So I did not have any usb sticks large enough for this task (only 4Gb) so I restarted into emergency runlevel with only / mounted and as ro, I hope that'll do. >> >> It's better to provide two trace. >> One is the function tracer one, with "btrfs:*" as set_event. >> The other is the function_graph one. with "btrfs_mount" as >> set_graph_function. So I got 2 new traces, and I am hoping that these are what you meant, but I am still not sure. Here are the commands I used in case...:
trace-cmd record -o trace-function_graph.dat -p function_graph -g btrfs_mount mount MountPoint and trace-function_graph.dat -p function -l 'btrfs_*' mount MountPoint (using -e btrfs only lead to a crash but -l 'btrfs_*' passed, though I am sure they have different purposes.. I hope that's the correct one) The first one was so big, 2Gb, I had to use xz to compress it and host it somewhere else, the ML would most likely not take it. The other one is quite small but I hosted it in the same place....
