umount /lib/bootchart/tmpfs: Device or resource busy #6

I have added the proper arguments to /boot/grub/menu.lst, but bootchart.tgz is still not created.

Here's the log:

$ dmesg | grep bootchart Kernel command line: ro root=/dev/sda3 initcall_debug printk.time=y quiet init=/sbin/bootchartd vga=0x037b 3 [ 4.515213] bootchart-collector started as pid 824 with 1 args: '50' [ 4.515216] bootchart-collector run outside initrd [ 4.515217] bootchart collector already running as pid 823, exiting... [ 4.764974] bootchart continuing boot [ 32.704138] bootchart-collector started as pid 1940 with 2 args: '--dump' '/tmp/bootchart.TdLggrvdT6' [ 32.704143] bootchart-collector unmounted proc / clean exit [ 32.704145] umount /lib/bootchart/tmpfs: Device or resource busy

For some reaseon /lib/bootchart/tmpfs is busy?

If I do: $ sudo umount /lib/bootchart/tmpfs It succeeds.

How can I fix this?

Ah ! ignore that warning - that it can't unmount. We are just running two collector processes at once, and it's not a real problem. Can you confirm that the data is dumped nicely into /tmp/bootchart.TdLggrvdT6 ? [ or whatever it says in dmesg ? ]. I suspect that the root cause of the badness is in the shell piece now - whose errors will not go to dmesg - but may show up in syslog or on your console (did you check there). if you read /sbin/bootchartd - you see the 'log_header' method ... Most likely something it calls is missing - and our error toleration is pretty pathetic there. eg do you have 'lsb_release' installed ? :-)

Hah - ok, so I discovered a truly dumb remote argument parsing mistake that was causing this; and just pushed a fix, can you test with this fix:

Fix horrible snafus with remote argument parsing...

Thanks :-)

Okay, that fixes it. Thanks.
