RAID problem

I running my B3 with RAID via eSata disk. The last day I got error message:

"RAID Array degraded
The array /dev/md0 is degraded"

Anyone know what the problem could be? What I can see the disk seems to be ok.

even a small hiccup in the connection can create this inconsistency. Let it rebuild en keep an eye on it. These things happen. They just should not happen too often :D

At the moment this happens once a day and I don't think it's normal?

I guess it rebuilds to full between those messages? It does sound suspicious. Can you show the data in in /proc/mdstat when the raid is degraded?

Next step will be having a look at the SMART results. Theres a lot of info on that in other threads.

The data in /proc/mdstat are:

Personalities : [raid0] [raid1]
md0 : active raid1 sda2[0]
1941979072 blocks [2/1] [U_]

I guess you're right. In my limited knowledge I'd say either the disk is borked or the cable is flaky. If it's still in warranty you may want to submit a message to Excito.
