I think you can only select RAID mode at initial installation, and it cannot be changed later.
Your alternatives are:
1) do a full system backup, then install a larger drive, then reinstall sme OS, then restore from backup and install any contribs. The standard backup tool or other contribs will do this OK for you depending on how much data you have.
2) Temporarily remove the existing drive, install the larger drive, install the sme OS, re-attach the old drive and do a restore from disk using the techniques outlined in
http://wiki.contribs.org/UpgradeDiskYou will still need to reinstall any contribs.
3) You could copy ibay data off the server, then do a configuration backup using the techniques in
http://wiki.contribs.org/Backup_server_configRebuild a new server with a larger hard drive or drives, restore the backup, then reinstall contribs, then copy back the ibay data
4) Use Affa to backup and rebuild a new server see

http://wiki.contribs.org/Moving_SME_to_new_HardwareYou will still need to reinstall contribs
For the future, it's always a good idea to configure all servers using RAID1, even where a single drive is installed.
That way it's easy to add a second drive later, and use other techniques to upgrade disk size etc .
sme will run with a single drive in degraded RAID mode quite OK.
...after I upgraded the server to the latest software, I found out that there were a whole bunch of output errors in the /var/log/messeges and /var/log/lastlog and mysql gave me error 28 (out of space ) , and my mamboo site failed.
You obviously have some other issues, perhaps related to mysql.
You really need to quote the errors, but please start a new thread.
