Dotaz: Server zamrza po nekolika hodinach.

[Lemmy]

Ahoj, mam problem se serverem. Jedna se o IBM Netvista s procesorem Pentium 4 2.40GHz, 256 MB ram a pevnym diskem IBM/Hitachi Deskstar GXP-180 40 GB. PC driv slouzilo jako pracovni stanice s winXP.

Na server jsem nainstaloval Centos 5. Server by mel slouzit jako zalozni firewall, takze v teto chvili na nem v podstate nic nebezi.

Problem je v tom, ze server zacne po nekolika hodinach provozu zamrzat. Nektere prikazy se provadeji nesmyslne dlouho(ls). Jine prikazy nezobrazi zadny vystup (top) a server nejde restartovat zadnym prikazem (shutdown -r now, reboot, init 6).

V systemovem logu jsem nic podezreleho nenasel. Jedina zvlastni vec je vypis procesu po spusteni prikazu shutdown -r now:

ps -A
.
3659 ?        00:00:00 udevd
 3660 ?        00:00:00 udevd
 3672 ?        00:00:00 udev_run_devd defunct
 3676 ?        00:00:00 udev_run_hotplu defunct
.

Kdyz server restartuji rucne, tak po restartu vse zase nejakou dobu funguje tak jak ma.

Prikladam seznam bezicich procesu:

Viděl bych to na problém s HW a diagnostiku bych začal memtestem.

[Lemmy]

Bohuzel ten server je v zahranici, takze nemam moznost spustit memtest z live cd. Existuje nejaky memtest, ktery se necha spustit primo z bashe?

Zvlastni je, ze stejny problem mam na trech serverch a vsechny maji stejny hw.

Diky za reakci.

[svaca]

pokud to nebude samotnym Centos (jadro a pod) tak to muze byt i napajenim, treba je nejaky problem na UPS, ci neco podobneho... Memtest zkouset nemusis, kdyz ma pocitac problem s pameti, programy generuji chyby a padaji a nebo se restartuje stroj sam, ale nezamrza .... Pokud pocitac zamrza a je to hardware pricinou, vetsinou se jedna o CPU, sbernice a pridavne karty ...

[Marian Krucina]

Primo z bashe ne, ale muzes ho nainstalovat od systemu, nastavit v grubu na vyhozi, a reboot. Tady moje predstavivost konci :(

A co dmesg? Nehlasi zadne problemy?

Diky za reakci.

Zdravim!

Tohle prilis nepomuze. Spise by se hodilo, jestli je moznost vyfotit vystup obrazovky v dobe zakousnuti. Urcite tam kernel vyplivne co se mu stalo, ale bohuzel nikde jinde to neni k dohledani, takze tam musi prijit bud linuxar a nebo lamka s fotakem

[Lemmy]

To asi bude problem, protoze server se nachazi v zahranici.

[Shadow]

Existuje nejaky memtest, ktery se necha spustit primo z bashe?

Existuje, memtester.

[Shadow]

Ještě mě napadly dvě věci. Mohl by to být nějaký splašený proces, co žere paměť nebo CPU čas (popř. obojí). Když začne opět docházet k problémům, zkontroloval bych volnou paměť příkazem free a mrknul se na to, jak moc aktivní jsou procesy. Tady dobře poslouží top nebo htop.

Druhý nápad je asi úplná blbost, ale co takhle zkusit vypnout udev a zjistit, jestli se problém náhodou netýká jeho samotného?

[Shadow]

Pardon, říkal jste, že vám top nezobrazí žádný výstup, takže místo toho zkuste:

ps aux

Nikde nemuzu najit jak vypnout udev. Neni to v RHELu automount ?

Diky za reakci.

[Shadow]

Žádný splašený proces nevidím. Udev by měl jít dočasně vypnout takto:

/etc/init.d/udev stop

Nebo také takto:

service udev stop

Permanentně vypnout by měl jít pomocí chkconfig. Ale to bych prozatím nedělal.

[Lemmy]

Tak zadnou takovou sluzbu nemam:

[root@default_dde ~]# chkconfig udev off
error reading information on service udev: No such file or directory

[Shadow]

Démon udev se dá vyřadit ručně. Pokud máte možnost počítač vzdáleně restartovat i bez ssh (kdyby něco), pak zkuste:

kill -15 `ps aux | grep udevd | awk '{print $2}'`

[Lemmy]

Tak bohuzel ani po ukonceni udevd se situace nezmenila. Server se chova porad stejne a nejde vzdalene restartovat. nezbyva nez pockat do pondeli, kdy ho otoci kolega rucne. A uvidime po restartu.

Mozne ze by mohlo pomoct toto: http://www.fedoraforum.org/forum/printthread.php?t=139648&page=2&pp=80

Obzvlast posledni prispevek.

Diky za reakce.

[svaca]

Jak rikam, pokud nezmenis nejaky HW, dle meho nazoru napajeni a nebo CPU nikam se asi nehnes ...

[Lemmy]

HW bohuzel nevymenim. Servery jsou v zahranici. Problem je totozny u dvou HW stejnych serveru. Oba drive slouzily jako stanice s winXP, kde se chovaly naprosto standardne.

Diky za reakci.

[svaca]

Mam zkusenost, ze chovani na Windows je UPLNE jine, nez na linuxu, priklad: Kdyz to prezenu s prekatkovanym procesorem a testuji to pomoci prime95 tak ve windows CASTO zmrzne cele PC a v linuxu pouze spadne aplikace ...

Kdyz pak zase je problem na pametech, tak ve Windows se pocitac resetuje ... V linuxu VETSINOU zase spadne aplikace a nebo padaji jaderne moduly a veobecne padaji veci okolo jadra ....

[Shadow]

Ještě jedna věc. Předpokládám, že tenhle výpis náleží oné době, kdy "Nektere prikazy se provadeji nesmyslne dlouho(ls). Jine prikazy nezobrazi zadny vystup (top) a server nejde restartovat zadnym prikazem (shutdown -r now, reboot, init 6)". Pokud ne, pak to zkuste znovu ve chvíli, kdy k těmto problémům dochází.

[Lemmy]

Tak musim mirne upravit zneni problemu. Server na konec nezamrzne. Predchozi zamrznuti pricitam mym snaham o restart systemu.

Server zustave ve stavu kdy:

"Nektere prikazy se provadeji nesmyslne dlouho(ls). Jine prikazy nezobrazi zadny vystup (top) a server nejde restartovat zadnym prikazem (shutdown -r now, reboot, init 6)"

Na jednom ze serveru se my povedlo spustit program memtester a ten nezjistil zadne chyby.

Diky za vase reakce.

[Shadow]

OK, takže doporučuji následující. Až se některý ze serverů opět dostane do tohoto stavu, použijte strace na problémové příkazy:

strace top

strace ls

Pak se snad dozvíte, při provádění čeho to na něco čeká nebo proč to nezobrazí žádný výstup. Strace sice není úplně jednoduché interpretovat, ale snad vám poskytne alespoň nějaké vodítko.

Dal se nedostanu.

Diky za reakce.

Dle tohoto výpisu a tohoto příspěvku soudím, že by to mohl být problém s ACPI. Ale to nevysvětluje problémy s ls nebo top. Ještě byste mohl zkusit zkompilovat si vlastní jádro a pečlivě jej přizpůsobit vašemu HW. Mohl byste zkusit vanilla jádro, třeba i nějaké novější.

Možná by ale stálo za to nejprve projet vaší základní desku Googlem, jestli s ní někdo neměl nějaký podobný problém související s Linuxem.

Podivna vec se stala.

Pote co jsem na jednom serveru spustil parkrat strace s parametrem top a reboot, tak se server zacal chovat normalne. Top zacal fungovat a server sem normalne restartoval.

Na problem s ACPI jsem uz taky myslel, tak jsem ted nabootoval do starsiho jadra s parametry acpi=off noapic. Na vic, nenechavam zavadet modul asus_acpi.

[root@server log]# uname -a
Linux server 2.6.18-8.el5 #1 SMP Thu Mar 15 19:57:35 EDT 2007 i686 i686 i386 GNU/Linux

Na problem s ACPI by mozna mohlo naznacovat i fakt, ze kdyz sem servery instaloval a testoval, tak pri bootovani se neustale vypinal a zapinal monitor, takze nebylo mozne vlastni proces bootovani sledovat.

Uvidime jestli stabilni stav vydrzi. Po restartu se vzdy servery tvarili ok, ale po par hodinach nastal vyse zmineny problem.

Diky za reakci

Tak problem byl v power managementu.

Po pridani parametru acpi=off a noapic na radek kernel v menu.lst a vypnuti vsech daemonu nejak spojenyhc s rizenim spotreby server jede v poradku uz treti den.

Diky vsem za reakce.
