Another piece of information: I found the logs as: Device-mapper: device /dev/hda1 too small for target Device-mapper: dm-linear: Device lookup failed Device-mapper: error adding target to table Device-mapper: device /dev/hda5 too small for target Device-mapper: dm-linear: Device lookup failed Device-mapper: error adding target to table So there seems to be some size problem. blockdev --getsize /dev/hda1 = 2041137 blockdev --getsize /dev/hda5 = 1043217 Is there a limitation on the size of the device or is this a bug?

Hi, I wanted to create a mapped device for all the physical partitions on my disk. Following is the partition information: /dev/hda1 /boot /dev/hda2 / /dev/hda3 /home /dev/hda5 swap I am using device-mapper to create the mapped device. I execute the following command: #echo 0 $(blockdev --getsize /dev/hda1) linear /dev/hda1 0 | dmsetup create hda1 I am doing the same thing for all the devices. I am able to create mapped devices for /dev/hda2 and /dev/hda3. But /dev/hda1 and /dev/hda5 give me the following error: device-mapper ioctl cmd 9 failed: Invalid argument I am unable to understand as to why should hda1 and hda5 behave differently. Any help is appreciated. Regards, Manu
