Sparse files? How are you determining how much free space you have?
Thanks for your response.
I didn't attempt to find sparse files specifically but there were no files (or dot-files) at the top level of / that contained any significant data.
There sum of the sizes of all of the directories at the top level of / reported by du did not match the amount of disk space used at the time of the problem. I don't have a transcript of that session but I was using commands like:
find / -maxdepth 1 -xdev -type d | while read; do du -shx $d; done
I poked around in /var and /tmp a lot but didn't find anything that would contradict the output of the previous command.
At this point I started searching for deleted files for which the space had not been reclaimed. Finding nothing I though there was something I hadn't run into before and didn't know what to look for.
I'm not confident I understand your meaning in the second sentence. I didn't try to determine how much free space I had because there wasn't any. The root filesystem was at 100% capacity and services were failing. I was just trying to find out what had taken it all since normal usage is around 33% or so, according to df. Rebooting the computer eliminates the problem. When it comes back up, the disk usage is again at 33%. Whatever it is, vanishes during a reboot.
