extremely low performance on Samba 4.2.14-Debian
Hai, Ok, so you have 3 the same machines and only one is slow. Thats important info. Did anything special happen with this server. For example 2 servers got a new install and this one had an upgrade (or sort of upgrade) from the "old" server? Or you configured the new server in an other (ad site) and moved it to the new location. In tring to figure out, where what happend, so we

extremely low performance on Samba 4.2.14-Debian
Hi everyone, here's my problem: I have a fast server (dual Xeon E5-2620, 64 GB RAM) with a fast RAID array (24 disks, RAID-6, more than 2GB/s read/write local performance, XFS filesystem) and fast network : dual 10GigE (myri10g) and 40GigE (i40e). It's running Debian 8.11, tried various kernel versions (currently 4.4.x, but 4.9 isn't any better). It's slow as dead snails in

extremely low performance on Samba 4.2.14-Debian
Hai, I got a personal notice of a user, which server was running 4.2.14 (debian jessie), he only got 10-14Mb/s, after upgrading to my 4.6.6 package (now 4.6.7, he is now getting the full gigabit connection speed. Now if you dont want to upgrade you can try set the nic speed in smb.conf. ( man smb.conf ) interface[;key1=value1[,key2=value2[...]]] Known keys are speed, capability, and

poor samba performance with many smaller files
Hi, I need to to open existing readonly files. Yes you are right, not the open call takes the time, but stat() system call. I looked at aio_pthread source, the lines which needs to be removed to make it work are just the lines which tests for O_CREAT|O_EXCL? What problems can cause such solution for readonly share?

Configuring aio_pthread
I'm trying to learn more about samba by experimenting with samba on FreeNAS. This involves a certain amount of reading how default smb4.conf parameters are set in FreeNAS and then reading the manpages for those parameters. Async I/O is implemented in samba in freenas via the aio_pthread VFS module. The manpage for vfs_aio_pthread states: "the smb.conf parameters aio read size and aio

aio-pthread, conflicting param info
In the vfs pages for aio_pthread, it gives as an example for aio read/write size, 1024 for each and states an "appropriate" value must be set. Byt in smb.conf it states that the only reasonable values are 0 or 1 (also that there's a default = 1 so no value need be given explicitly). Which of these is correct? Thanks, Stilez

aio_pthread on Debian?
Hello list, I am looking to enable samba aio on my Wheezy test box (I have version 4.1.17 from back ports). The output of smbd -b shows that the stable packages for my distro are not compiled using --with-aio-support. It appears that without recompiling I can use vfs objects = aio_pthread to achieve a similar effect? I'm aware that this somewhat dips into Debian specifics, but I figured

Issues with mounting Samba shares after update
Actually it isn't part of AD at all. We are using FreeIPA and Samba. We just finally figured this out with the help of some folks at Red Hat. It turned out there was a bug in one of the libraries that came along with sssd (sssd-libwbclient I believe). Their suggestion to use winbind and the version of the same library that came with it seems to have solved our problem instantly. It

Old Samba 3.x server as a Samba 4 AD member.
Hi everyone, we plan on setting up a Samba 4.x based AD. We have a couple of ancient to old systems running samba 3.0.24 to 3.5.7 and 3.6.24. Is there any problem to integrate those old systems as member of a Samba 4-driven AD? -- ------------------------------------------------------------------------ Emmanuel Florac | Direction technique | Intellique

Moving users from a Samba 3.6 to 4.9 (tdb)
Hello, I have an old 3.6 server to be replaced with a new 4.9 one. They are standalone, using tdbsam backend. I copied system users and group, then /var/lib/samba/*.tdb from the old to the new one. However, obviously the newer samba absolutely doesn't care about my old user database. "pdbedit -L" returns nothing on the new server. Is there some upgrade step I'm missing here?
