I'm trying to setup a Raid0 using a SCSI LSI Raid controller card and four 9G SCSI drives. The intent is to have two drives (sda and sdb), both of which use Raid0. During POST I can get into the controller bios and set it up for Raid0. I then continue on with the normal boot process, which yields the dmesg attached at the bottom of this email.
I'm trying to make sure I've got this set up correctly and I'm concerned about the following 2 dmesg statements: SCSI device sda: 35094528 512-byte hdwr sectors (17968 MB) SCSI device sdb: 35094528 512-byte hdwr sectors (17968 MB) Is this correct? Since I'm setting this up as Raid0, shouldn't sda and sdb be half that size at 8984MB each? Or is it typical of Raid0 to report the combined size of the two drives it uses for striping? Also, my lsmod shows ... raid0 3104 0 (unused) md 43840 0 [raid0] megaraid 24896 3 (autoclean) Since raid0 is going unused, I take it that I don't need it.
