wheres my disk space going?
Ive an oracle install on rh 4 (I think its 4, not in front of it, on another site).
/u01 has the oracle binaries, 20gb volume. If as root I cd to /u01 and a du -sk, I can see total directories total 14gb. If I do a df -k, /u01 has 19gb used. Wheres the other 5gb? Wherever its gone its increasing usage a few mb every few minutes. Ive cleared down many gb, Ive no tracing, loggin or auditing. Can there be something memory related eating that disk that wouldnt show up in a du search? From /u01 as root I also did ls -lR >> file1 , waited 30 minutes, ls -lR >> file2 diff file1 file2 >> diffs showed nothing, few small log files oracle related but nothing to show whats eating the space. Anyone? |
Hi, do you realise, that, when do you do du -k from directory position you will see directory containing data size, but when you just do df -h or -k /something, you'll see just the volume(partition)size of course it will be more data, then just du -h or -k from directory state

logon as root cd /u01 du -sk * dir1 = 5gb dir2 = 5gb dir3 = 4gb = total 14gb now do df -k u01 vol =20gb used = 19.5bg free= .5gb what are you saying there? |

You might have files that are deleted but still 'in use' by an application. See http://www.linuxquestions.org/questi...rom-du-632127/

If it was something temporary memory related where a process on the box used a chnk of disk space for memory, but Ive never heard of this in 15 years in oracle where oracle used disk space on /u01 to do this. This box has been in use for last 2 years and this is first instance of it. All very strange. Thanks for suggestions. |
