Well I installed by fresh copy of ubuntu last night, partitioned by disks, and started the raid setup and went to bed. Woke up this morning and found that it had encountered some errors in a drive sda in this case and had booted it out. Cool, doesn't worry me, glad I found it now rather than later.
I've just got a couple of questions i've not been able to find the answer too.
Firstly, How come the Used Dev Size is 3000 GB. My friends arrays, the size is = too the size of one hdd.
Version : 01.02
Creation Time : Tue Jul 13 20:44:41 2010

4 8 81 4 active sync /dev/sdf1
5 8 97 5 active sync /dev/sdg1
6 8 113 6 active sync /dev/sdh1
Secondly, Events 1038. The Number of events seems to increase quite quickly. I've got it emailing me, but I've only received 2-3 emails about the degraded array status. What are the other evens likely to be, and is there a way to check them?
And thirdly, it thinks the version is 01.02 Is that a problem? Shouldn't it be 1.2?
Otherwise its going well. Getting 150 MB/s writes and 420 MB/s Reads while degraded.
7x 1.5 TB Samsung F2 Eco Green, and 1x 1tb Samsung F1 Os drive.
Thanks for your help!
