What are these files and can I delete them?


So we ran out of space on a development server we have. I used this command to find a list of large files: find / -type f -size +20000k -exec ls -lh {} \; | awk '{ print $9 ": " $5 }'

Below is the output of the above command followed by the output of df and two directories that are the most troublesome (/root/import/export/ and /usr/local/mysql/var/)

I dont know what files are safe move to the data directory and which are safe to delete. I'm pretty sure that database.sql.gz gets overwritten daily by rsync. Appreciate any advice.

where you have a file with .tar.gz and another with the same name that is just .tar
the .tar.gz one is normally safe to delete, as it is only a compressed version of the tar file...


apart form that i would empasise extreame caution when doing things to files that you diddnt create in the first place.

eg if you delete /var/lib/rpm/pakages you will totally mess up your pakage manager.



to free up space i woudl recomend fireing up your pakage manager and deslecting things that yoyu wont be needing, eg. as your box is a developemant server do you really need the games taht are likly installed by default?

your pakage manager will be able to sort out the dependancys for you and should not break things if you only uninstall thinsg that you know you wont use



either that or just add some more hardrive space pure and simple,
its not as if hard drives are expensive anymore

Thanks dasy,

We've purchased a new drive which runs on sata II but we're getting a kernel error (I dont have the error handy). We think it may be a bios setting or a setting on the motherboard.

I've moved all the zipped files which free'd up 250MB. I talked to a couple people about the giant mysql files and we think they are backups based on the mod dates. Once confirmed, we will set up a cron to start eliminating all but the most recent backup on a daily basis.

Thanks for the help!

Turns out those mysql files (/usr/local/mysql/var/localhost-bin.000001 and so forth) are binary update logs. Here's a snippet...

[snippet]
The binary update log is activated by placing
log-bin[=binary_update_log_filename]
in your configuration file (you should know where that is by now!). The filename is optional, and if you do not supply it, the log will be named hostname-bin, with hostname being the name of the host. Any extension (the last 3 letters after the dot) you supply will be dropped, as MySQL creates its own, starting at 001. This log stores all updates to the database in an efficient binary format (the deprecated Update Log stores the same data in a less compressed format). The binary log stores each SQL statement that makes a change to the database in the same order as they were executed, and for this reason is useful for restoring backups, or for replication. MySQL comes with an executable binary that allows you to view the contents of the binary update log; (since it is a binary format, viewing it in a text editor is no use). It's called mysqlbinlog, and can be accessed as follows, to view the sample binary update log.
[/snippet]

Hope this helps others!

Cheers!

Actully, if you've got xxx.tar and xxx.tar.gz, keep the gzipped one, it'll be smaller....
Also, looks like a lot of those (.tar.gz) also have same-named dirs. IOW, when the xxx.tar.gz was unzipped/untarred, it installed itself into the named dir.
Therefore, you don't technically need the .tar.gz file anymore (although you might want to back them up before deletion).
In fact, if you are unsure about any(!) file, back it up first. That way you can always put it back if you're wrong, but make a note for future ref, so you know which ones are good to go.
