Question raid 0 concern --adding new hdd


/dev/sda------68.3GB----ST373207LC FN-------------------0----------8923-----
/dev/sda1-----400MB----LINUX NATIVE---------/BOOT----0----------50--------
/dev/sda2-----2.0GB-----LINUX SWAP----------SWAP------51--------312------
/dev/sda3-----65.9GB----LINUX RAID----------------------313-------8922------/dev/md0
/dev/sdb1-----68.3GB----LINUX RAID----------------------0----------8922-----/dev/md0
/dev/md0-----134GB-----MD Raid------------------/------- - - - -

I have another scsi hdd 73GB. I want it to add to my existing Raid 0 based on the above config. Unfortunately I dont know how. Based on my research, If I want to add another hdd to the existing raid, all hdd will be formatted. Correct me if Im wrong.I dont want to do that, I just want to add my extra hdd to the existing Raid, which is raid0.

What you want is (naturally) not possible.
You will have to save the existing data somewhere,
then do the RAID0 expansion and finally copy your data back.
No way to do the RAID0 expansion in place.

Have fun!
