Dear Friends


I created LVM and formatted it. But at the time of mounting it getting this error message ".....not a block device"

Please help Me!

Did you use a UI to create the LVM or did you create it manually? If the latter please post the exact steps you took and their output and the output of running 'fdisk -l; pvscan; vgscan', and 'lvscan; dmsetup status' (after running 'vgchange -ay'), preferably between BB code tags.

dear Friend

Hope this is what you asked

Please Help Me..................

The /dev/hda2 and /dev/hda3 Physical Volumes (PV) are part of the "lvmra" Volume Group (VG). The /dev/sda8 PV is NOT part of any VG. If you want to add /dev/sda8 to the "lvmra" VG then you should ('man vgextend',) 'vgextend lvmra /dev/sda8'. After doing that you could use 'lvextend' and 'resize2fs' to actually make use of available space.
