Zdar vsem,
cas od casu mi podivne spadne/vytuhne nejaky proces, vetsinou pri mirne
intenzivnejsich diskovych operacich probihajicich v noci v cronu (napr.
find / nebo rsync). Je tam ext3fs /dev/md0 150 GB (37% free), SW RAID 1
nad SATA disky, VIA chipset K8T800. Jeste je tam jeden zapomenuty PATA
disk 120 GB disk mountnuty na /data, 0% free...
AMD Athlon(tm) 64 Processor 3000+
RAID bus controller: VIA Technologies, Inc. VIA VT6420 SATA RAID
Controller (rev 80)
IDE interface: VIA Technologies, Inc. VT82C586A/B/VT82C686/A/B/VT823x/A/C PIPC Bus Master IDE (rev 06)
1 GB RAM, 1+1 GB swap na samostatne partitions (mimo RAID) a vetsinou nevyuzity.
Slusny zdroj (550 W tusim), slusny, pekne odvetrany case.
Teplota chipsetu 23 st.C, CPU 33 st.C, disku 30 st.C. a S.M.A.R.T. je klidny.
Kernel si pri tom stezuje takto:

Jsem z toho velmi neklidny. Uz jsem zkousel kernely 2.6.8, .12, .14 a
ted mam .15 (vsechno debianni pro k8) a problem pretrvava, takze to bude
spis nejaky HW problem, si myslim.
Nema nekdo tuseni, odkud vane vitr? A jak ho presmerovat jinam (treba
do /dev/null)?
Diky.
