Hi!
My impression comes from a MySQL AB computer
with Red Hat 6.2 (kernel something like 2.2.19).
There were strange disk read errors. I tracked it down
to a problem where 8 bytes sometimes were reset
to zero at an 8 kB page boundary when the OS
had read a large block of about 300 kB.
Also, just today a large MySQL user reported a
software RAID 'meltdown' with kernel 2.4, I think.
It is encouraging to hear good experiences from
others :).
Regards,
Heikki
