Na virtualizacnimu serveru KVM stava, ze se v cyklu vypinaji a zapinaji jadra procesoru (po cca 10min) a vzdy se na cca 15s zasekne jak server tak virtualni stroje
pred tydnem po vikendove bource zacal hlasit chyby datovy disk, tak jsme jej vymenili ale systemovy zustal stejny, pouze ve snaze vyresit problem jsme upgradovali system z ubuntu natty (kernel 2.6) na ubuntu precise (3.2), problem zustava
Nasel jsem jen jednu diskuzi
http://ubuntuforums.org/showthread.php?p=12071553Zkousel jsem zapnout logovani a hledat ve stejnem case v logu jadra
/sys/kernel/debug/tracing/trace_pipe ale je to fofr a zadnou zvlastnost sem nevidel
Spojuji to s poruchou disku, ze se mohlo stat jeste neco jineho, ze by mohl system dostavat nejaky chybny signal z desky.. power suspend
Nestalo se vam neco podobneho? Nevite kam kouknout? Diky
