[Solved] Mount point not found in fstab errors in logfile

[HanSooloo]

I have setup JDownloader2 in headless mode running inside a FreeNAS 9.10 jail with OpenJDK 8.

Every time (I think) a file gets done downloading, I see the below error messages (with no ill effect, downloads complete successfully and extract OK).

What is JD trying to find in fstab that it complains about?

Below is the mount command results:

root@JDownloader:/usr/local/JDownloader # mount
tank/jails/JDownloader on / (zfs, local, noatime, nfsv4acls)

And a weird /etc/fstab, i.e., nothing!

root@JDownloader:/usr/local/JDownloader # cat /etc/fstab
root@JDownloader:/usr/local/JDownloader #

This being inside a FreeBSD jail, wondering if the normal mount related files/info is simply not there.

I guess it is because of FreeBSD jail has no own fstab
Try to disable
Settings-Advanced Settings-GeneralSettings.freespacecheckenabled

Or try out solution from here
github.com/elastic/elasticsearch/issues/12018

it seems that setting the jail’s enforce_statfs property to 1 allows
