We are using Digital Oceans block storage feature on our FreeBSD system.

When we add a new block storage we get:

da0 at vtscsi0 bus 0 scbus0 target 0 lun 1
da0: <DO Volume 1.5.> Fixed Direct Access SPC-3 SCSI device
da0: 300.000MB/s transfers
da0: Command Queueing enabled
da0: 5120MB (10485760 512 byte sectors)
da0 at vtscsi0 bus 0 scbus0 target 0 lun 1

and it works fine. We created a zpool and a zfs dataset. On the zpool we set: zpool set autoexpand=on tank

And then we resize the block storage disc on Digital Ocean.

Here is our problem

geom disk list does not pick up the change UNTIL we export the zpool. And we cannot resize the zpool until system has recognized the new size for the disc.

If we export the zpool it will correctly show the new size with geom disk list. But not until we have done so.

Now we can run zpool online -e tank da0 and the pool and its datasets will have the new size.

We have tried running camcontrol rescan da0but to no avail.

Is there any way to force a rescan to recognize the new disk size? Because now we have to export/unmount all the datasets, and that is not possible on an live envorionment.
