Soft RAID

Kranti Mahmud — Sun, 11 Jul 2010 10:17:14 GMT

Dear all,

I am having a ML350 G4 with one disk of 146 GB only. At present this server is using as a business critical node. I like to add one more disk on it and want to make an soft raid/mirror for the disk availability. Is it possible to add another disk with the existing disk and soft mirrored them without any kind of data modification or alteration?

You will have to modify a few things:

Hi Alexander,

Thanx for your reply. Please cpnfirm me one thing, does this procedure confirms that there will be no data loss as my node is a business critical node?

Secondly, what are the other precautions we can take before these activities?

Hi Kranti.

One thing you will have to do (and it answers the second question) - backup all the important information prior "playing" with the system.

If you follow the instruction and make no confusion between the source and the destination - there should be no data loss.
