ext3-fs error with RAID 5 Array.

[Jan Stobbe]

Hi Kannan,

we had similar problems with ext3. After a month of searching for the
error we changed the mainboard of the server. The maiboard was to old to
work properly with the new areca raid controler we used.
Without heavy load the device was o.k.


Best regards, Jan
