[Samba] [questions] aio settings in smb.conf and compile options
hi, i just have some questions about specific (uncommon) compile options and aio-settings in smb.conf: Asynchronous IO Support === Experimental support for async IO has been added to smbd for certain platforms. To enable this new feature, Samba must be compiled to include the --with-aio-support configure option. In addition, the aio read size and aio write size to non-zero values. See the smb.conf(5) man page for more details on these settings. unfortunately i can´t find any documentation about this although it has been in the code since a while. Compile Options - what means/provides (more detailed please) ... ? == --with-cluster-support --with-automount BIG THX!! btw: what happened to john? is he still an active member of the samba team, ´cause i did not see any posts on the list for example?!?! -- Michael Gasch Max Planck Institute for Evolutionary Anthropology Department of Human Evolution (IT Staff) Deutscher Platz 6 D-04103 Leipzig Germany Phone: 49 (0)341 - 3550 137 49 (0)341 - 3550 374 Fax: 49 (0)341 - 3550 399 -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/listinfo/samba

If you are interested in the current (VERY experimental) state of affairs look at the vl-messaging temporary svn branch. The idea is that with a clustered file system like GFS, OCFS, GPFS or some others you will be able to share the same file space transparently from all cluster nodes and have locking working properly. Right now we are discussing and designing ways to make the experimental support for that robust so that we don't depend on a single point of failure.

See the smb.conf(5) man page for more details on these settings. unfortunately i can´t find any documentation about this although it has been in the code since a while. Compile with --with-aio-support to enable this. Look in the source code smbd/aio.c. I haven't documented the parameters yet (thanks for the reminder, I'll try and get this done soon). They are : aio read size = bytes aio write size = bytes aio write behind = true|false Any reads/writes over bytes will be done via aio. It hasn't been turned on fully yet as some Linux's fake aio support using pthreads which makes smbd *slower* :-(. Kernel support for aio is still a little flakey - I need to spend some more time testing it. The biggest disappointment is that there seems to be no way to get Windows clients to pipeline more than one read or write on the wire. They simply stick with a request/response pair. smbclient will pipeline reads/writes though. Not sure about cifsfs - Stevef, any comments (or I'll just go look in the code :-). aio write behind was an attempt to see if we could fool Windows clients into pipelining. If set true, smbd *lies* about writes being done (and assumes the aio will always succeed) and returns early success to the client. Don't set this if you have *any* interest in your data :-). Compile Options - what means/provides (more detailed please) ... ? == --with-cluster-support --with-automount Volker knows more about these. BIG THX!! btw: what happened to john? is he still an active member of the samba team, ´cause i did not see any posts on the list for example?!?! John is now working at AMD, who keep him rather busy on his day job :-). He still wants to keep active but it's easier said than done :-).

thx to jeremy and volker for your quick and detailed response (as usual)... if someone has any explanation for --with-automount i would appreciate this as well :) i'm just trying to explore samba features i recognized but often can't interpret there meaning. @jeremy looks like you took over john's part since you seem to be more present on the list than before :-D (could be too much imagition, though) cheerz -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/listinfo/samba

IIRC --with-automount should automount the home directory when a user steps in. Simo.

I'm afraid, this is not what it does. man smb.conf says %N the name of your NIS home directory server. This is obtained from your NIS auto.map entry. If you have not compiled Samba with the --with-automount option then this value will be the same as %. Looking at the code it also needs the undocumented parameter 'nis home map' to be true.

Right, reading the code it also looks up where your NIS home directory is using yp calls when %p is used. This configure option name is really misleading imo.
