I just went to bed and one last question popped in to my mind. Since there is a fair timezone gap I thought I'd be presumptuous and ask it in the hope I can turn it around a bit quicker in the morning. My suspicion is that once I have 5 formatted 2tb drives I may be lucky to get 10x 1tb dd images on to it. Can I feed the dd process in to tar, bzip2, zip or something else which will give me enough space to fit the images on ? Will I get more usable space from 5x2tb partitions or from 1xspanned volume ? (the thecus pretty much only allows you to create raid volumes so a jbod needs to be 5x1tb arrays or 1 spanned volume or stripe).

I wiped out the existing raid5 array to create a jbod span of 10tb in order to hold my 9tb of backups. The Thecus has had a hissy fit and I've had to set the process off again, so you can bet it'll be a day or two before it get's the drives formatted (it's not a very powerful nas), then I'll do the backups, then I'll try as you suggested. > > That's fine. >> >> Thanks for the ongoing assistance. > > No problem. > > Phil -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
