Heloo All, I have fc6 installed on my machine which has a HostRaid enabled adaptec card . And I have connected two SCSI disks to it and configured RAID-0 (Striping). Each conneted disk is of 73 GB When I issue fdisk -l it shows both sda as 73 GB and sdb as 73 Gb. Now my question is how do I access the disk as array? What names should I use to access the raid device. lspci shows this. 03:01.0 RAID bus controller: Adaptec ASC-29320 U320 w/HostRAID (rev 03) 03:01.1 SCSI storage controller: Adaptec ASC-29320 U320 (rev 03) I also tried creating a linux partition on the sda and sdb and created reiserfs file system. But when I try to mount it, the system says "mount: /dev/sda1 already mounted or /disk1 busy" please help me what procedure I should follow to configure the hardware raid in fc6 Thanks -Jag
