Filesystems GT 95%

[tedientang]

Hi

How can I only print the file systems that are more than 95% full.

I used the df -k output and tried to check for each file system and then print only the ones that meet the criteria... But my solution seems cloodgie ...

3. XFS is a full 64-bit filesystem, and thus is capable of handling filesystems as large as a million terabytes
4. Before delving into the differences between the ext2 and ext3 filesystems, a quick refresher on storage and filesystem terminology is in order

Hey, put your scripts up so that we can see if there is any better solution.

More Information:

1. In contrast to the older Linux style of having to explicitly mount filesystems, most of the time, libferris handles the mounting of filesystems for you
2. This applies to both extent based filesystems like JFS and XFS and to block based filesystems like 'ext3' (even if usually extent based filesystems
3. There are a lot of Linux filesystems comparisons available but most of them are anecdotal, based on artificial tasks or completed under older kernels
4. edu/~razvanm/fs-expedition/ - Cached - SimilarCreate and manage virtual filesystems in your Windows applications
5. Instead, we copy the data elsewhere, repartition the spare drive via the "normal" routes, reformat the filesystems, and copy the data back
6. After re-booting or re-mounting the file system, the partition will show up in the list of mounted filesystems as having quotas
7. filesystem on the back end to handle that, and it's those other parallel filesystems (PVFS2 in one case but more often proprietary) that I'd consider
8. Your system will present one logical filesystem, featuring a combination of both filesystems in a very specific way
9. The newfs utility actually formats your slice with the filesystems you previously specified with the disklabel utility

[saytinhkiemphap]

df -k |awk '($2-$3)/$2*100 > 95 {print $0}'



You can print $1(file-system) or $7(mounted directory) instead of $0



Good Luck

More Information:

1. Since partimage copies only used block of the partition, it must know the layout of the filesystem, and cannot save unsupported filesystems
2. Ts'o has an interesting article on his blog detailing how to align filesystems to an SSD's erase block size in linux, which [
3. Unionfs presents a filesystem interface to the kernel, and in turn Unionfs presents itself as the kernel's VFS to the filesystems on which it stacks
4. In the end, wouldn't it just be better if SSDs were plain raw memory and that filesystems were to do all the intelligent stuff ?
5. The EFSL project aims to create a library for filesystems, to be used on various embedded systems
6. One hard disk can contain one or multiple types of filesystems (each on at least one separate partition), and a filesystem of a single type can be spread
7. Having a small number of filesystems is usually a good idea for a number of reasons
8. This allows GmailFS (and other FUSE based filesystems to run under Mac OS X)

I had to search, but I had written this Perl script for automatic notification if the filesystem was greater than some arbirtary percentage:

Code:

#!/usr/bin/perl



# auswipe, 5 Apr 2002

# Tested under OpenBSD 2.9

# auswipe sez : "No guarantees!"



$upperLimit = 80;              # Upper Limit in % for a File System

$mailTarget = "joe\@blow.com"; # Target for the automatic e-mail message



open(STATS, "df -h\|grep '%'|") || die "$!";



my @fileStats = ;



foreach $entryLine (@fileStats) {

  chomp($entryLine);

  $entryLine =~ s/\s / /g;

  my @fsStats = split(/ /, $entryLine);

  $fsStats[4] =~ s/%//g;

  if ($fsStats[4] >= $upperLimit) {

    open(MAIL, "|mail -s \"FileSystem $fsStats[0] Getting Full!\" $mailTarget ") || die "Can't open m

ail!";

    select(MAIL);

    print << "EOF";



    The FileSystem $fsStats[0] is getting full.

    Currently, the file system is ${fsStats[4]}% full. The upper

    limit has been placed at ${upperLimit}%.



    Please attend to this matter.
