Merhabalar
Sunucumuzda 3 adet 1.5 TB disk bulunmakta
2 adet disk Raid 1
1 Adet Disk tek başına çalışmaktadır.
Öncelikle SSH üzerinden işletim sistemininin RAID yapısında mi yoksa tek başına çalışan disk üzerinde mi olduğunu nasıl öğrenebiliriz?
Kullanılmayan disk RAID yapısında ise nasıl mount edebiliriz , solo disk ise nasıl mount edebilirim.
FDISK çıktısı aşağıdaki gibidir.
İyi Çalışmalar Herkese.
