File Browsing Suddenly slow - 'exports' file?


All of sudden today the KDE File Browser became very slow.

When I launched the file manager the 'spinning icon' hung for several seconds on 'root folder' before then showing the full directory tree. After that the directories could be browsed at normal speed. This behaviuor was repeated on re-boot of the PC.

Another observation was the if I created a text file in Kwrite, when I went to save it there was a long hang whilst the directory tree was created in the 'Save As' dialogue.

I thought that something serious had possibly happened to the drives so I forced an FSCK but this did not reveal any problems.

I totally uninstalled KDE and installed again fresh from the CD.

Still the problem persisted.

Then just browsing through the /etc directory I noticed a file called 'exports' of 10mb size that I did not recognise. I deleted this file and now the file manager is back to normal behaviour.

So my obvious question is how did this file come to be created and for what reason.

Can anyone throw any light on this for me please?.

Bill.

Well, /etc/exports is the file that controls which directories and/or filesystems are shared out over NFS. It is a standard file and should be present in a full Slackware install.

However, it should never be 10 MB. That is insane, it is a plain-text file that only holds a few lines of text to describe the various shares, only a couple hundred bytes at most.

I don't know what conditions could cause the file to get so large, and would have been very interested to see what was in it. Since you deleted it this is somewhat of a mystery.

I guess the file originally got installed on my system when I installed the NTFS package. I subsequently uninstalled NTFS quite some time ago,

Th 10MB file could be oped in KWrite, but the only visible information was the few lines of explanatory text at the top which I assume is in the original /etc/exports.new file. A puzzle why it suddenly grew very large an brought my file browsing speed down to a crawl. Today, I had shared a directory on the PC using Samba to let another PC on my network copy a file, but I have done this many times before without any problems.

Bill.
