OK, you ran:

samba_upgradedns --dns-backend=BIND9_DLZ

when your inodes already matched (i.e. they where hardlinked), why ??

[root at linux01 local]# ls -ali /usr/local/samba/private/dns/sam.ldb.d
28188938 -rw-rw---- 2 root named 4247552 Nov 12 15:18 
DC=DOMAINDNSZONES,DC=ICSHK,DC=LOCAL.ldb
28188939 -rw-rw---- 2 root named 4247552 Oct 12 17:25 
DC=FORESTDNSZONES,DC=ICSHK,DC=LOCAL.ldb
28187344 -rw-rw---- 2 root named  421888 Nov 12 15:18 metadata.tdb

[root at linux01 local]# ls -ali /usr/local/samba/private/sam.ldb.d
28188938 -rw-rw---- 2 root named  4247552 Nov 12 15:18 
DC=DOMAINDNSZONES,DC=ICSHK,DC=LOCAL.ldb
28188939 -rw-rw---- 2 root named  4247552 Oct 12 17:25
