With regards to your message at 09:05 PM 5/28/03, Maurice Hilarius. Where
you stated:
>Does anyone recognize what is happening here?
Answering my own question:
The machine was built with Red Hat 9.0
At build time it was installed with CURRENT Red Hat kernel 2.4.20-13.9
Then the RAID1 and RAID5 arrays were built with mdadm
My customer decided to re-install Red Hat 9.0, from CD's, but neglected to
install the current kernel RPM updates on to his new server.
It seems that some important md patches have been incorporated into the
newer kernel.
With the new kernel installed it now behaves correctly.
A bit of regression testing reveals that these md devices built with the
older kernel and used with the older kernel work fine.
BUT: If you build them with the newer kernel, then try to run the older
kernel "Bad Things Happen" (tm)
So, live and learn, backwards compatibility may be an issue..
With our best regards,
