Unable to delete files in /tmp/kdecache : Input/output error


Hello everyone,

I upgraded my Acer travelmate laptop hdd end of last month from an 80g to a 120g using dd, this being the second time this year as it only had a 40g originally - so I had practice!
This time I started getting disk access problems------couldn't access stuff I seem to have lost my notes - they are spread around on bits of paper but I did run fsck on the drive and this is what I got....(28/09/08)

[root@max guest]# fsck /dev/hda7
fsck 1.39 (29-May-2006)
e2fsck 1.39 (29-May-2006)

I stopped using ktorrent as it appeared to be the cause, it did cure the disk access problem, and I uninstalled it with synaptic and tried to remove all related files. I could not remove a chunk of files listed in /tmp/kdecache. I still have not come up with an answer to this so I thought I would post it!

1.8T .

I presume the 1.8T above is refering to capacity but this can't be right can it on an 20g drive!! being a newbie, well since the beginning of this year I feel this has something to do with inodes, as if this lot have lost theirs and thats why I can't delete them. Despite reading a lot on Linux, inodes still mystify me a bit. Sorry if this is long winded - just thought I would give you the whole story. Oh and I'm running PCLinuxOS.
Thanks.

First off when you copy partitions using dd you lay yourself open to all kinds of errors in the filesystem structure. I recommend that in the future you format the new partition using mkfs and then copy the files using cp. That will save you a lot of headaches in the long run.

As to your current problems in /tmp: By definition anything in /tmp is temporary. Boot a live CD and mount your / partition on a temporary directory. Then try deleting everything in your /tmp directory. Something like:

mkdir /deltmp
mount -t ext3 /dev/hda1 /deltmp
rm /deltmp/tmp/* -R

Take a look at the following man pages to tailor the commands to your needs:

man mkdir
man mount
man rm

If the rm command works without any errors then your /tmp should be OK when you reboot.

Thanks Steve,

I used dd because it seemed the logical and most straightforward thing to do and it had worked without fault before, I also have a partition containing xp that I wanted to keep.

Anyway, tried your suggestion, booted up with my live cd and followed your instruction substituting the relevant partition but it still cannot delete anything under /tmp/kdecache-pierre/http/t/

Thanks again for your quick reply
