We have an HP ML 350 G6 with an HP smartArray 410i controller. Running Ubuntu x64.
We previously had 8 146G drives configured as a 820GB raid 50 logical drive.
Now I have replaced 4 146GB drives with 900GB drives and want to resize the logical drive.
But for some reason that doesn't work. hpacucli gives the following error:
ctrl slot=0 ld 1 modify size=max Error: This operation is not supported with the current configuration. Use the "show" command on devices to show additional details about the configuration.
I assumed that one could have two parity groups with different size, because they are independent. What is the best way to migrate to utilize the full disk size ? How can I reconfigure without losing data ?
My configuration is as follows:
