`fsSize` returns empty array on some devices

Describe the bug
I am using systeminformation on my project inside a docker container, and some users (mostly Ubuntu 22-23) reported that fsSize returns an empty array.

To Reproduce
Hard to reproduce, as I can't really do so with my system either. It is a common error though, so you can look into MauriceNino/dashdot/issues/944 or MauriceNino/dashdot/issues/1032.

Current Output

Output gathered by user @SecOps-7, who is one of the users encountering this problem.

docker exec Dashdot df -kPT

Additional context

I tried parsing the output above with your code as well, but managed to do so just fine, so I am wondering which part is making the problems?

Example 
const _linux = true;
const _darwin = false;
const _freebsd = false;
const _openbsd = false;
const _netbsd = false;

function getmacOsFsType(fs) {
  if (!fs.startsWith('/')) { return 'NFS'; }
  const parts = fs.split('/');
  const fsShort = parts[parts.length - 1];
  const macOsDisksSingle = macOsDisks.filter(item => item.indexOf(fsShort) >= 0);
  if (macOsDisksSingle.length === 1 && macOsDisksSingle[0].indexOf('APFS') >= 0) { return 'APFS'; }
  return 'HFS';
}

function isLinuxTmpFs(fs) {
  const linuxTmpFileSystems = ['rootfs', 'unionfs', 'squashfs', 'cramfs', 'initrd', 'initramfs', 'devtmpfs', 'tmpfs', 'udev', 'devfs', 'specfs', 'type', 'appimaged'];
  let result = false;
  linuxTmpFileSystems.forEach(linuxFs => {
    if (fs.toLowerCase().indexOf(linuxFs) >= 0) { result = true; }
  });
  return result;
}

function filterLines(stdout) {
  let lines = stdout.toString().split('\n');
  lines.shift();
  if (stdout.toString().toLowerCase().indexOf('filesystem')) {
    let removeLines = 0;
    for (let i = 0; i < lines.length; i++) {
      if (lines[i] && lines[i].toLowerCase().startsWith('filesystem')) {
        removeLines = i;
      }
    }
    for (let i = 0; i < removeLines; i++) {
      lines.shift();
    }
  }
  return lines;
}

function parseDf(lines) {
  let data = [];
  lines.forEach(function (line) {
    if (line !== '') {
      line = line.replace(/ +/g, ' ').split(' ');
      if (line && ((line[0].startsWith('/')) || (line[6] && line[6] === '/') || (line[0].indexOf('/') > 0) || (line[0].indexOf(':') === 1) || !_darwin && !isLinuxTmpFs(line[1]))) {
        const fs = line[0];
        const fsType = ((_linux || _freebsd || _openbsd || _netbsd) ? line[1] : getmacOsFsType(line[0]));
        const size = parseInt(((_linux || _freebsd || _openbsd || _netbsd) ? line[2] : line[1])) * 1024;
        const used = parseInt(((_linux || _freebsd || _openbsd || _netbsd) ? line[3] : line[2])) * 1024;
        const available = parseInt(((_linux || _freebsd || _openbsd || _netbsd) ? line[4] : line[3])) * 1024;
        const use = parseFloat((100.0 * (used / (used + available))).toFixed(2));
        let rw = true;
        line.splice(0, (_linux || _freebsd || _openbsd || _netbsd) ? 6 : 5);
        const mount = line.join(' ');
        if (!data.find(el => (el.fs === fs && el.type === fsType))) {
          data.push({
            fs,
            type: fsType,
            size,
            used,
            available,
            use,
            mount,
            rw

Do you have any idea?

sebhildebrandt commented

@MauriceNino thank you! Will try to work on it this weekend. So basically, instead of returning what you provided in the example, we just get an empty array?

sebhildebrandt commented

@MauriceNino ... as your command getting the underlying information from the OS is different to what I am using in the library ... can you make sure to retrieve the following info an from the target machine:

export LC_ALL=C; df -lkPTx squashfs; unset LC_ALL

Thank you in advance.

MauriceNino commented

Thank you for looking into this! As far as I know some flag of those is not working in alpine linux. I think it was the l one, that's why I asked the user for the command I posted - thats the fallback provided in your code.

@SecOps-7 can you please test this by executing the command as well?

docker exec CONTAINER export LC_ALL=C; df -lkPTx squashfs; unset LC_ALL

and also try the following because I don't know if the above one works without a shell:

docker exec CONTAINER export sh -c "LC_ALL=C; df -lkPTx squashfs; unset LC_ALL"
MauriceNino commented

I have executed the command on my container - can only provide a screenshot as I am on my phone right now, but I expect this to happen for the other users as well:

Screenshot_20240122_234035_Chrome

But for clarification, fsSize works fine on my machine, so that should not be an issue. I can provide a log of any other commands on my machine/container as well so you have something to compare against.

sebhildebrandt commented

@MauriceNino I am a little confused ....

  • As you wrote in the first post, the OS is: Ubuntu 22 & 23
  • now we are talking of a alpine docker container ?

I just need to exactly know the environment to be able to reproduce the issue. Can you provide more details about the environment? If it is a docker container, it would also be interesting to know things like volume shares, ...

Thank you in advance.

MauriceNino commented

@sebhildebrandt Sorry I could have worded this better. What I meant is that all the users who have had problems with this, had Ubuntu 22 or 23 as a host, but all had the alpine docker container running that my application is running in.

Unfortunately I don't know what volume shares are, but maybe @SecOps-7 can answer that question?

I don't have any volumes shared on the Ubuntu host itself. I do however have all my NAS Media folders mounted via cifs.
Apart from that I believe I have a symlink or two somewhere. Not sure if this is what you are looking for.

sudo docker exec Dashdot sh -c "export LC_ALL=C; df -lkPTx squashfs; unset LC_ALL"

@MauriceNino seems df does not accept the -l or -x operators...

I got the below errors and then was able to run it successfully after removing l and x.
Unfortunately I then get the error that df was unable to find the squashfs mount point.

sudo docker exec Dashdot sh -c "export LC_ALL=C; df -lkPTx squashfs; unset LC_ALL"

df: unrecognized option: l

sudo docker exec Dashdot sh -c "export LC_ALL=C; df -kPTx squashfs; unset LC_ALL"

df: unrecognized option: x

sudo docker exec Dashdot sh -c "export LC_ALL=C; df -kPT squashfs; unset LC_ALL"

The command executes fine with the all the operators on my local Ubuntu.
Seems its just having issues running inside the docker container.

MauriceNino commented

Yeah, that should be fine - that's what the fallback is for, right @sebhildebrandt ?
And df -kPT should work fine inside the container.

sebhildebrandt commented

@MauriceNino right, but inside a container I get just the result inside of the container (basically the isolated environment containers are made for) and not the result of the host machine, right?

MauriceNino commented

@sebhildebrandt Yes, but with my application, I instruct my users to mount the entire host path into the container at /mnt/host. That's how systeminformation is able to read the correct data via fsSize.

For example, here is the output of fsSize on my instance of dashdot (inside the docker container, but omitted all the squashfs ones for clarity):

Hi. dashdot/issues/1032 has updates. After upgrade latest system packages problem resolved. But I can't explain which package. Also attached my log of updates included in fedora 39

sebhildebrandt commented

@MauriceNino ... concerning the last message here: so we can close this issue??

djwinston commented

Not yet. Author of issue after next upgrade again has the problem. We try to investigate packages version on Ubuntu and Fedora

It's related only for dashdot issue 1032, not for 944

MauriceNino commented

@sebhildebrandt No, unfortunately, it still seems to me like there are some issues that could be resolved.

The output of fsSize that I posted in the issue does not match up with the output of docker exec Dashdot df -kPT, which to me indicates that there is maybe some permissions problem, or maybe it parses the export LC_ALL=C; df -lkPTx squashfs; unset LC_ALL wrong and then doesn't fall back to the df -kPT. Honestly, I have no clue, but the issue still seems to persist.

If you have already checked it and there seems to be nothing wrong with systeminformation, you can of course just close this issue for now and wait for users to troubleshoot in MauriceNino/dashdot#1032 - maybe we can figure it out together and see if something needs to be changed here. If that is the case, I will report back. For now, I personally can't really tell where the problem lies.

Thank you for taking your time with this though :)

For node alpine containers the only solution that I have found for this is to install coreutils:

apk add coreutils

The reason is the following:

In the file lib/filesystem.js, the default command used in alpine is:

export LC_ALL=C; df -lkPTx squashfs; unset LC_ALL

This fails because busybox df doesn't support the l option. This results in the fallback command running:

df -kPT

This command succeeds but also can include some content in stderr (even though there are valid entries in stdout).

Specifically the content in stderr is about the paths like /sys/kernel/xxx not existing.

However because there is a difference in how the output is handled in the fallback command, if there is any content in stderr, the following lines never execute:

              if (!error) {
                let lines = filterLines(stdout);
                data = parseDf(lines);
              }

Because of this the data variable that is passed as the result to the callback or the resolve of the Promise is an empty array.
