[linux-lvm] reconstituting a logical volume

["Larry Dickson" <ldickson cuttedge com>]

Hi all,

 

In the thread "lvm partition on ramdisk," circa May 19, you helped me get a FAT32 instance running on a lv that was a combination of a ramdisk (actually 3 of them) and an 8TB RAID array. Can someone tell me if the following is trivial, or possible, under LVM:

 

unmount the fs

dd the ramdisk[s] to equal sized volume[s] "rdcopy" on the array

break the composite ramdisk+8TB lv

create a rdcopy+8TB lv with the fs and its data undamaged and ready to mount

 

TIA,

 

Larry Dickson
