Hello,
We have a server (RHEL4) with 6 750G hard drive and an Intel Raid controller setup as one RAID5 array and partitioned with (1G for /boot - 10G for / and rest (~3.5T) for LVM). I would like to create a LV with 3.5T but the maximum I can create is 1.4T bytes.
Any help or input is greatly appreciated.
Thanks.
