I'm trying to mirror my root fs and get errors that make no sense. What am I missing? PV VG Fmt Attr PSize PFree /dev/sda1 vg0 lvm2 a- 111.79G 61.79G /dev/sdb1 vg0 lvm2 a- 111.79G 111.79G lvconvert -m1 -i 5 vg0/root Insufficient suitable allocatable extents for logical volume : 7680 more required Unable to allocate extents for mirror(s). Then I tried explicitly telling it to allocate from sdb1: lvconvert -m1 -i 5 vg0/root /dev/sdb1 Not enough PVs with free space available for parallel allocation. Consider --alloc anywhere if desperate. Unable to allocate extents for mirror(s). There are two PVs so why does it complain? _______________________________________________ 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/
