I have RAID5 on a Dell PE2400. There is no doubt it's RAID since I put the disks in and formatted the array. So I am pretty sure :) This is a fairly old machine and FreeBSD does not support the controller in that to do any kind of repairs/changes to the array must be done via the BIOS. ______________ The dmesg: atapci0: port 0xfc00-0xfc0f,0x376,0x170-0x177,0x3f6,0x1f0-0x1f7 at device 31.1 on pci0 ata0: channel #0 on atapci0 ata1: channel #1 on atapci0 atapci1: port 0xbc60-0xbc6f,0xbc78-0xbc7b,0xbc80-0xbc87,0xbc90-0xbc93,0xbc 98-0xbc9f irq 20 at device 31.2 on pci0 ata2: channel #0 on atapci1 ata3: channel #1 on atapci1 : ad4: 76293MB [155009/16/63] at ata2-master UDMA33 Mounting root from ufs:/dev/ad4s3a _______________ df Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/ad4s3a 507630 58900 408120 13% / devfs 1 1 0 100% /dev /dev/ad4s3g 61419970 44879206 11627168 79% /home /dev/ad4s3e 507630 70 466950 0% /tmp /dev/ad4s3f 6090094 1807368 3795520 32% /usr /dev/ad4s3d 3045006 1431302 1370104 51% /var That said it works perfectly (if invisibly). I have had single disk failures over the years and happily raid'ed on until I could swap out the disk and rebuild the array. Unfortunately the only thing hot about the swap was my blood pressure. So the answer is you can not tell that its not RAID. If you have a remote console and can see the BIOS messages on a reboot - that should clear it up I hope this helps
