I had a powerloss during the night. In the morning I tried to boot the server (last updates), no luck. The server has to sata-drives, they are hardware- and! software-mirrored.
I disconnected the drives from the board and tried to boot the server from the install-cd - no luck. I erased the bios-settings, tried the same again. Worked.
I plugged the two harddrives on the board. The machine was booting. Got following messages:

The hardware monitor (while booting the machine) tells me, the two disks are in sync and healthy.
Next, I checked the following:

O.K., I decided the start the mirroring from the console. The result now is:

So far so good, everything is looking fine. I decided to reboot the machine. Was not able to boot again: Got a Grub error.
Grub loading Stage 1.5
The machine hangs.
After changing the two drive-connections on the board, I got an error from the board, that the RAID is NOT in sync. But I was able to boot the server without any problems.
I decided to boot the machine again - got the same result. Fixed it in the same way as a.m.
This error occurs since the last update (the system was always up to date). Before I had never a problem to reboot. The configuration was the same, no changes at all.
A few weeks ago, I had a similar problem that ended in buying a new server. One of the disks crashed - I was not able to boot from the other disk. Everything endet in a GRUB errot. The setup of the machine was a RAID1 (two identical disks). There was no mirroring on board, only softraid.
I have no idea, where the reason could be - any hints are welcome.
Bug 3029 opened.
