"my RAID implementation"? LINUX SOFTWARE RAID and this is how the raid-partitions are looking no problem since years Disk /dev/sda: 2000.4 GB, 2000398934016 bytes, 3907029168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0000ae2c Device Boot Start End Blocks Id System /dev/sda1 * 2048 1026047 512000 fd Linux raid autodetect /dev/sda2 1026048 31746047 15360000 fd Linux raid autodetect /dev/sda3 31746048 3906971647 1937612800 fd Linux raid autodetect [root@srv-rhsoft:/downloads]$ sfdisk -d /dev/sda # partition table of /dev/sda unit: sectors /dev/sda1 : start= 2048, size= 1024000, Id=fd, bootable /dev/sda2 : start= 1026048, size= 30720000, Id=fd /dev/sda3 : start= 31746048, size=3875225600, Id=fd /dev/sda4 : start= 0, size= 0, Id= 0 [root@srv-rhsoft:/downloads]$ parted /dev/sda align-check opt 1 1 aligned [root@srv-rhsoft:/downloads]$ parted /dev/sda align-check opt 2 2 aligned [root@srv-rhsoft:/downloads]$ parted /dev/sda align-check opt 3 3 aligned
