Hi,

after our server crashed on Friday and Sunday, we can see some strange raid 
related messages in the logs (please see the messages below).

Well, the 'delaying resync ...' messages are easy to understand, but are they 
related to the 'resync aborted' messages ? At least the /proc/mdstat looks 
fine.

The bzip2-output of dmesg (that might give more information about what is 
going on) is attached.


So do we have do worry about something going wrong with the software raid ? 

Of course, we are a bit worried about the the crashes at all, since this never 
happend before.


Thanks in advance,

Bernd


PS: The kernel is a vanilla 2.4.19 with some of Neils NFS-patches that went 
into 2.4.20pre1 (all except the tcp-patches).
