FreeBSD isletim sisteminde eger IDE\/SATA RAID kartiniz varsa bu RAID’i kontrol etmek icin atacontrol komutunu kullanabilirsiniz. Ayrica ide diskleriniz hakkinda bilgi almak icinde bu komut kullanilir:<\/p>\n
Sistem uzerindeki disk bilgilerini almak icin:<\/p>\n
# atacontrol list
\nATA channel 0:
\nMaster: no device present
\nSlave: no device present
\nATA channel 1:
\nMaster: no device present
\nSlave: no device present
\nATA channel 2:
\nMaster: ad4 <MAXTOR STM3160215AS\/4.AAB> Serial ATA v1.0
\nSlave: no device present
\nATA channel 3:
\nMaster: ad6 <MAXTOR STM3160815AS\/4.AAB> Serial ATA v1.0
\nSlave: no device present
\nATA channel 4:
\nMaster: no device present
\nSlave: no device present
\nATA channel 5:
\nMaster: no device present
\nSlave: no device present
\nATA channel 6:
\nMaster: no device present
\nSlave: no device present
\nATA channel 7:
\nMaster: no device present
\nSlave: no device present<\/p>\n
Ustte goruldugu gibi ata2 ve ata3’e sirasiyla ad4 ve ad6 diskleri takilmis.<\/p>\n
Daha onceden olusturgunuz ar0 adli raid1 sistem hakkinda bilgi almak icin:<\/p>\n
# atacontrol status ar0
\nar0: ATA RAID1 subdisks: ad4 ad6 status: READY<\/p>\n
Mesela ikinci disk bozuldu (ad6). Raid hakkinda bilgi almak icin su komut verildiginde<\/p>\n
# atacontrol status ar0
\nar0: ATA RAID1 subdisks: ad4 status: DEGRADED<\/p>\n
RAID’in DEGRADED mode’ta calistigi gorulur ve RAID icinde sadece ad4 oldugu gorulur.<\/p>\n
Daha sonra bozuk diski degistirmek icin once su komut verilerek ad6 raid’ten cikartilir:<\/p>\n
# atacontrol detach ata3<\/p>\n
Ustteki komut verildikten sonra dmesg ciktisinda
\nsubdisk6: detached
\nad6: detached
\nmesajlari alinir. Disk degistirilir ve yeni disk RAID’e tanitilir.<\/p>\n
# atacontrol attach ata3
\nMaster: ad6 <MAXTOR 6L080J4\/A93.0500> ATA\/ATAPI rev 5
\nSlave: no device present<\/p>\n
Ustteki komuttan sonra dmesg cikitisinda su satir gorulur:
\nad6: 152627MB <MAXTOR STM3160815AS 4.AAB> at ata3-master SATA150<\/p>\n
Daha sonra ad6 diski ar0 array’ine eklenir:
\n# atacontrol addspare ar0 ad6 ve array asagidaki tekrar build edilir:<\/p>\n
# atacontrol rebuild ar0<\/p>\n
Bu asamadan sonra yeni diske ilk diskteki bilgiler yazilmaya baslar. Bu senkronizasyon isleminin hangi asamada oldugunu gormek icin<\/p>\n
# atacontrol status ar0
\nar0: ATA RAID1 status: REBUILDING 35% completed
\nsubdisks:
\n0 ad4 ONLINE
\n1 ad6 SPARE<\/p>\n
VERILECEK KOMUTLARIN OZETI:<\/p>\n
# atacontrol detach ata3
\n< Bozuk ad6 diski degistirilir>
\n# atacontrol attach ata3
\n# atacontrol addspare ar0 ad6
\n# atacontrol rebuild ar0
\n# atacontrol status ar0<\/p>\n
