[lxc-users] lxd start very slow and error msg="zfs mount failed" driver=storage/zfs output="cannot mount 'lxd/containers/fw-manuel': filesystem already mounted\n"

[AIRIS MENU]

Hi,


LXD container start correctly after 11 seconds. I'm using Ubuntu 14.04 with a second disk with ZFS for containers and in /var/log/lxd/lxd.log appear error messages:


t=2016-12-14T12:49:31+0100 lvl=info msg="Starting container" name=fw-manuel action=start created=2016-12-06T21:39:55+0000 ephemeral=false used=2016-12-13T23:19:34+0000 stateful=false
t=2016-12-14T12:49:41+0100 lvl=eror msg="zfs mount failed" driver=storage/zfs output="cannot mount 'lxd/containers/fw-manuel': filesystem already mounted\n"
t=2016-12-14T12:49:42+0100 lvl=info msg="Started container" name=fw-manuel action=start created=2016-12-06T21:39:55+0000 ephemeral=false used=2016-12-13T23:19:34+0000 stateful=false

The zfs pool seems to be ok:
manuel at examenes:~$ sudo zpool status
[sudo] password for manuel:
  pool: lxd
 state: ONLINE
  scan: none requested
config:

    NAME        STATE     READ WRITE CKSUM
    lxd         ONLINE       0     0     0
      sdb       ONLINE       0     0     0

errors: No known data errors
And container mount correctly:
manuel at examenes:~$ sudo zfs list

Running Ubuntu 14.04 with lxd 2.6.2 and ubuntu-zfs (from ppa:zfs-native/stable). An identical container in another host running Ubuntu 16.04 with zfs starts in 1 second without errors in /var/log/lxd/lxd.log .

Any ideas?
Thanks in advance
Manuel Glez.
