Why does DF-H not show the deleted space?
If you delete files from the filesystem, the command “ df -h ” might not show the deleted space as being available. This is because the deleted files could still be held open by (defunct) processes, where the file descriptor handles still point to those files.
Why do ” DF ” and ” du ” commands show different disk usage?
While df is to show the file system usage, du is to report the file space usage. du works from files while df works at filesystem level, reporting what the kernel says it has available. Continue reading the du manpage support this: Summarize disk usage of each FILE, recursively for directories. it says du works with files.
Why does DF show up differently than du?
This space will be reclaimed after the process has closed the inode. This can be done by stopping the process or killing it. So with the process killed off, the space should be allocated back and df should show up differently. The following compares ls output with that of du and df for sparse files.
What’s the difference between DF and Du in Windows 10?
While df is to show the file system usage, du is to report the file space usage. du works from files while df works at filesystem level, reporting what the kernel says it has available.
Why is the df command not updating the diskspace?
Df command in Linux not updating actual diskspace, wrong data. This is an annoying problem on a lot of Linux distributions, and it can have several causes. Caused by open file descriptors. If you delete files from the filesystem, the command “df -h” might not show the deleted space as being available.
Why are filesystems-DF not showing correct free space?
Even after space will be reclaimed by deleting files/directories, non-root user won’t be able to write to particular partition. You can easily check if that’s your case by trying to create a file on a device as root and non-root user. and calculating actual % on your own. The file is still locked by the process opening it.
What causes Df-h and Du to mismatch?
In my case the df -h and du -sh mismatched by about 50% of the hard disk size. This was caused by apache (httpd) keeping large log files in memory which had been deleted from disk. This was tracked down by running lsof | grep “/var” | grep deleted where /var was the partition I needed to clean up.
How much free space is there on my hard disk?
As the output of df -h shows here, something is eating up 5GB of free space. So, it’s not available to use. I’m also noticing sometimes that the hard disk gets filled up to 100% sometimes.
