Linux за българи: Форуми

Хора не знам защо се получава така но самбата ми качва load average на сървъра до 4 при трансфер което не е нормално. Сървъра е P4 2.4 GHz, 1.2GB RAM и това не е нормално. Файловата система е xfs ако това има значение. Дистрибуцията е Gentoo и се упдейтва постоянно до последен stable release. Ето го и smb.conf:

# This is the main Samba configuration file. You should read the # smb.conf(5) manual page in order to understand the options listed # here. Samba has a huge number of configurable options (perhaps too # many!) most of which are not shown in this example # # For a step to step guide on installing, configuring and using samba, # read the Samba-HOWTO-Collection. This may be obtained from: #  http://www.samba.org/samba/docs/Samba-HOWTO-Collection.pdf # # Many working examples of smb.conf files can be found in the # Samba-Guide which is generated daily and can be downloaded from: #  http://www.samba.org/samba/docs/Samba-Guide.pdf # # Any line which starts with a; (semi-colon) or a # (hash) # is a comment and is ignored. In this example we will use a # # for commentry and a; for parts of the config file that you # may wish to enable # # NOTE: Whenever you modify this file you should run the command "testparm" # to check that you have not made any basic syntactic errors. # #======================= Global Settings ===================================== [global] # 1. Server Naming Options: # workgroup = NT-Domain-Name or Workgroup-Name # netbios name is the name you will see in "Network Neighbourhood", # but defaults to your hostname ;  netbios name = <name_of_this_server> # server string is the equivalent of the NT Description field server string = TheMachine # 2. Printing Options: # CHANGES TO ENABLE PRINTING ON ALL CUPS PRINTERS IN THE NETWORK # if you want to automatically load your printer list rather # than setting them up individually then you'll need this printcap name = cups # It should not be necessary to spell out the print system type unless # yours is non-standard. Currently supported print systems include: # bsd, sysv, plp, lprng, aix, hpux, qnx, cups printing = cups # 3. Logging Options: # this tells Samba to use a separate log file for each machine # that connects log file = /var/log/samba/log.%m # Put a capping on the size of the log files (in Kb). max log size = 50 # Set the log (verbosity) level (0 <= log level <= 10) ; log level = 3 # 4. Security and Domain Membership Options: # This option is important for security. It allows you to restrict # connections to machines which are on your local network.

Name Resolution Options: # All NetBIOS names must be resolved to IP Addresses # 'Name Resolve Order' allows the named resolution mechanism to be specified # the default order is "host lmhosts wins bcast". "host" means use the unix # system gethostbyname() function call that will use either /etc/hosts OR # DNS or NIS depending on the settings of /etc/host.config, /etc/nsswitch.conf # and the /etc/resolv.conf file. "host" therefore is system configuration # dependant. This parameter is most often of use to prevent DNS lookups # in order to resolve NetBIOS names to IP Addresses. Use with care! # The example below excludes use of name resolution for machines that are NOT # on the local network segment # - OR - are not deliberately to be known via lmhosts or via WINS. ; name resolve order = wins host lmhosts bcast # Windows Internet Name Serving Support Section: # WINS Support - Tells the NMBD component of Samba to enable it's WINS Server ;   wins support = yes # WINS Server - Tells the NMBD components of Samba to be a WINS Client #       Note: Samba can be either a WINS Server, or a WINS Client, but NOT both ;   wins server = w.x.y.z # WINS Proxy - Tells Samba to answer name resolution queries on # behalf of a non WINS capable client, for this to work there must be # at least one  WINS Server on the network. The default is NO. ;   wins proxy = yes # DNS Proxy - tells Samba whether or not to try to resolve NetBIOS names # via DNS nslookups.

Моля Ви помагайте ако имате някакви идеи.

Първо като гледам конфигурацията ми изглежда малко омотана ама кво да се прави. Явно имаш windowski машини които са боднати в домейн управляван от самбата.

Общи насоки:
 * махни всичко излишно и го спри изрично - winlogon, domainlogon, printing
 * сложи си име на машината ... няма да повярваш колко помага за някои работи
 * монтирай си файловите системи с правилни опции (noatime върши чудеса)
 * ако XFS-а е пълен над 70% става доста бавен на определени моменти.
 * XFS като цяло се държи бавно (за сметка на това е доста стабилен)
 * намери си от някъде книжката SAMBA 3 - има много истина в нея.

Книжката за SAMBA - 3 мога да ти я пратя на CHM, само напиши едно PM с емайл (5,5 МБ)
