i have like a tree with
LV0000
-> .
-> ..
-> test

i can go in test (the directory i created). I can go back to the root of LV0000 but not upper.
and considering that this unit, is the second i created, then shouldnt it b LV0001 ?

the RAID controller is new, there is 3 new disks... what else could it be ? which logfile could be the good one ?

there is an option in the CLI that i didnt try "restore LVM VG (volume group) configuration"
do you think it might help ?
