Hi there, are you still interested in creating a cluefs package? Because I am interesting in using it in my application :)
If you are ok with that, I will start working on it in my fork ( https://github.com/rfjakob/cluefs ) and send a pull request once it is ready.
hi,
I haven't looked into cluefs traces' event format but I suppose it would be great to use chromium traces' format so these traces could be analyzed with the nice trace-viewer they've developed:
https://www.chromium.org/developers/how-tos/trace-event-profiling-tool
https://github.com/google/trace-viewer
trace-event format
Go runtime is now using this when launched in profiling/tracing mode and it's a breeze to inspect and debug performance profiles.
Renaming a file leaves the renamed file in a broken state that is only fixed by unmounting and mounting again:
$ echo foo > foo.txt
$ ls -l
-rw-rw-r--. 1 jakob jakob 4 7. Sep 20:58 foo.txt
$ mv foo.txt bar.txt
$ ls -l
----------. 0 root root 0 1. Jan 1970 bar.txt
$ rm bar.txt
rm: cannot remove ‘bar.txt’: Input/output error
When using VIM on CentOS 7.5, whenever I save a file, I see this error:
"/tmp/trace/nanofile.txt"
"/tmp/trace/nanofile.txt" E667: Fsync failed
WARNING: Original file may be lost or damaged
don't quit the editor until the file is successfully written!
