This is my lsblk output:

lsblk
NAME            MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda               8:0    0   500G  0 disk

sr0              11:0    1  1024M  0 rom

As you can see that I have 2 centos-home entries, 1st one under sda2 and the 2nd under sda3.

How does that happen? Why?

EDIT: This is my fdisk -l output:

# fdisk -l

  • Why can't you have partitions with same name on different disks? – harrymc Aug 02 '23 at 15:29
  • An effect of using LVM, I presume? https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9/html/configuring_and_managing_logical_volumes/overview-of-logical-volume-management_configuring-and-managing-logical-volumes – Hannu Aug 02 '23 at 16:45
  • @harrymc They are actually the same partition mounted to same directory. – ramazan polat Aug 02 '23 at 18:09
  • One is under sda2 and the other under sda3. If they are the same partition, then might it be mounted again? – harrymc Aug 02 '23 at 18:31
