Hi all, I have applied the patches required for device mapper from device-mapper-latest.tgz, and then went on to use to ioctl interface ( I ran devmap_mknod.sh script) ... I could not make out as to what the difference will be if I use the devfs ... But the change I can see if this : Earlier my partitions were being represented as /dev/hda1, /dev/hda2 ... and /dev/hdb1, /dev/hdb2 .... The current representation is like this : [root@volts root]# /dev/discs/disc disc0 disc1 [root@volts root]# ls /dev/discs/disc0/ disc part1 part2 part3 part4 part5 part6 part7 [root@volts root]# ls /dev/discs/disc1/ disc part1 part2 part5 part6 part7 part8 [root@volts root]# ls /dev/discs/disc1/ disc part1 part2 part5 part6 part7 part8 [root@volts root]# and there is no entry for /dev/hda or /dev/hdb ... as is evident in the following lines : [root@volts root]# fdisk /dev/hda Unable to open /dev/hda [root@volts root]# fdisk /dev/hdb Unable to open /dev/hdb [root@volts root]# cat /proc/partitions major minor #blocks name 3 0 4226040 ide/host0/bus0/target0/lun0/disc 3 1 2048256 ide/host0/bus0/target0/lun0/part1 3 2 819315 ide/host0/bus0/target0/lun0/part2 3 3 265072 ide/host0/bus0/target0/lun0/part3 3 4 1 ide/host0/bus0/target0/lun0/part4 3 5 208813 ide/host0/bus0/target0/lun0/part5 3 6 208813 ide/host0/bus0/target0/lun0/part6 3 7 208813 ide/host0/bus0/target0/lun0/part7 3 64 10002825 ide/host0/bus0/target1/lun0/disc 3 65 208813 ide/host0/bus0/target1/lun0/part1 3 66 1 ide/host0/bus0/target1/lun0/part2 3 69 208813 ide/host0/bus0/target1/lun0/part5 3 70 514048 ide/host0/bus0/target1/lun0/part6 3 71 514048 ide/host0/bus0/target1/lun0/part7 3 72 514048 ide/host0/bus0/target1/lun0/part8 I cannot make out what exactly is happening, any suggestions or can someone please point me to the right place to look for. Thanks for the help, Sharad. _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
