There's no technical reason that should stop you expanding a raid-5 array - do it at work all the time with hardware scsi raid controllers, tho the mdadm might not allow you to do it. I believe some of the broadcom based raid cards allow OCE.
It's also one reason to use LVM on top of raid... add 3 more disks in a new raid array, add it to the volume group, and expand the file system onto te new space.

You can't increase the number of active devices in a RAID-5 (mdadm) array because the distribution of data and parity is set when the array is first created. To increase the capacity of the array you would need to increase the capacity of all of the constituent devices, "grow" the array to take up the extra space and then resize the hosted filesystem. -- "When fascism comes to America, it will be wrapped in the flag and carrying the cross." - Sinclair Lewis (1935) _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
