Hi,
Just wanted to confirm that what Im doing is correct to calculate the space allocated to filesystem:
>df -k .

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)
I am running HP-UX 11.31 ia64. The /usr filesystem shows 7 GB as the size, but the logical volume that is mounted there shows 13 GB. Is there a way to get the entire 13 GB to show up and why did this happen in the first place? (11 Replies)
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)

E2FREEFRAG(8) System Manager's Manual E2FREEFRAG(8)NAME
e2freefrag - report free space fragmentation information
SYNOPSIS
e2freefrag [ -c chunk_kb ] [ -h ] filesys
DESCRIPTION
e2freefrag is used to report free space fragmentation on ext2/3/4 file systems. filesys is the filesystem device name (e.g. /dev/hdc1,
/dev/md0). The e2freefrag program will scan the block bitmap information to check how many free blocks are present as contiguous and
aligned free space. The percentage of contiguous free blocks of size and of alignment chunk_kb is reported. It also displays the mini-
mum/maximum/average free chunk size in the filesystem, along with a histogram of all free chunks. This information can be used to gauge
the level of free space fragmentation in the filesystem.
OPTIONS -c chunk_kb
If a chunk size is specified, then e2freefrag will print how many free chunks of size chunk_kb are available in units of kilobytes
(Kb). The chunk size must be a power of two and be larger than filesystem block size.
-h Print the usage of the program.
EXAMPLE
# e2freefrag /dev/vgroot/lvhome
Device: /dev/vgroot/lvhome
Blocksize: 4096 bytes
Total blocks: 1504085
Free blocks: 292995 (19.5%)
Min. free extent: 4 KB
Max. free extent: 24008 KB
Avg. free extent: 252 KB
