[LTP] Running LTP on new filesystems

[LTP] Running LTP on new filesystems

[Akshatha Gangadharaiah]

Hi everyone,

I am trying to run LTP on a new filesystem and am stuck in figuring out the right way to do this.

Specifically, if I have mounted my file system at /mnt/new-fs, I want to use this directory as mount point for all the filesystem tests.
I tried running by specifying this as the  -d TMPDIR  option ( -d /mnt/new-fs in runltp ) but I am not sure if this is the right way.

I don’t see any specific instructions on how to run LTP on new filesystems.
It will be a great help if someone points out the right way to do this or any documentation that might help.

Thanks for your time and patience,

Regards,
Akshatha G

This is exactly what I would have done. Most of the testcases uses
TMPDIR as a base for any temporary files and so all fs related syscalls
will end up in the right filesystem code.

There are a few testscases that use a device for testing and make
filesystem there. You have to export *FS_DEV_TYPE env variables (see
runltp -h), otherwise these default to ext2.

Sorry, we are a bit underdocumented in that area.
