hi i have a server which its first hdd was broken , the server has 2 HDD , the first hdd crashed . datacenter replaced it for me with a new hdd.
the second hdd use to have 2 pv on 2 partitions , and both PV where added to 1 vg , and 1 lv used allof the vg available space.
/dev/mapper/vg1-lv1 2.7T 255G 2.4T 10% /mnt/home2
/dev/sdb1 --> pv /dev/sdb2 --> another pv
both these PV where added to vg1 , vg1 had one 2.7 TB lv1 /dev/mapper/vg1-lv1 was mounted as ext4 on /home2
now the problem is that datacenter replaced the hdd , and i installed a new OS on the first hdd , but linux do not see second hdd PV or LV or VG .
i dont know if i do
pvcreate /dev/sdb1
and
pvcreate /dev/sdb2
so that they get a UUid , will the linux see the rest vg/lv ?
or if i do pvcreate it will break the existing lvm on it ?
