linux raw and quorum partition
i create new partition:
Primary
/dev/sdb1 20GB
/dev/sdb2 20GB
/dev/sdb3 20GB
Extended
/dev/sdb5 40GB
Refer from kimberlite cluster manager(missioncriticallinux.com)
i need to create shared quorum partitions using RAW
what i did:
raw /dev/raw/raw1 /dev/sdb1
raw /dev/raw/raw2 /dev/sdb1
[root@clu1 share2]# raw -qa
/dev/raw/raw1: bound to major 8, minor 17
/dev/raw/raw2: bound to major 8, minor 17
My question is:
1)what is raw,
2)do i need to re-partition everthing, create 10MB partition for raw1 and another 10MB for raw2,
DOC:maximize performance by using raw I/O. One may use the raw command for both IDE and SCSI devices. This will map a raw device to a blocked device for an entire disk partition
3)i still cannot understand what the DOC say.
