I want to allocate several large blank files on HD, and make them into virtual hard disk which I mount using loop.
I then want to treat them as 'physical volumes' under LVM, and collect them into a single volume group. Then, I intend to define a few larger logical volumes on this 'volume group'. I do this because I want to store large files on a HD whose hardware interface limits file sizes to 4Gb, and I want to store larger files than 4Gb. ( The HD has 500Gb total capacity.) My problem is that I can't figure out how to execute pvcreate on my 'image physical volumes'. If I mount the image, I think I should apply pvcreate to /dev/loopxx, but that doesn't work, giving a message that the volume is mounted. If I unmount the image, I get (blk0 is my file to be initialized) : big:/media/WDP-5/blks# pvcreate -f blk0 Device blk0 not found (or ignored by filtering). How can I associate a loop device node with a particular file, without mounting it? Or how can I get pvcreate to write whatever it puts on a phisical volume into a file on disk? Or how can I mount a loop device without specifing a fils system type? Or, etc.?
