Description

I've seen this as far back as Nexenta Core Platform 3, but I was shocked to see it on SmartOS:

# uname -a
SunOS fs-chassis-01 5.11 joyent_20150430T082110Z i86pc i386 i86pc

Steps to reproduce:¶

# cat /etc/dfs/sharetab 
# zfs create -o mountpoint=/shareme zones/shareme
# zfs create zones/shareme/child1
# zfs create zones/shareme/child2
# zfs create zones/shareme/child3
# zfs set sharenfs=root=foo.example.com,root=bar.example.com zones/shareme
# cat /etc/dfs/sharetab 
/shareme/child2 -       nfs     sec=sys,root=foo.example.com:bar.example.com:foo.example.com:bar.example.com:foo.example.com:bar.example.com:foo.example.com:bar.example.com
/shareme/child1 -       nfs     sec=sys,root=foo.example.com:bar.example.com:foo.example.com:bar.example.com:foo.example.com:bar.example.com:foo.example.com:bar.example.com
/shareme        -       nfs     sec=sys,root=foo.example.com:bar.example.com:foo.example.com:bar.example.com:foo.example.com:bar.example.com:foo.example.com:bar.example.com
/shareme/child3 -       nfs     sec=sys,root=foo.example.com:bar.example.com:foo.example.com:bar.example.com:foo.example.com:bar.example.com:foo.example.com:bar.example.com

Expected Results:¶

# cat /etc/dfs/sharetab 
# zfs create -o mountpoint=/shareme zones/shareme
# zfs create zones/shareme/child1
# zfs create zones/shareme/child2
# zfs create zones/shareme/child3
# zfs set sharenfs=root=foo.example.com,root=bar.example.com zones/shareme
# cat /etc/dfs/sharetab 
/shareme        -       nfs     sec=sys,root=foo.example.com:bar.example.com
/shareme/child1 -       nfs     sec=sys,root=foo.example.com:bar.example.com
/shareme/child2 -       nfs     sec=sys,root=foo.example.com:bar.example.com
/shareme/child3 -       nfs     sec=sys,root=foo.example.com:bar.example.com

Workaround:¶

Use "root=foo:bar" rather than "root=foo,root=bar"

# zfs set sharenfs=root=foo.example.com:bar.example.com zones/shareme
# cat /etc/dfs/sharetab 
/shareme        -       nfs     sec=sys,root=foo.example.com:bar.example.com
/shareme/child1 -       nfs     sec=sys,root=foo.example.com:bar.example.com
/shareme/child2 -       nfs     sec=sys,root=foo.example.com:bar.example.com
/shareme/child3 -       nfs     sec=sys,root=foo.example.com:bar.example.com
