I have a server that has 4 1.5 TB disks. Every disk has identical partitions
- /dev/sd[abcd]1 200 MB
- /dev/sd[abcd]2 2 GB
- /dev/sd[abcd]3 1.5 TB (the rest of the disk)
/dev/sd[abcd]1 are RAID 1 device with four disks and it's mounted to the /boot partition. md3
/dev/sd[ab]2 /dev/sd[cd]2 are two different RAID 1 devices and both are swap partitions. md1 md2
/dev/sd[abcd]3 are RAID 10 device and it's the root(/) partition. md0
There is no installed LVM on top of them.
Now, I need to create a new 150 MB partition from md0 device. I have no direct access to the server but I may find a KVM, but it is not preferable as I have to use a terrible KVM device :) The server is newly formatted so the last option is to reinstall the system with the intended partitions and LVM on top of them to reduce future problems, but as I said I don't prefer to use it, since it will take 6-7 hours to install a new server. (and I have two identical servers)
What are my options?
- Reinstall the server
- Boot from CD and install LVM.
Thanks in advance,
