Hi, I'm not familiar with ubuntu. In SLES one has to enable the boot.lvm script which runs vgscan and vgchange to detect and enable the PV's, VG's and their LV's. Try manually running vgscan and then vgchange -a y and see if that helps. good luck. -------------------------------------------------------- This e-mail, including any attachments, may be confidential, privileged or otherwise legally protected.

All I want to know is what other modules/libraries other than the device-mapper kernel module, lvm2 and the devmapper library do I need in order to have my logical volumes detected. here's my setup: one 160GB sata2 hdd; one 320GB sata2 hdd; a minimal version of ubuntu (installed from debootstrap) and a custom compiled kernel version 2.6.26 (I should mention that the kernel doesn't contain all of the modules - I wanted it to provide only the features I need). I have created a physical volume, volume group and logical volume from another ubuntu installation. It is detected while using the live cd, and also if I boot the minimal ubuntu with another kernel that has a full set of features. regards, Eduard -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
