Hi We use AoE disks for some of our systems. Currently, a 15.65Tb filesystem we have is full, I then extended the LVM by a further 4Tb but resize4fs could not handle a filesystem over 16Tb (CentOS 5.5). I then reduced the lvm by the same amount, and attempted to create a new LV, but get this error message in the process lvcreate -v -ndata2 -L2T -t aoe Test mode: Metadata will NOT be updated. Setting logging type to disk Finding volume group "aoe" Test mode: Skipping archiving of volume group. Creating logical volume data2 Test mode: Skipping volume group backup. Found volume group "aoe" Aborting. Failed to activate new LV to wipe the start of it. Found volume group "aoe" Unable to deactivate failed new LV. Manual intervention required.

So any ideas what step I've missed to enable me to create the new LV ? Thanks Phil.
