It has been more than 2 month i switched to linux but i m still very much confused how linux handles and names the partitions.
I have gone through couple of beginners material and found linux doesnt treat partitions as c: and d: instead it uses /dev/hda1 /dev/hda2 hda3 .But now i have come across something like dev/sda1 dev/sda5 tmpfs
Please find output of df -h
[root@test ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 3.9G 867M 2.9G 24% /
/dev/sda1 99M 45M 49M 48% /boot
tmpfs 285M 0 285M 0% /dev/shm
/dev/sda5 1.1T 561G 544G 51% /var/ovs/mount/F179080BDBFD4C5596D03242EFE5179C
I have few questions regarding the same.
1)Why there is no sda2 sda 4 present?
2)What is tmpfs ?
3)What is the difference between sda and hda
4)I also heard there is something as LVM.(How do i know whether my drives are LVM supported or not?
If they are supported how do i extend the drives.
I know these are pretty basic for advance user but i m still a learner in linux . Please help.
