Bug#497360: iotop: "Linux >= 2.6.20 with I/O accounting support: Not found" but 2.6.22 Debian kernel here

[Sandro Tosi]

Package: iotop
Version: 0.2-2
Severity: normal

Hello,
I'd like to prove iotop but just after installation, running it I got:

$ iotop
Could not run iotop as some of the requirements are not met:
- Python >= 2.5 for AF_NETLINK support: Found
- Linux >= 2.6.20 with I/O accounting support: Not found

even if the kernel used is 2.6.22 Debian kernel:

$ uname -a
Linux zion 2.6.22-2-amd64 #1 SMP Thu Aug 30 23:43:59 UTC 2007 x86_64 GNU/Linux

$ dpkg -l "*2.6.22-2-amd64*" | grep ^ii
ii linux-image-2.6.22-2-amd64 2.6.22-4

So, either there is a bug somewhere or a lack of documentation (for example
in requiring to recompile by hand the kernel), maybe a depends/recommends(?).

Thanks,
Sandro

Thanks for considering.

As discussed on IRC, notifying the users of the needed kernel options
(eventually what Debian kernel provide them, like 2.6.26) would be a
plus, so that a user does not have to install the package and then
discovers he needs to recompile the kernel.

Due to freeze, and the low priority, it's enough to have it in lenny+1
(aka squeeze).

Cheers,
Sandro

Please read the manual page, it explains that you need at least the

CONFIG_TASKSTATS and CONFIG_TASK_IO_ACCOUNTING Linux config options.
Please install a Linux image that includes these options and close the
bug if that fixes your issue.
