[Samba] Very slow write performance to RAID
We have a RAID set up as our main fileserver (running samba 3.0.33 on linux, CentOS 5). The main disk area is an XFS partition of about 8TB. I'm using iostat to monitor disk I/O since we've gotten complaints about speed and I'm noticing that when I write something to the samba share, the write speed is horrible. For a 15GB file it is reporting to finish in about 20 minutes. iostat reports very little write I/O...on the level of maybe 7 write i/o's every 5 seconds or so. If I were to read .5GB of data off of the samba share, it transfers quickly (and I see 300 reads/s through iostat)...which would be about normal. Any idea of why I'm getting such lousy write speed? If generate some data to write on the fileserver itself (not going through samba) I can get some decent numbers. With the command: dd if=/dev/zero of=/data/testfile bs=1024k count=1 I saw the 10GB write with a speed of 270MB/s, which is decent, so I'm not thinking there's anything wrong with the disk or raid controller. -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba

Re: [Samba] Integrating samba with existing AD
Hi all, I just suceed in configuring my new samba server. My users in Active Directory (Win2k3 R2) can successfully browse the shares they are able to view, write in their home directory, etc. But when trying to copy something inside one of the shared folder, I got an error message saying You are not allowed to edit this share. I searched and found that when I do change the owner of the shared folder to the user trying to copy something inside, it works ! Now the question is : how do I do to allow everyone to write in my shared folders ? This issue might be connected to another one I had. With this conf in nsswitch : /etc/nsswitch.conf passwd file ldap winbind group file ldap winbind shadow file ldap I have the following results : # wbinfo -n alfred S-1-5-21-725345543-507921405-1202660629-3262 SID_USER (1) # wbinfo -s S-1-5-21-725345543-507921405-1202660629-3262 WORKGROUP+alfred 1 # wbinfo -S S-1-5-21-725345543-507921405-1202660629-3262 502 # getent passwd |grep alfred alfred:*:2033:1500:alfred Test:/home/alfred:/bin/bash alfred:*:502:500:alfred Test:/home/WORKGROUP/alfred:/bin/false # wbinfo -U 2033 Could not convert uid 2033 to sid # wbinfo -U 502 S-1-5-21-725345543-507921405-1202660629-3262 And I cant do anything with my shares, whatever is the user I use to connect to them through explorer.

(I think the kernel doesn't understand them, so even if you created them, they wouldn't work). instead, you have ntfs hardlinks, and 'junctions', which are more limited but can be made to work -- like my 'Documents directory, is a separate Share I can mount it by //Bliss/Documents, and it will mount the user-specific share, for their doc dir, (same dir as //Bliss/home/law/Documents in above). I then can mount it at a rootdir -- something junctions seemed to have some requirement for)... Since things work 'flakey' (links are sometimes turned into files, so windows will try to access things via other means), I setup cross-user links for dirs I wanted shared -- don't share the appdirs! (it isn't that you can't, or that it won't work, but it isn't reliable, and you have to keep the apps on the different clients in sync if you don't or you have a workstation that doesn't read a profile in on login for some reason (I've had it happen more than once), but it *DOES* write the full profile out on logout), and if that workstation was recently reformatted and doesn't have all the same settings as the more current workstations, your 'unconfig'ed settings 'overwrite' your newer settings .. then when they login on the new workstations...they get settings that don't make sense or are months old or in a default config. Backups and keeping a recent lsm snapshot going in the background can allow quick recovery, it can still be a royal pain and certainly a nightmare on a larger site. The things that work well -- keeping my Desktop inside Documents, and keeping Documents on the network share -- that way it's never updated via the roaming profile. Still have some 'wayward', ill behaved apps (Adobe apps in particular, but also some personal backup SW, -- Thunderbird 3.x or above ... that download huge amounts of data into the user's local-roaming profile. (Adobe 2-3G, Backup SW .. varies, Tbird -- will download an entire network-share of email (IMAP) -- designed so network users could share 1 mail depot, into their appdir -- by
