I am running a FreeBSD 11.1 system with ZFS and jails and I mount a file system on my storage pool (/storage/cloud) into the jail (/jails/cloud/storage) via nullfs, and that works fine for what the jail does. However I just noticed that outside the jail, I can only see the mount points of the file system children, but not the contents.
For example if I do: ls -la /storage/cloud/* (As root) then nothing shows up, but they are present inside the jail. Even if I stop the jail, they still are not present outside the jail. I just tried disabling jails in /etc/rc.conf and rebooting the system and EVEN THEN the files do not reappear outside the jail in their original location, yet zfs list reports the space being used. But if I then (without rebooting) enable the jail, the files show up in the nullfs-mounted location inside the jail! As an experiment, I tried creating /mnt/test and /mnt/test2 and creates a folder and a few files in test, and then nullfs-mounted it onto test2, and I could then see the files in both locations. Does anybody know what might be causing this? The fact that my data stays hidden after a reboot is rather worrisome. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[email protected]"
