Here is what i've done: 1. Join the new Samba4.0.0beta8 server "PDC2" to the old Samba4.0.0alpha server "PDC" with: samba-tool domain join mydomain.lan DC -Uadministrator --realm=mydomain.lan --dns-backend=none 2. Copy the file based Bind9 configuration from /etc/bind of "PDC" to "PDC2" 3. Disconnect "PDC" from the network 4. run samba_upgradedns on "PDC2" to get BIND_DLZ to work 5. Configure Bind9 to use Samba4/BIND_DLZ What works: A. I can browse with Microsoft RSAT through the Active Directory and can edit or create users and so on B. I can create and modify DNS-entries from the DNS-Tool of MS RSAT C. I can join a computer to "PDC2" when logging on with "administrator@mydomain" What does not work: A. I can't join a computer to "PDC2"

How do the clients get their ipaddresses? are they fixed or supplied by DHCP? what nameserver are they pointed at? does this nameserver know about hh32? What does 'ipconfig /all' (run in a dos box on the client) give?

[Samba] suggestion for filesystem or general performance optimization
Hi, recently I noticed, that we have some performance issues regarding our central samba fileserver. Red Hat EL 5.8, samba3x-3.5.10-0.109. Doing a rsync, scp or accessing a share from a client and copy large files (e.g. 3 GB ISO), I do get a read / write average about 60 to 90 MB/sec. So LAN and general hardware can work at max. lan speed. But copying or syncing small files, e.g. user profiles etc. or doing a backup of the smaller files lets drop the average performance to 10 MB/Sec or less :( We use ext3 (noatime), the storage is connected by iscsi, it is a sun storage with sas harddisk. All suggestions so far: migrate to ext4 and good luck :) I read a couple of filesystem comparisons and ext4 looks like the best option, but what else could I do or expect? Locking? Limits ... blocksizes, more RAM (4GB installed), we have about 600GB of user data. so not really much... Thanks for any suggestion or hint . Regards .
