Cool How to increase size of Directory under RHEL 6.4

Dear Admins,

I have a VMware created under vSphere Client.

Type: Thin Provision
- Provisioned Storage: 78.85 GB
- Not-Shared Storage: 36.40 GB
- Shared Storage: 36.40 GB

Here is some info to know: I need to Resize to much bigger size like 20 GB
for the /Oracle note it's not on on the Root directory so no worries.

Filesystem Size Used Avail Use% Mounted on

/dev/sda1 20G 4.6G 14G 26% /

tmpfs 3.9G 0 3.9G 0% /dev/shm

/dev/sda6 16G 13G 2.3G 85% /oracle

/dev/sda3 4.9G 936M 3.7G 21% /tmp


300G 195G 106G 65% /oracle/export


400G 33G 368G 9% /oracle/bases

# parted /dev/sda6


Model: Unknown (unknown)

Disk /dev/sda6: 16.5GB

Sector size (logical/physical): 512B/512B

Partition Table: loop

Number Start End Size File system Flags

1 0.00B 16.5GB 16.5GB ext4

(parted) ### WHAT SHALL I INSERT HERE ??? ###

Is the following command right ?

Thank you for your assistance.

If I am reading your post correct, your /oracle directory needs additional space. Assuming that your vm is using lvm, then it should be pretty straightforward.


Add more disk (through vSphere)
Fdisk to create partition
umount the existing partition
Add partition to the pv (pvcreate /dev/sdx)
Expand the vg (vgextend /dev/sdx)
Expand the lv (lvextend /dev/sdx)
Expand the filesystem (e2fsck/resize2fs)

Also, if you're not accustomed to doing this work, take precautions. I'm a fan of backups and snapshots and whatnot. Practice on something less-than-mission-critical, first. Perhaps a clone of this very box.

One of my preferred methods is to clone the subject, perform the work, and then if that works, just leave the clone running as the replacement and the original machine off.

Good luck.
