Hi, Sorry for spamming the list so hard... Now I'm missing something. I issued the following commands in the Lenny installer:
~ # modprobe raid1 ~ # mdadm --create /dev/md0 --auto=yes -l1 -n2 /dev/ram0 /dev/ram1 mdadm: array /dev/md0 started. ~ # cat /proc/mdstat Personalities : [raid1] md0 : active raid1 ram1[1] ram0[0] 8128 blocks [2/2] [UU] After this partman presents me with the following menu items: 6. RAID1 device #0 - 8.3 MB Software RAID device 7. > #1 4.2 MB What are those two different sizes? ~ # parted_devices /dev/md0 4161536 Unknown ~ # mdadm -D /dev/md0 /dev/md0: Version : 00.90.03 Creation Time : Sun Apr 6 22:41:37 2008 Raid Level : raid1 Array Size : 8128 (7.94 MiB 8.32 MB) Used Dev Size : 8128 (7.94 MiB 8.32 MB) Raid Devices : 2 Total Devices : 2 Preferred Minor : 0 Persistence : Superblock is persistent Update Time : Sun Apr 6 22:41:40 2008 State : clean Active Devices : 2 Working Devices : 2 Failed Devices : 0 Spare Devices : 0 UUID : 943b966d:1f04bc87:b8bc6804:7db3c3dc Events : 0.2 Number Major Minor RaidDevice State 0 1 0 0 active sync /dev/ram0 1 1 1 1 active sync /dev/ram1 ~ # lsmod Module Size Used by raid1 21984 1 md_mod 71316 1 raid1 xfs 476760 0 I would be grateful if somebody could provide an explanation. -- Thanks, Feri.
