Dotaz: tagovany bonding + netbackup = FIAL

[drunkezz]

ole amigos.

mam problem s netbackupom nad tagovanym interfacom(resp. bondingom)

situacia je taka ze robim bonding bond0 z eth0 a eth2, pre produkcny DB konekt v nativnej VLANe, a nad nim tagovany bond0.3016 pre backup traffic. no a tu sa to chova cudne, DB traffic je OK, ale backup traffic je zle. Netbackup sa konektne na klienta ..vymenia si par info a padne to. akonahle pustim ten backup nad netagovanym hocijakym interfacom z toho bondingu tak to pekne prebehne.

Mate niekto podobnu skusenost?

 

log z netbackupu

Ten popis je nějaký zmatený… Raději ukažte výstup

  ip addr show
  ip route show
  cat /proc/net/bond/bond0

a napište, jaké adresy používají klient a server.

Nad bond0 je este bond0.3016 cez ktoru tecie ten backup traffic ..a presne ten je problemovy

 

cat /etc/sysconfig/network-scripts/ifcfg-bond0.3016

A odkud kam je to spojení (funkční i nefunkční)?

[drunkezz]

funkcne aj nefunkcne spojenie je cez tie iste ipky aj cesty..jediny rozdiel je v tom ze raz je pouzity na klientovy tagovany interface a raz nie...

toto nic nema s routingom, nastavenim siete atd...je to len o tom ci sa s tym niekto nestretol

ale poviem to takto..asi to nema velky vyznam je to velmi specificka situacia, skusim este prehodit drajvre na sietovkach a uvidime.

Dakujem aj tak.

[Michal Kubeček]

Nějak dneska nemám náladu hrát si na výslech. Takže asi takhle: buď popište funkční a nefunkční konfiguraci včetně toho, mezi jakými adresami má být to spojení (a nejlépe i to, co z něj vlastně nefunguje, tj. který směr a kam až se pakety dostanou), nebo se obraťte na nějaké fórum, kde se scházejí jasnovidci.

toto nic nema s routingom, nastavenim siete atd

Z čeho jste to vyvodil?

skusim este prehodit drajvre na sietovkach

Co přesně myslíte výrazem "prehodit drajvre"?

[drunkezz]

absoultne uznavam, ze som to napisal ako tatar, ale podla mna sa jedna o tak specificku zalezitost, ze mnou uvedeny popis uplne na zaciatku by trkol len cloveka, ktory sa stretol s presnymi, alebo podobnymi symptomami.

Nebudem to dalej rozvijat.

Nebude s tímhle přístupem lepší jít vyvolávat dotaz na hlavní nádraží?

[Dan]

a nebude problem v mtu na tom bond0 1500 ale vlan ma mat o 4B viac 1504?

na bond1 je 9000 skuste ich zmenit cez ten interface

[drunkezz]

Ok takze sme to vyriesili, po milion kadejakych pokusov s MTU nastavenim kariet a siete zabralo az vypnutie offloadingov a checksumingov na kartach.
