The ramdisk image contains the drivers that are available at boot time. If you
are not booting off of that array, then modules in the OS build should be
available, and should be queried and/or loaded to activate that device based on
the OSes and module management boot sequences.
If you open a shell window, what does the following command produce?
dmesg | grep 'sd[a-z]'
If you want to go with LVM, I can provide you assistance in doing that, it is
really not hard. Before using the below
script, post your output back here and lets make sure we understand which disks
are being recognized/used for which function.
Basically, it goes like this:
for each disk in the array, do something like the following, where DISK_CHAR is
one of the letters (besides 'a' if that is your boot drive)
Put this text into a file named makearray, and then you can do
sh makearray b c d e
for example, to make an LVM array out of those disks, striped, with out any
error recovery. Pay attention to which device letters you are using here, and
note that this script provides defaults if you don't provide any arguments!
I crafted this just now, but it should work for 6 scsi resolved SATA/SCSI disks
beyond the first disk (the /dev/sda) disk.
#!/bin/bash
lst=
drives=${*:-"b c d e f g"}
for DISK_CHAR in ${drives}
do
lvm pvcreate /dev/sd${DISK_CHAR}
lst="${lst} /dev/sd${DISK_CHAR}"
done
# with all the drive names for the volume group
lvm vgcreate vg_riven_store ${lst}
# now create the mountable volume
lvm lvcreate --name lv_varsnd --size NNNNg vg_riven_store
with these commands you'll get an array. However, if you lose one disk, the
whole pool is gone. As was suggested, using ZFS would be a better choice, even
if you just build ZFS for your centos appliance, and then create your snd pool
with it instead.
