Once you have striped it, you are tied to the pvs used. If you think about it, this makes sense, as otherwise you have some stripes containing more data than others. In fact, as soon as the smallest pv is full, you will not be able to extend the lv, even if there is room in the other pvs. If you want to have the filesystem striped over all the disks, you will need to create a new lv which is striped across them all, transfer the data to it, delete the old lv and then extend the new one. Backups highly recommended. Michael --=20 Think Locally, Act Globally: =20 "It's cold in here ...
