Sporadic writes to disk even though all torrents are paused

[Dennis J. <dennisj@…>]

Every few seconds deluge seems to write data to the disk causing I/O even though all torrents are paused. Here is what iostat says:

Total DISK READ: 0 B/s | Total DISK WRITE: 23.19 K/s

PID USER DISK READ DISK WRITE SWAPIN IO COMMAND 493 root 0 B/s 11.59 K/s 0.00 % 0.07 % [kjournald]

9024 dennis 0 B/s 7.73 K/s 0.00 % 0.00 % python /usr/bin/deluged -p 58846 9015 dennis 0 B/s 3.86 K/s 0.00 % 0.00 % python /usr/bin/deluge

Is this expected and if so what exactly does deluge have to write to disk every few seconds in this case?

Yuck! Let's try this again:

Total DISK READ: 0 B/s | Total DISK WRITE: 23.19 K/s
  PID USER      DISK READ  DISK WRITE   SWAPIN    IO    COMMAND
  493 root           0 B/s   11.59 K/s  0.00 %  0.07 % [kjournald]
 9024 dennis         0 B/s    7.73 K/s  0.00 %  0.00 % python /usr/bin/deluged -p 58846
 9015 dennis         0 B/s    3.86 K/s  0.00 %  0.00 % python /usr/bin/deluge

It could be simply flushing the disk cache or writing fastresumes (after pausing) or writing config files or writing state file.

Is there anyway you can see what files deluge is writing to at this time?

I think iostat calculates it's value since boot up and thus the disk write 'speed' is shown from boot to the time you run the command, it's not indicative of writes occurring at the time 'iostat' is run.
