Mozda je Vedran mislio na acpi
http://www.lesswatts.org/projects/acpi/
predji (kad upalis masinku :)) sa ctrl+F1 u terminal 1
pa se loguj i onda kucaj:
vi /boot/grub/menu.lst
kad prolistas sve vidi jel ima idje ACPI=on.
Prebaci ih ( edit) na off

Onda bi npr tvoj celer gutao vise energije i manje se brinuo za okolis (nekoliko procesa manje).
Sta ti je sa hd-om? Jel’ i on 5 godina ribo file-ove?
radi li?
jel ti dma on ili off?
sudo hdparm /dev/tvojhd
/dev/sda7:
IO_support = 0 (default 16-bit)
readonly = 0 (off)
readahead = 256 (on)
geometry = 4865/255/63, sectors = 11100852, start = 65786238
ovaj slice ima fajde od hdparm (readahead=on)
ponekad se hd-ovi znaju pokvariti zbog ovih hdparm alatki.
Neki parametri su cak i opasni.
!
Options:
-a get/set fs readahead
-A get/set the drive look-ahead flag (0/1)
-b get/set bus state (0 == off, 1 == on, 2 == tristate)
-B set Advanced Power Management setting (1-255)
-c get/set IDE 32-bit IO setting
-C check drive power mode status
-d get/set using_dma flag
-D enable/disable drive defect management
-E set cd-rom drive speed
-f flush buffer cache for device on exit
-g display drive geometry
-h display terse usage information
-H read temperature from drive (Hitachi only)
-i display drive identification
-I detailed/current information directly from drive
-k get/set keep_settings_over_reset flag (0/1)
-K set drive keep_features_over_reset flag (0/1)
-L set drive doorlock (0/1) (removable harddisks only)
-M get/set acoustic management (0-254, 128: quiet, 254: fast)
-m get/set multiple sector count
-n get/set ignore-write-errors flag (0/1)
-p set PIO mode on IDE interface chipset (0,1,2,3,4,…)
-P set drive prefetch count
-q change next setting quietly
-Q get/set DMA tagged-queuing depth (if supported)
-r get/set device readonly flag (DANGEROUS to set)
-R register an IDE interface (DANGEROUS)
-s set power-up in standby flag (0/1) (DANGEROUS)
-S set standby (spindown) timeout
-t perform device read timings
-T perform cache read timings
-u get/set unmaskirq flag (0/1)
-U un-register an IDE interface (DANGEROUS)
-v defaults; same as -acdgkmur for IDE drives
-V display program version and exit immediately
-w perform device reset (DANGEROUS)
-W get/set drive write-caching flag (0/1)
-x tristate device for hotswap (0/1) (DANGEROUS)
-X set IDE xfer mode (DANGEROUS)
-y put drive in standby mode
-Y put drive to sleep
-Z disable Seagate auto-powersaving mode
-z re-read partition table
–direct use O_DIRECT to bypass page cache for timings
–Istdin read identify data from stdin as ASCII hex
–Istdout write identify data to stdout as ASCII hex
–verbose display extra diagnostics from some commands
–security-help display help for ATA security commands
–drq-hsm-error crash system with a “stuck DRQ” error (VERY DANGEROUS)
Nesto za filesystem format-e:
Ako su ti racunala puna media file-ova ( gledo sam ti reference
a ti ova racunala administriras, uzmi xfs za file sistem.
Dok nebude zfs gotov, xfs je za brzi pristup file-ovima bog i butina.
Uzdravlje
