I started with two 160GB drives in RAID1 using EVMS on Centos 4.4. Both drives have now been replaced with 320GB drives but naturally are only offering 160GB (they were replaced individually at different times and self-recovered as they were RAID1.

I cannot work out how to increase the size of the array to use all the available space on the disk.

If I understand correctly, I should unmount the array, deactivate it and select expand. The problem is that while I can unmount and deactivate it, there is nothing to expand (selecting expand volume, expand storage object and expand container all report no items found). Also, right clicking on the array (in EVMSGUI) doesn't have expand as an option.

The disks are formatted in Ext2/3.

Have I missed something?

I'd rather not replace the old drives, create a second RAID array and copy all the data across as I've a feeling that I'll then have to reset permissions and shares (although I just might get away with then removing the original RAID array and mounting the new one in the same location). In my mind it also ought to be easier to simply re-size the array than have to set up new ones and move the data across. --
