Re: [linux-lvm] Failed to activate snapshot exception store.



Hi,


Thanks for the reply :-)


If I take the --test, yes the snapshot gets created
But if I try to create a new VG and after a new LV I get the same error. I can the work I was supposed to do, but would like to understand what's going on......


lvcreate -L 1G -n TEST vg_mysql_bk
Aborting. Failed to activate new LV to wipe the start of it.


vgdisplay -v vg_mysql_bk
Using volume group(s) on command line
Finding volume group "vg_mysql_bk"
