Hi there,

I just created a software raid1 array with mdadm on my Ubuntu 6.10 box.
It works fine so far, but during boot, my system spends about 8 minutes without progress after displaying "md: raid1 personality registered for level 1" (see the dmesg log below). This is about the time the raid array needed to sync after creating, so maybe it is resyncing every time on boot - not in the background as posted by other people but obviously in the foreground.

Is there any way to prevent this resyncing or whatever causes this 8 minutes delay?

Before shutdown, I checked the md0 array by means of /proc/mdstat, showing no sign of syncing. Hence, there should be no necessity to resync.

Here is the relevant dmesg output:
[17179578.988000] md: md driver 0.90.3 MAX_MD_DEVS=256, MD_SB_DISKS=27
[17179578.988000] md: bitmap version 4.39

[17180092.712000] md: md0 stopped.

[17180092.740000] created bitmap (153 pages) for device md0
[17180093.252000] Attempting manual resume

Many thanks,

Hi again,

due to my insufficient knowledge of md, I was rather on the wrong track...

The problem was in fact a wrong UUID in the mdadm.conf file of the initrd image.

The solution is very well described in the thread "Software RAID and Upgrade from 6.06 to 6.10" at ubuntuforums.org - many thanks to the guys there!
