FileSystemCollector never ends in Ubuntu 18.04 LTS

There is a problem running “asa collect -a” in Ubuntu Linux 18.04 LTS and to be precise the file system collection. For some reason following commands never finish. I tested this with three different virtual machines that on different virtualization platforms (Oracle VirtualBox and XenCenter):

1. sudo .dotnet/tools/asa collect -a --overwrite --verbose --runid initial
2. sudo .dotnet/tools/asa collect -f --overwrite --verbose --directories /proc --runid initialproc
3. sudo .dotnet/tools/asa collect -f --overwrite --verbose --directories /sys --runid initialsys

EDIT: Installed Ubuntu Linux 20.04 to Oracle VirtualBox and more information was shown “Killed”:

When running without sys and proc directories, the file system collection finished in 15 mins: sudo ~/.dotnet/tools/asa collect -cfprsuFCl --overwrite --directories /bin^/boot^/dev^/etc^/home^/lib^/lib64^/lost+found^/media^/mnt^/opt^/root^/run^/sbin^/snap^/srv^/tmp^/usr^/var --runid excludeddirs

I also pushed a new change that will allow you to specifically exclude directories using the --skip-directories option so that you can explicitly provide / as the argument if you wish. So for example asa collect -f --directories / --skip-directories /proc,/sys,/mnt, to skip /proc and /sys (to prevent stalls) and /mnt (for example).

I updated the default file system collector to skip proc and sys on linux systems. New build should be coming out from the pipeline shortly if you want to give that a shot. The default argument should now scan every root directory other than /sys and /proc
