Bug with cAdvisor on ZFS/Ubuntu about dockprom HOT 7 CLOSED

this works-- definitely a good fix

from dockprom.

However after I did this, my containers started to throw errors from time to time when they are stopped or started:

ERROR: for php_con  driver "zfs" failed to remove root filesystem for
ebfefd01c4ac80883e62229f0edbd02d0e9b1b250d997a5fdc68783a648bd730:

Same issue here. Does not play well with ZFS.

This isn't a bug, if you're running ZFS as your storage backend all you need to is include the devices key like @kekcleader mentioned above.

 devices:
   - /dev/zfs:/dev/zfs

from dockprom.

So should it stop throwing those errors if I just add this line?

 devices:
   - /dev/zfs:/dev/zfs

from dockprom.

The error you are experiencing above isn't an issue with cAdvisor, ZFS can't remove a dataset because it's busy. This could be occurring for a number of different reasons.

What you have done above, including the device means that the ZFS driver will be loaded appropriately and isn't related to the error.

@kekcleader I'm going to close this due to inactivity, if you have a specific problem that persists please open another issue.
