Diskspace
-
I appear to be running out of disk space. I think some uninstalled package files might still be there or some partial updates. Where/how do I find these to delete them.
What command line can I give to list the top files sizes.
This issue is causing my squid to stop working. How to I delete my cache?
-
The amount of discspace squid can use can be edited in the squid web gui (Cache Mgmt). but there is normally a low and high watermark which causes squid to empty the cache.
but if you do NOT use a log rotate, this could perhaps be the problem of running out of space. -
Thanks for that but where do I find the log so I can empty it
-
/var/squid/log/access.log
-
The file was only 9mb but I emptied it anyway…. didn't help

The cache can be deleted using "rm -rf /var/squid/cache/".
Then create new cache folders by running "squid -z"(or lowering the "Hard disk cache size" and resynch, but it will take forever to complete)
Tip: try tuning high and low watermark to be closer together.
default difference is 5% (90% – 95%) but with a multiple gigabyte cache on the hard drive this 5% represents a lot of extra ram/diskspace.Also a lot of Hard disk cache also takes up more RAM, thumb rule: ~100MB RAM per gigabyte. (if I remember correctly)
It also depends on how large the largest cached object may be.
If you set this option to "large" the squid program may use more room than every option added together, because it may keep more than 1 object with the "large" size in cache or memory adding to the total allowed MB's or GB's. -
I'm still getting the following ….. obviously I have a space problem. I did what was recommended above. I need some pointers as to which directories I can empty or how I go about fixing this. If I was in a windows box I would be fine but alas I don't know my way around Linux well enough.

Overall I appear to have enough space.
The log suggests you don't have enough space. I run which a basic pfSense on a 1GB hard drive of which 260MB is reserved for swap. But I don't run any applications that seriously use the disk.
I really need someone to explain to me what's going on? ???
My guess: some application or applications open one or more temporary files which are allocated space which is released when the application exits.
How long from startup does it take for the appearance of a report the / file system is full? (If this is long enough it might be possible to get some clues pointing to the culprit.
How is the system with the df output different from the system reporting the full root file system? (squid was disabled?)
-
There is more than one way to run out of space on a drive.
Check the output of:
df -iIt could be out of inodes if you have a large number of very small files.
Or you could also have hardware problems.

You aren't running out of disk space then unless Squid is doing it and deletes whatever it's creating when it dies. Disk failures can present themselves as disk full messages as odd as that seems even when the disk isn't full. If you can manage to log in while it's still reporting the disk is full and getting that same info it may be helpful in determining whether you're really running out of disk space, or your disk is dying.

Was you reply came in I was postinvg the following: After leaving it for a day I returned to trouble shoot and noticed that the logs where now fine… enabled squid and safesquid and its working.... I'm inclined to go with your faulty disk diagnosis....The next question then is how does one transfer this to a new disk?? But I suppose that's for a different forum.
