When running from the Hardy "Live CD", an error still occurs as follows when doing "dmsetup ls", even if "sudo" is used:
[EMAIL PROTECTED]:~$ sudo dmsetup ls /proc/misc: No entry for device-mapper found Is device-mapper driver missing from kernel? Failure to communicate with kernel device-mapper driver. /proc/misc: No entry for device-mapper found Is device-mapper driver missing from kernel? Failure to communicate with kernel device-mapper driver. Incompatible libdevmapper 1.02.20 (2007-06-15)(compat) and kernel driver Command failed A workaround is to do "sudo modprobe dm_mod" to load the device-mapper module, then the result is as follows: [EMAIL PROTECTED]:~$ sudo modprobe dm_mod [EMAIL PROTECTED]:~$ sudo dmsetup ls No devices found [EMAIL PROTECTED]:~$ sudo modprobe -r dm_mod Similarly, attempting to use "cryptsetup" without first loading dm_mod, the error is confusing. For example, if you want to use block device /dev/sdX4 with dm-crypt (http://www.saout.de/misc/dm-crypt/): [EMAIL PROTECTED]:~$ sudo apt-get -y install cryptsetup [EMAIL PROTECTED]:~$ sudo cryptsetup create volume1 /dev/sdX4 Command failed: Incompatible libdevmapper 1.02.20 (2007-06-15)(compat) and kernel driver Whereas when device-mapper is loaded, the user is prompted for the passphrase, as expected: [EMAIL PROTECTED]:~$ sudo modprobe dm_mod [EMAIL PROTECTED]:~$ sudo cryptsetup create volume1 /dev/sdX4 Enter passphrase: Anyways, those are just a couple of other ways the same issue can present itself to the user, that might be handy to mention (as launchpad is of course widely indexed). -- dmsetup: boneheaded errors when invoked with insufficient privileges https://bugs.launchpad.net/bugs/164184 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
