You need to move 59604 extents but you only have 116 free on the destination. > root@fireball / # df > Filesystem 1K-blocks Used Available Use% Mounted on > /dev/mapper/data-data1 > 960906608 275263224 636841120 31% /data > So, I got space left on sdc but it won't move the data off sdb. Did > this run off into the ditch? :/ You have space in the filesystem, but the volume containing that filesystem is too large to move. You must first reduce the filesystem size, with resize2fs or whatever suits your fs, then shrink the LV with lvresize. That will free up enough extents to be able to fit them all on one disk. Look at the output from lvs to see what is taking up all the space. -- Neil Bothwick Men who have playful kittens shouldn't sleep in the nude.
