Let's assume I have two physical disks:
/dev/sda1
- hard disk
/dev/sdb1
- SSD disk
I create volume group:
sudo vgcreate hd_and_sd_vg /dev/sda1 /dev/sdb1
Now I create logical volumes:
lvcreate -L 10G -n my_test_volume_on_hd VolumeGroupName /dev/sda1
lvcreate -L 10G -n my_test_volume_on_sd VolumeGroupName /dev/sdb1
I can use command such as pvdisplay -m
to confirm that extents are distributed correctly. my_test_volume_on_hd
LV sits on hard disk, my_test_volume_on_sd
LV sits on SD.
Now /dev/sda
hard disk dies.
Can I still access the data on my_test_volume_on_sd
?
Thanks
