Unfortunately even rebuilding (converting to linear and back to raid1) doesn't work. lvconvert seems to ignore the --regionsize option and use defaults: lvconvert -m 0 /dev/vg_sys/lv_test lvconvert --type raid1 -m 1 --regionsize 128M /dev/vg_sys/lv_test [10881847.012504] mdX: bitmap initialized from disk: read 1 pages, set 4096 of 4096 bits ... which translates to a regionsize of 512k for a 2G volume. :-( Cheers, --leo -- e-mail ::: Leo.Bergolth (at) wu.ac.at fax ::: +43-1-31336-906050 location ::: IT-Services | Vienna University of Economics | Austria _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
