Hello,

we own an areca 1210 and currently have a RAID5 with 4x250GB. As disk space
is low we'd like to replace it with 4x1000GB.

We already found a supported disk, hotpluggable, etc.

Now after subsequently replacing the drives how can we expand the RAID set
to a net of 3TB (the controller does support sets that large). I scanned
the manual and FAQ at areca but couldn't find any pointer on how we would
go about that.

Anyone been there done that?

thank
martin

Whatever you decide to do...

Do a full backup first!

Seriously, rent a tape drive for the duration of the process if you
have to, but don't try to wing-it without a backup.

Been there done that. Since that (not so amusing) memory I do have cyclic
backups with the option to trigger it whenever needed (like now)

To answer myself and for the reference of someone else:

You need to update the firmware to at least: V1.43 2007-4-17

Then get the archttp from the areca site (get the newest!)

after that you can "RESETCAPACITY Raid Set # 00" enter in the
"Rescue Raid Set" screen. It will recognise the new sizes.

Proceed as normal (add VolumeSets, expand a volumeset whatever...)

hope it saves someone some time...
