Good Day, I would just like to know if an error was made as we see something out of the norm after creating a mdX device. Created as follows : # pvcreate /dev/sdf # pvcreate /dev/sdg # fdisk /dev/sdf (Created a partition with type fd) # fdisk /dev/sdg (Created a partition with type fd) # mdadm --create /dev/md3 -l 1 -n 2 -b internal missing /dev/sdf1 # mdadm --add /dev/md3 /dev/sdg1 # mdadm -Dbv /dev/md3 >> /etc/mdadm.conf # dracut -f # pvcreate /dev/md3 # vgextend vgData /dev/md3 The abnormality we now see is as follows : # pvs PV VG Fmt Attr PSize PFree /dev/md1 vgSystem lvm2 a-- 44.46g 7.39g /dev/md2 vgData lvm2 a-- 399.87g 0 /dev/md3 vgData lvm2 a-- 29.98g 0 /dev/sdc vgBackup lvm2 a-- <100.00g 0 /dev/sdg lvm2 --- 30.00g 30.00g As you can see, /dev/sdg is now present in the output. How bad is this and can it be corrected ? I did create a VM on my laptop and recreated as per the above and did not see the same result. Regards Shaun
