[lxc-users] zfs mountpoint disappeared

[Ingo Baab]

Hello All,

  I had a strange behaviour today and want to report it: I am using ZFS 
and the mountpoint
of my container "seemed to be disappeared", - but it was working 
(container worked..) so
mountpoint havt to exist - just mount did not show the mountpoint. I 
googled around and
found that I am not the first user finding this problem [1]. Is there 
more information for me
out there? My experience so far:

     zfs mount -a

reported:

     filesystem 'lxd/containers/webhosting1' is already mounted
     cannot mount 'lxd/containers/webhosting1': mountpoint or dataset is 
busy

I helpded myself with:

     lxc stop webhosting1
     zfs mount -a
     lxc start webhosting1

Is there more information what is happening here?
