be used mdadm and the level 10 option ? Any suggestions will be welcome.
