Change array from raid 1 to raid 5

hello,

have an ML330 using the 641 controller with two 72GB drive in raid 1. They are out of space and I need to add additional drives. Want to break the mirror, add the 2 additional drive and create a raid5 array with the 3 drives leaving the first drive from the mirror intack. Anyone done this before? can this be done without data loss?

Re: Change array from raid 1 to raid 5

no way to "break" the mirror in the way you desire.

you can arrive at the same ending point from different ways.

let me know if you are interested.

bye.

What are my options?

Re: Change array from raid 1 to raid 5

one of this is to use the "on-line-level-migration" feature of your controller to migrate from raid 1 to raid 5.

after of that yu can create your own "disk clone".

How many points should I assign to replies?
Every response to your question is eligible to earn between 1-10 points. No need to worry about running out of points - when a truly awesome reply rolls in that deserves a 10, you will be able to assign it a 10! However, be careful to assign points based on the value that a reply truly provides. Use the following scale as a guideline:



o N/A: The answer was simply a point of clarification to my original question

o 1-3: The answer didn't really help answer my question, but thanks for your assistance!

o 4- 7: The answer helped with a portion of my question, but I still need some additional help!

o 8-10: The answer has solved my problem completely! Now I'm a happy camper!


Although assigning points is not mandatory, it is a key component of a strong, interactive community, and it is STRONGLY ENCOURAGED. Others have taken time to help you, so please take a moment to give them credit for their assistance!
