(using /dev/dm-* for filesystem volumes) # lspci | grep -i sata 03:05.0 RAID bus controller: Silicon Image, Inc. SiI 3114 [SATALink/SATARaid] Serial ATA Controller (rev 02) # df -m Filesystem 1M-blocks Used Available Use% Mounted on /dev/dm-6 125931 2999 116432 3% / /dev/dm-1 99 13 81 14% /boot tmpfs 1012 0 1012 0% /dev/shm /dev/dm-2 9917 151 9254 2% /tmp /dev/dm-3 9917 237 9168 3% /var # lsmod | grep ata sata_sil 13897 2 libata 58321 1 sata_sil scsi_mod 129641 3 sg,libata,sd_mod # cat /etc/modprobe.conf | tail -n 1 alias scsi_hostadapter sata_sil So in fact /dev/dm-* are just on one disk each (not RAID1), or what is going on here? -- Florin Andrei http://florin.myip.org/
