Hi All,
I have a linux machine which is a backup server and is running out of space.

this has 2 hard disks (phisical volumes... sda and sdb), please see output of fdisk command below:

[root@support /]# fdisk -l

Disk /dev/sda: 254 heads, 63 sectors, 2221 cylinders
Units = cylinders of 16002 * 512 bytes

I want to create new partitions but the problem is that i have run out of space on the disk. (i get the error no free sectors available).

I physically added a new harddisk of 34 gb into the raid array and ran the IBMs serveraid tool. When i rebooted my machine, i dont see any additional space in the existing partitions, nor do i see any new phisical volumes like /dev/sdc in the fdisk output (the output above is the one i got after a reboot).

Is there some configuration i need to do on the linux side inorder to start using the new disk? Please advice.

I also am encountering this problem. Since nobody replied it is probably a quick fix but any clues would be helpful!

Hi,

I'm totally unfamiliar with your hardware, and I don't know the serveraid program. But...

- When adding a new disk, I would not expect new space to appear in raid arrays. I think LVM needs to be used for that
- I'm a bit confused about the raid part too. You say you have two physical disks. fdisk -l lists two disks. I'm not sure if you even have raid.
- I would expect a new physical volume (/dev/sdc or somesuch) to appear
- fdisk -l isn't showing all disks on my system either, I don't know why
- Apparently, fdisk -l consults /proc/partitions, which correctly lists all my disks. Try
- Alternatively, try
and try to locate the kernel messages that detect the disc. Search for sda for example. My log says:
Oh.... Reading manpages usually provides quick hints (like /proc/partitions, above). Very usefull, especally in case of urgent questions.

Groetjes,

Kees-Jan

Since LVM is not configured or running - I guess I will use Parted to move and expand the current partitions as it seems like the best tool to use for the situation, but check out my hdd partition info below as it seems to create more questions than it answers :-0 . BTW, if anyone has a better way to skin this cat, please let me know. Below is my disk info.

This machine is an IBM x226 running RHES and was loaded by IBM. It came with 1GB of RAM but they only have it about 500MB's of swap and only a couple of hundered MB for /var (that would complicate any serious logging). Also, are those Win95 partitions needed for the serveraid? The linux partitions are within these Win95 partitions. I've never seen this before.
I added the 2 250GB hdd's and extended the RAID with IBM's serveraid. I thought it would extend it's own volume but it only did the physycal part and left me to mess with the partitions (oh yay).
