I've assembled software raid1
/dev/md1, and made two partitions
/dev/md1p2. Now even after reboot I can't see these two in
Why? (udev service is running)
#fdisk /dev/md1 Command (m for help): p Disk /dev/md1: 2000.3 GB, 2000346808320 bytes 2 heads, 4 sectors/track, 488365920 cylinders Units = cylinders of 8 * 512 = 4096 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/md1p1 1 9765625 39062498 8e Linux LVM /dev/md1p2 9765626 488365920 1914401180 8e Linux LVM
