Dotaz: pomale diskove operacie

[rimskij]

Zdravim, mam server, na nom bezia debian. Ked dam kopirovat vacsie mnozstvo dat, tak to spociatku ide rychlo (5-10s) potom rychlost pada a skonci to na 0,5-1,5MB/s. Mam tam 6x1GB SATA disky zapojene do HW raid5.

hpacucli> ctrl all show config detail vypise, ze je vsetko ok, aj raid, aj kazdy z diskov ale: hdparm -tT /dev/cciss/c0d0p3

/dev/cciss/c0d0p3: Timing cached reads: 7692 MB in 2.00 seconds = 3853.53 MB/sec Timing buffered disk reads: 14 MB in 3.32 seconds = 4.21 MB/sec

uz tak dobre nevyzera. Skusal som kopirovat 100GB subor a kopirovalo mi ho tri dni.

prikladam cast vypisu hpacucli, ak by tam niekto nieco videl, ale mne sa zda by ok. => ctrl all show config detail
