Add disc to RAID5 and extend 1 partition to use that space.
We are running RedHat 8 on a Compaq Server with 3 SCSI drives connected to the smartarray5i (RAID5) controller.
As we need more space on the /usr/data partition we want to add a fourth drive to the array.
Filesystem Size Used Free Used Mount
/dev/cciss/c0d0p5 4.8G 1.9G 2.7G 41% /
/dev/cciss/c0d0p1 73M 9.6M 59M 14% /boot
none 503M 0 503M 0% /dev/shm
/dev/cciss/c0d0p6 3.8G 849M 2.8G 23% /usr/mainapp
/dev/cciss/c0d0p7 23G 3.1G 18G 91% /usr/data
/dev/cdrom 652M 653M 0 100% /mnt/cdrom
/dev/cdrom 652M 653M 0 100% /mycd
How do I start? What happens if I just insert the new disc?
Many thanks in advance!
