I have a FreeBSD 4.9 machine (i386) with 3 hard drives in it. I
installed a 4th hard drive and booted the system however this changed
the drive numbers (expected since I rearranged their connection order)
and fstab refered to the wrong drives so the only drive that was able
to be mounted was the root drive. [see the end of the message for
dmesg output, fdisk output, and fstab info]
I looked at my dmesg output and figured out the mapping between the
old drive numbers and the new numbers and tried issueing the command:
mount -t ufs /dev/ad5s1c /mnt
(this drive used to be ad6 but is now ad5, fstab reads /dev/ad6s1c)
and instead of mounting the hard drive on /mnt I get the following error:
mount: /dev/ad5s1c: Device not configured
So I thought maybe I am confused and this drive is not ad5, maybe its
ad6 or ad7... So I tried the same mount command and got:
mount: /dev/ad6s1c: Operation not permitted
mount: /dev/ad7s1c: Operation not permitted
(Either ad5 or ad6 is blank, it is hard for me to tell for sure since
they are both the same model of hard drive however I am pretty sure
its ad6 that is blank. ad5 and ad7 were both mountable before
installing the new hard drive).
Next I tried:
cd /dev
rm ad5* ad6* ad7*
sh MAKEDEV ad5 ad6 ad7
and then tried mounting the drives as described above with the same results.
At this point I am not sure what to do. Can someone point me in the
right direction?
Here is my hardware configuration:
Computer:
k6-3 400mghz
296mb of ram
HighPoint HPT370 Raid Controller (motherboard doesn't support ata100
drives so I have a pci card that all the drives plug into)
ide connection:
all drives are set to cable select and connected to the raid
controller card via two cables (so on each channel there is a master
and a slave).
here is some output from dmesg:
atapci1: port 0xb800-0xb8ff,0xb400-0xb403,0
xb000-0xb007,0xac00-0xac03,0xa800-0xa807 irq 10 at device 9.0 on pci0
ata2: at 0xa800 on atapci1
ata3: at 0xb000 on atapci1
[...]
ad4: 156334MB [317632/16/63] at ata2-master UDMA100
ad5: 190782MB [387621/16/63] at ata2-slave UDMA100
ad6: 190782MB [387621/16/63] at ata3-master UDMA100
ad7: 76319MB [155061/16/63] at ata3-slave UDMA100
Mounting root from ufs:/dev/ad4s2a
ad4 = root hard drive
ad5 = old ad6
ad6 = blank hard drive
ad7 = old ad5
It is possible that I have ad5 and ad6 confused since they are the
same model of drive however I am pretty sure ad6 is the blank one.
Now for some fdisk output:
