Try "mount -oro /dev/sda /mnt/tmp" (or whatever) or just see if there's
a
superblock there with "tune2fs -l /dev/sda".
he has a hardware raid set of drives originally from a HP/Compaq SmartArray controller, now connected to a simple non-raid scsi controller. sorry, thats not gonna play no way no how.
Since he only mentioned one device on his centos, there are centainly plausible ways this could work. The original cciss array could have been a single drive, could have been a raid1, could have been a misunderstood
hwraid
just tunneled through the host adapter as a single driver, etc.
. The SmartArray doesn't recognize the external array. So thats why I connected it to a SCSI non-raid controller which does. lvndiskscan on my Centos server even can tell the size of it. /dev/sda [ 2.00 TB] The external array has it's own built in raid controller. The Bios the SmartArray said it was a raid 0 2048GB failed. I not sure why the SmartArray sees it as that because the external array is configured as a raid 5 with spares. Im not familar with the SmartArray and don't have another to try.
Is there no way to access the data other than via the SmartArray?
The smartarray sees it as a raid0 with one drive because that is how its bios works. If you attached a single scsi drive to it, you could set it as a single drive and it would show up as a raid0 stripe with one drive.
