Thanks for the advice. I tried again today. The size of the via_cdjiceidbi file is 0. The message in /var/log/messages is: localhost kernel: device-mapper: error adding target to table Besides, the dmraid -v via command reports a wrong size, 240121727 for two 120MB drives in mirroring mode. I can use the array without any problems in Windows. Not being able to use it is the last obstacle to a complete switch to Linux...but what can I do? Trying to configuring the device mapper manually seems too risky to me.
