Fake raids are, well, fake. The kernel sees both > individual disks and since they are mirror images of each other, both have > the same partitions on them. >=20 > The dmraid utility can be used to recognize the fake raid metadata and > configure the kernel device mapper to access the raid, and with the -Z > switch, it will remove the partitions from the underlying individual disks > from the kernel's view. dmraid is not used; mdadm is used ******************** cat /proc/mdstat -------- Personalities : [raid1] [raid6] [raid5] [raid4]=20 md125 : active raid5 sdh1[4] sdb1[2] sdi1[6] sda1[0] sdc1[1] sdf1[3] 87890972160 blocks super 1.2 level 5, 512k chunk, algorithm 2 [6/6] [UUUUUU] bitmap: 5/131 pages [20KB], 65536KB chunk md126 : active raid1 sde[1] sdd[0] 975585280 blocks super external:/md127/0 [2/2] [UU] md127 : inactive sde[1](S) sdd[0](S) 2354608 blocks super external:ddf unused devices: --=20 You may reply to this email to add a comment.
