Dear Gary, Thanks for really good information. We had tried AoE with these scenarios:
We used 80GB HDD with CentOS-5 installed. We are successful to export a partition to other system, It is really good and fast. Now We had tried with Adaptec SAS RAID Controller, Here we had some issues. When weinstalled CentOS- on the RAID and configured AoE, We are successful to export a partition to other systems. But, when we had seperate HDD for OS and tried to export the RAID disk or partiton, It is not been exported to other systems. we haven't found any error messages in /var/log/messages. but the output of "#aoecfg" command is showing the specified major ,minor numbers of the exported RAID disk. host/#aoecfg 8.2 8.17 Where 8.2 is one of our OS disk partition, which can be mounted. But, 8.17 which is RAID disk partition, which we can't able to find neither "#fdisk -l " nor in /dev/etherd/ Please help us.
