Hi,
I run Fedora 17.
I created a physical volume of 30GB on a disk with 60GB of space so there is 30GB of free space. On the physical volume, I created my volume group and logical volumes. I assigned all the space in the physical volume to my volume group. I need to add the 30GB of free space... (1 Reply)
hi guys, me again ;)
i recently opened a thread about physical to zone migration.
My zone is mounted over a "bigger" LUN (500GB) and step is now to move the old files, from the physical server, to my zone.
We are talking about 22mio of files.
i used rsync to do that and every time at... (8 Replies)
in the same VG?
Is there a way we can do this?
We basically have a test server that used to be a production server. Now the newly created test directories have run out of space and the old production directories have alot of free space. Can we transfer that free space over?
If so how? Have... (2 Replies)
Good afternoon! Im new at scripting and Im trying to write a script to
calculate total space, total used space and total free space in filesystem names matching a keyword (in this one we will use keyword virginia). Please dont be mean or harsh, like I said Im new and trying my best. Scripting... (4 Replies)
Friends ,
Using which command I can see the free space or usage of the Total HDD in Linux RHEL ?

Hi,
How do I determine the free space below?

HI
I'm a rookie in C programming and I'm working in Monta Vista Linux. I have to write a program that displays free memory. I have memtester(allready written by someone else) and now I have to type how much amount of memory tester will test and I want that memtester finds out himself how much of... (11 Replies)
LVEXTEND(8) System Manager's Manual LVEXTEND(8)NAME
lvextend - extend the size of a logical volume
SYNOPSIS
lvextend [--alloc AllocationPolicy] [-A|--autobackup y|n] [-d|--debug] [-h|-?|--help] [--noudevsync] [-i|--stripes Stripes [-I|--stripesize
StripeSize]] {-l|--extents [+]LogicalExtentsNumber[%{VG|LV|PVS|FREE|ORIGIN}] | -L|--size [+]LogicalVolumeSize[bBsSkKmMgGtTpPeE]}
[-f|--force] [-n|--nofsck] [-r|--resizefs] [-t|--test] [-v|--verbose] LogicalVolumePath [PhysicalVolumePath[:PE[-PE]]...]
DESCRIPTION
lvextend allows you to extend the size of a logical volume. Extension of snapshot logical volumes (see lvcreate(8) for information to cre-
ate snapshots) is supported as well. But to change the number of copies in a mirrored logical volume use lvconvert(8).
OPTIONS
See lvm for common options.
--noudevsync
Disable udev synchronisation. The process will not wait for notification from udev. It will continue irrespective of any possible
udev processing in the background. You should only use this if udev is not running or has rules that ignore the devices LVM2 cre-
ates.
-l, --extents [+]LogicalExtentsNumber[%{VG|LV|PVS|FREE|ORIGIN}]
Extend or set the logical volume size in units of logical extents. With the + sign the value is added to the actual size of the
logical volume and without it, the value is taken as an absolute one. The number can also be expressed as a percentage of the total
space in the Volume Group with the suffix %VG, relative to the existing size of the Logical Volume with the suffix %LV, of the
remaining free space for the specified PhysicalVolume(s) with the suffix %PVS, as a percentage of the remaining free space in the
Volume Group with the suffix %FREE, or (for a snapshot) as a percentage of the total space in the Origin Logical Volume with the
suffix %ORIGIN. The resulting value is rounded upward.
-L, --size [+]LogicalVolumeSize[bBsSkKmMgGtTpPeE]
Extend or set the logical volume size in units of megabytes. A size suffix of M for megabytes, G for gigabytes, T for terabytes, P
for petabytes or E for exabytes is optional. With the + sign the value is added to the actual size of the logical volume and with-
out it, the value is taken as an absolute one.
-i, --stripes Stripes
Gives the number of stripes for the extension. Not applicable to LVs using the original metadata LVM format, which must use a sin-
gle value throughout.
-I, --stripesize StripeSize
Gives the number of kilobytes for the granularity of the stripes. Not applicable to LVs using the original metadata LVM format,
which must use a single value throughout.
StripeSize must be 2^n (n = 2 to 9)
-f, --force
Proceed with size extension without prompting.
-n, --nofsck
Do not perform fsck before extending filesystem when filesystem requires it. You may need to use --force to proceed with this
option.
-r, --resizefs
Resize underlying filesystem together with the logical volume using fsadm(8).
Examples
"lvextend -L +54 /dev/vg01/lvol10 /dev/sdk3" tries to extend the size of that logical volume by 54MB on physical volume /dev/sdk3. This is
only possible if /dev/sdk3 is a member of volume group vg01 and there are enough free physical extents in it.
"lvextend /dev/vg01/lvol01 /dev/sdk3" tries to extend the size of that logical volume by the amount of free space on physical volume
/dev/sdk3. This is equivalent to specifying "-l +100%PVS" on the command line.
"lvextend -L+16M vg01/lvol01 /dev/sda:8-9 /dev/sdb:8-9"
tries to extend a logical volume "vg01/lvol01" by 16MB using physical extents /dev/sda:8-9 and /dev/sdb:8-9 for allocation of extents.
