Hello all,
I have one question (maybe noob) about partitions on my DNS323. I'm using RAID0 configuration, but as long as disks are not identical size also I have JBOD partition. So two partitions: RAID0 and JBOD. We all know that these is:
sda1 sdb1
sda2 sdb2
sda3 sdb3
sda4 sdb4
So I have folowing questions:
1. sda1 and sdb1 is linux swap partition. How should I treat it? Like separate disks sda1 and sdb1 or like RAID sd[ab]1 ?
2. sd[ab]2 is my main RAID 0 partinion and sda4, sdb4 is JBOD. How should I treat JBOD partition like RAID (sd[ab]4) ?
3. What is sda3 and sdb3 ? I get an error when using e2fsck. It says that partition size differs from physical size. Ok, I know how to deal with this error (at least I can find some info on it), but what is sda3 and sdb3 in general. What partition it represents ?

Actually, you have it incorrect. Partitions 1 are indeed swap, and they are individual to the disks. swapon and swapoff are the commands used with these.
Partitions 2 are for your RAID 0 (I STRONGLY reccommend you get rid of this, as you are just asking to lose all your data, and there is 0 benefit to RAID 0 on the DNS). All activities for these (assuming the array is intact) are handled via the Multiple Devices driver (md0, md1, etc.).
Partitions 3 are you JBOD and you would need to do e2fsck on the multiple device (md1) virtual partition the same as you would for your RAID0 (md0).
Partitions 4 are configuration partitions that are also individual to the disks. Do not mess with these unless you know what you are doing, as make a change can cause the DNS to want to format and start over.

Hi,
Thanks for answering. I got it and will do upgrade to 1.5TB disks and do not use RAID0 anymore. Its seems that I have problem with my JBOD partition... I think I'll wait until upgrade because I'm affraid of loosing my data as you said.
Its very nice that you helped me with this. Thanks again.
