Broken File System Usage graph for one (but only one!) volume

[mikeage]

Describe the bug

After upgrading to the latest OMV (which includes #1806), I have a broken graph for one of my volumes. The only thing different about this one, that I can see, is that it's a BTRFS volume with multiple devices, as opposed to just one.

To Reproduce

Steps to reproduce the behavior:

1. Go to Diagnostics -> Performance Statistics -> File System Usage
2. Choose volume 9900c9f3-6ac9-4791-a4a9-cb3f9c140f53 (obviously only on mine!)
3. See broken graph (attached)
4. I tried the regenerate button, but it didn't change anything. I don't know where the logs are; there was nothing in the main journal (sudo journalctl -f)

Expected behavior

Proper graph, like the rest of them Screenshots

After upgrading to the latest OMV (which includes https://github.com/openmediavault/openmediavault/pull/1806), I have a broken graph for one of my volumes.

This means, before there was no problem? I can't really imagine that because the change doesn't really do anything different.

Please post the output of

# omv-rpc -u admin 'FileSystemMgmt' 'enumerateMountedFilesystems' '{"includeroot": true}' | jq
# omv-rpc -u admin 'CollectdDisk' 'enumerate' | jq
# ls -alh /var/lib/rrdcached/db/

[mikeage]

Before, there was some inconsistency in how the graph was displayed, hence issue #1805 :-)

From what I have seen everything is ok, all files exist and I do not see any differences in the data received by the RPC to populate the graph pages.

Have you tried to clear the browser cache? Maybe the browser is caching parts of the old page and therefore does not display the expected graphs?

[mikeage]

Clearing cache or trying in incognito didn't help.

[votdev]

Can you please go to the tab with the graph missing icon, click RMB and chhose Copy image address or Copy graphic address (i have a localized Firefox, so i don't know the exact english menu naming). The result should look like

http://omv7box.local/download.php?service=Rrd&method=getGraph&params=%7B%22kind%22:%22df-srv-dev-disk-by-uuid-0edf9eda-235c-43e3-ac73-f651cf490d6a%22,%22period%22:%22hour%22%7D&time=1724181774

[votdev]

How is it possible that the mount point of /dev/disk/by-uuid/9900c9f3-6ac9-4791-a4a9-cb3f9c140f53 is /export/storage. Looks like a NFS bind mount IMO.

[votdev]

Please post the content of the file /etc/fstab and the command output of mount and finally the output of omv-confdbadm read --prettify conf.system.filesystem.mountpoint.

In case it's not immediately obvious, I did something slightly non-standard (but still supported) with my shares: instead of creating shared folders called "foo" at /srv/dev-disk-whatever/foo, I created the share named "foo" with a relative path of "/", so the entire drive is mounted for NFS.

I think that's the problem.

Can you please post the output of findmnt --noheadings --raw --nofsroot --output SOURCE,TARGET,UUID.

[votdev]

The problem is that the output will look like this then:

/dev/sda /srv/dev-disk-by-uuid-0edf9eda-235c-43e3-ac73-f651cf490d6a 0edf9eda-235c-43e3-ac73-f651cf490d6a
/dev/sda /export/nfs 0edf9eda-235c-43e3-ac73-f651cf490d6a

Now it depends on the order. I assume in your case the /export/xxx entry is the first in the list and that's why this mount point is chosen. First come, first served.

[mikeage]

Bingo!

As an alternative, the command line findmnt --noheadings --raw --output SOURCE,TARGET,UUID --fstab --evaluate could be used, in which the bind-mount has no file system UUID, which could be used for filtering. The disadvantage is that the original functionality of the implementation to determine the mount point for each file system is lost. With --fstab only those file systems would be considered which are in /etc/fstab. Therefore I think this solution is no longer necessary.

# findmnt --noheadings --raw --output SOURCE,TARGET,UUID --fstab --evaluate
/dev/vda1 / 386c28c2-ad19-4bbb-8323-fc96866454db

/srv/dev-disk-by-uuid-0edf9eda-235c-43e3-ac73-f651cf490d6a/ /export/nfs 

[votdev]

It seems findmnt make the output arbitrary and there is no possibility to modify the output by an option.

[votdev]

I don't think the problem can be solved from this direction. Maybe I should have a look at how the RPC is implemented that is used to create the data for the graph URL. As far as I have seen, an RPC is called that iterates over the configured database objects of the mount points. However, the database objects contain the mount point; perhaps this should be returned instead of the dynamically determined one.

Thanks!
