Here I found it "man md" :
UNCLEAN SHUTDOWN
......
To handle this situation, the md driver marks an array as
"dirty"
before writing any data to it, and marks it as "clean" when the
array
is being disabled, e.g. at shutdown. If the md driver finds an
array
to be dirty at startup, it proceeds to correct any possibly
inconsis-
tency. For RAID1, this involves copying the contents of the
first
drive onto all other drives. For RAID4 or RAID5 this involves
recalcu-
lating the parity for each stripe and making sure that the parity
block
has the correct data. This process, known as
"resynchronising" or
"resync" is performed in the background. The array can still be
used,
though possibly with reduced performance.
...
That is intresting because I can not shutdown/reboot my machine in a
normal way (Kernel: 2.4.21-9.0.1.EL.um.3smp, I have to use the reset
button!!).
The resynchronising is running in the background after starting the
system and finshed after approx. 1 Hour. but the state does not change.
