So here are mt symptoms. Over the last few days I start the day with say 33 GB of space and then come in the next day to see that I have only 1GB of space left. I am assessing space by using "df"
hari@hari-Precision-WorkStation-T7500:~$ df Filesystem 1K-blocks Used Available Use% Mounted on /dev/sde1 230398116 216818952 1852572 100% / none 4 0 4 0% /sys/fs/cgroup udev 6135136 4 6135132 1% /dev tmpfs 1229864 1588 1228276 1% /run none 5120 0 5120 0% /run/lock none 6149304 5808 6143496 1% /run/shm none 102400 56 102344 1% /run/user //server01.mycompany.com/archive$/Biology/RAW-Data 8458860528 4685045352 3773815176 56% /home/rawdata2 /dev/sda1 1953512032 1724815580 228696452 89% /media/hari/FreeAgent GoFlex Drive1
The only change I did to my system was mount a 9 TB fileshare using the cifs (samba) module before this problem started.
When I run the disk usage analyser "baobab", it reports on the disk without suggesting that any single directory under my home has grown overnight significantly - i.e the percentages don't go up significantly.
I am running a private webserver on this machine and not running much else on this machine. There are no logs that are growing significantly overnight nor are there any processes that have much disk io as investigated by "htop" "top".
I tried to use "sudo iotop" but I dont know how to interpret its output.
Where is my disk space going. I am scared it is some indexer that is trying to index the 9TB fileshare that is holding on to some space since the problem started after I added the 9TB fileshare.
I am running Ubuntu 13.10 , 3.11.0-15-generic
How do I troubleshoot whats using all this space. I am scared its some indexer or some other background process.
