When installing Linux, I choose some default setting to use all the disk space.
My server has a single internal 250Gb SCSI disk. By default the install appears to have created 3 logical volumes
lv_root, lv_home and lv_swap.
fdisk -l shows the following
So the install appears to have created 2 partitions on /dev/sde i.e. /dev/sde1 and /dev/sde2
/dev/sde1 is the boot partition.
Q1. I am assuming that the logical volumes lv_root, lv_home and lv_swap are therefore using some of the space of /dev/sde2 - how do I prove / disprove that ?
Q2. During the linux install I decrease the size of lv_home to just over 50 Gb, leaving about 180 Gb unallocated. How do I see this unallocated space ?
any help appreciated,
Jim

Hello,
I need explanations about physical disks and physical volumes. What is the difference between these 2 things?
In fact, i am trying to understand what the AIX lspv2command does.
Thank you in advance. (2 Replies)
HI,
I have to find the length of the logical vol. that is spanned on different PV.
Now i have to find that is any bit map type structure of physical extents of any logical volumes and how i can find that.
Suppose I extend one LV on two PV on same VG.
How i can jump on the starting location... (3 Replies)
I have two 72GB disks that are mirrored and mounted (/backup). I have a 18GB drive in an array I just attached to the server, which is running Solaris 9.
I need to create a new logical volume partition and make the existing mirror device (/dev/md/dsk/d34) and the array's 18GB drive a member of... (3 Replies)
Hi!
Can anyone help me on how I can do a basic check on the Unix filesystems / physical volumes and logical volumes?
What items should I check, like where do I look at in smit? Or are there commands that I should execute?
I need to do this as I was informed by IBM that there seems to be... (1 Reply)

Someone please help me with how i can unmount and remove all the files systems from a cluster. This is being shared by two servers that are active_standby. (3 Replies)
Hi,
I am new to unix. I am working on Red Hat Linux and side by side on AIX also. After reading the concepts of Storage, I am now really confused regarding the terminologies
1)Physical Volume
2)Volume Group
3)Logical Volume
4)Physical Partition
Please help me to understand these concepts. (6 Replies)
Hello everyone,
I just read that while creating a logical volume(LV) we can choose the region of the physical volume (PV) in which the LV should be created.
When I say region I mean: outer edge - outer middle - center - inner middle and inner edge.
Can anyone help me understand the utility... (11 Replies)
Hello Guys,
I want to create a file system dedicated for an application installation. But there is no space in volume group to create a new logical volume. There is enough space in other logical volume which is being mounted on /var.
I know we can use that logical volume and create a virtual... (2 Replies)
Generally, this is what we do:-
On primary, export 2 LUNs (add-vdsdev).
On primary, assign these disks to the ldom in question (add-vdisk).
On ldom, created mirrored zpool from these two disks.
On one server (which is older) we have:-
On primary, create mirrored zpool from the two LUNs.... (4 Replies)

vxbootsetup
vxbootsetup(1M)vxbootsetup(1M)NAME
vxbootsetup - set up system boot information on a Veritas Volume Manager disk
SYNOPSIS
/etc/vx/bin/vxbootsetup [-g diskgroup] [medianame ... ]
DESCRIPTION
The vxbootsetup utility configures physical disks so that they can be used to boot the system. Before vxbootsetup is called to configure a
disk, the required volumes, standvol, rootvol and swapvol (and optionally, dumpvol) must be created on the disk. All of these volumes must
be contiguous with only one subdisk.
The -g option may be used to specify the boot disk group.
If no medianame arguments are specified, all disks that contain usable mirrors of the root, swap, /usr and /var volumes are configured to
be bootable.
If medianame arguments are given, only the disks that are associated with the specified disk names are configured to be bootable.
vxbootsetup requires that:
o The root volume must be named rootvol and must have a usage type of root.
o The swap volume must be named swapvol and must have a usage type of swap.
o The volumes containing /usr and /var (if any) must be named usr and var, respectively.
See the chapter "Recovery from Boot Disk Failure" in the Veritas Volume Manager Troubleshooting Guide for detailed information on how the
system boots and how VxVM impacts the system boot process. The vxmirror, vxrootmir, and vxresize utilities call vxbootsetup automatically.
If you use vxassist, or vxmake and vxplex to create mirrors of the root volume on a disk, you must run vxbootsetup explicitly to make the
disk bootable.
ARGUMENTS
medianame
Specifies the disk name (disk media name) of a VM disk that is to be configured as bootable.
