| Tools that manage md devices can be found at |
| http://www.<country>.kernel.org/pub/linux/daemons/raid/.... |
| |

| |
| You can boot (if you selected boot support in the configuration) with your md |
| device with the following kernel command lines: |
| |
| for old raid arrays without persistent superblocks: |
| md=<md device no.>,<raid level>,<chunk size factor>,<fault level>,dev0,dev1,...,devn |
| |
| for raid arrays with persistant superblocks |
| md=<md device no.>,dev0,dev1,...,devn |
| |
| md device no. = the number of the md device ... |
| 0 means md0, |
| 1 md1, |
| 2 md2, |
| 3 md3, |
| 4 md4 |
| |
| raid level = -1 linear mode |
| 0 striped mode |
| other modes are only supported with persistant super blocks |
| |
| chunk size factor = (raid-0 and raid-1 only) |
| Set the chunk size as 4k << n. |
| |
| fault level = totally ignored |
| |
| dev0-devn: e.g. /dev/hda1,/dev/hdc1,/dev/sda1,/dev/sdb1 |
| |
| A possible loadlin line (Harald Hoyer <HarryH@Royal.Net>) looks like this: |
| |
| e:\loadlin\loadlin e:\zimage root=/dev/md0 md=0,0,4,0,/dev/hdb2,/dev/hdc3 ro |
