I'm trying to get free space in GB of file system into parameter.
I have the following code:
My question is ,how can I cut in the "df -h" command the "G" sign from the output , because I want to do manipulations on a numeric result?
How to find the free size currently FileSystem has, on the disk mounted?
I know 'df' lists all the mounted disks, but I am interested to know details
for the filesystem, in which currently I am working. (7 Replies)
Hi everybody,
I got a problem on my SUN server in Solaris 9. I'll try to explain, if somebody could help me.
I have mounted some volumes in RAID 0+1, that is stripped slices and then mirror. To be clear the result of metastat d80 is as follow :
d80: Mirror
Submirror 0: d81
State:... (2 Replies)
dear all,
I have some problem in my file system :
df -k result :
...
/dev/md/dsk/d3 3101839 2736380 303423 91% /var
...
it occupied around 2.7 gb
but when I tried command
du -sk /var
813991 /var
so /var only have around 800Mb , Do you know why there is many difference... (6 Replies)
How to get free disk space size in C/C++ program( Solaris system)?
Is there any standard function or system function? Just like "df" or

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)
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)
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 Friends,
I want to cut space from one file system and add in another file system.
For example I have 100 gb space in /oracle/TST/oraarch
I wnat to cut 50 gb from this file system and add 50 in /oracle/TST/sapdata1.
Please hel, How I can do it.

A file system has reached 100%. I have tried adding space using chfs -a size=+100 command to that file system. However, the % used is not decreasing from 100%. Is there a way to add more space?
Also, can someone suggest a script to send a mail alert when a file system is reaching 90%.

bup-margin
bup-margin(1) General Commands Manual bup-margin(1)NAME
bup-margin - figure out your deduplication safety margin
SYNOPSIS
bup margin [options...]
DESCRIPTION
bup margin iterates through all objects in your bup repository, calculating the largest number of prefix bits shared between any two
entries. This number, n, identifies the longest subset of SHA-1 you could use and still encounter a collision between your object ids.
For example, one system that was tested had a collection of 11 million objects (70 GB), and bup margin returned 45. That means a 46-bit
hash would be sufficient to avoid all collisions among that set of objects; each object in that repository could be uniquely identified by
its first 46 bits.
The number of bits needed seems to increase by about 1 or 2 for every doubling of the number of objects. Since SHA-1 hashes have 160 bits,
that leaves 115 bits of margin. Of course, because SHA-1 hashes are essentially random, it's theoretically possible to use many more bits
with far fewer objects.
If you're paranoid about the possibility of SHA-1 collisions, you can monitor your repository by running bup margin occasionally to see if
you're getting dangerously close to 160 bits.
OPTIONS --predict
Guess the offset into each index file where a particular object will appear, and report the maximum deviation of the correct answer
from the guess. This is potentially useful for tuning an interpolation search algorithm.
--ignore-midx
don't use .midx files, use only .idx files. This is only really useful when used with --predict.
EXAMPLE
$ bup margin
Reading indexes: 100.00% (1612581/1612581), done.
40
40 matching prefix bits
1.94 bits per doubling
120 bits (61.86 doublings) remaining
4.19338e+18 times larger is possible
Everyone on earth could have 625878182 data sets
like yours, all in one repository, and we would
expect 1 object collision.
$ bup margin --predict
PackIdxList: using 1 index.
Reading indexes: 100.00% (1612581/1612581), done.
915 of 1612581 (0.057%)
