Olaf, the block address, volume number and block number, is a single 32 bit value. In the default configuration we have 8 bits reserved for the volume number and the remaining 24 bits for the block number. So we have a maximum default volume size of 2^24 * 8Kb = 128GB. You can reduce the VOLUMENO_BIT_COUNT parameter to increase the maximum volume size. E.g. set it to '7' and double the max. volume size to 256GB. And as Markus Döhr states, you'll get a higher I/O performance with multiple volumes. henrik -- MaxDB Discussion Mailing List For list archives: http://lists.mysql.com/maxdb To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
