raid or not raid

[kalin mintchev]

hi all..

i have a box in a remote hosting facility that claims that the machine has
two discs raided in it but df and fstab show only one disc with a bunch of
slices.
under devices there is another name - ad6 - but it's not mounted anywhere.
the one i see both in df and the fstab is ad4 with one big slice and
different partitions....

they insist there are 2 raided discs in tha machine. the os is 5.4 and i
think at that point the raid drivers were still considered 'experimental'.

it makes sense to me that if i don't see a second drive in the fstab there
isn;t any mounting which means that there is no raid going on...

is there any other way i can make sure if raid is actually on?
would there will be any logs somewhere?
the machine has been up for about 2 years and the dmesg is long gone...

thanks.....
