Hallo,

Gisteren dook er in de logwatch van m'n webserver een aantal smart foutmeldingen op. Maar dan manueel nog eens gaan uitlegen toonde niets speciaals. Op die moment was de IO wel verschrikkelijk traag. Precies een paar seconden vlot werken en dan weer hangen.
Ik heb alle virtuele machines afgesloten en gisterenavond gaan kijken in het datacenter. Updates gedaan en gereboot en hij leek weer normaal te draaien.

Systeem
SuperMicro PDSMI+
2 x 320GB WD Caviar SE16 in RAID1 on onboard Adaptec RAID controller
Scientific Linux 6.0

In de logwatch van afgelopen nacht staat het volgende:

En sinds vandaag staat er ook nog bij

---------------------- Kernel End -------------------------
Wat moet ik daar nu uit afleiden? Disk(s)? Moederbord? OS?
Google bracht mij op een oud forum waar men die errors aan de kernel verweet, dus een software probleem.
Ik heb 18 uren straight gewerkt en nu een paar uurtjes geslapen dus kan niet echt helder denken momenteel. All help would be appreciated
