some how /dev/hdc2 is not being used by the system i think... i just want /dev/hdc2 to be an extended space for an i-bay.

wires..

as you can read in the documentation, if you install SME with 2 hd connected you get the raid1 option enabled by default..

that said, you have 2 different hd and thus your bigger one is used only a bit..

anyway, I see your raid has some problems.

can you confirm that the 2 hd were connected when you setup SME?

yes i confirm, i installed sme server with 2 disk connected, meaning the 2nd disk was already installed inside the computer when i got sme server installed on the system.

cheers

if so both disks are part of raid1 array..

but I see it's not working, it's in degraded mode.. and from here:

Code: [Select]

    Personalities : [raid1]
    md3 : active raid1 hdc1[0] hdc2[1]
          104320 blocks [2/2] [UU]

    md2 : active raid1 hda2[0]
          38973568 blocks [2/1] [U_]

    md1 : active raid1 hda1[0]
          104320 blocks [2/1] [U_]

    unused devices: <none>



I see also there's something messed up.

please raise a bug.
