Linux下添加第二块scsi硬盘
1.关机接好第二块SCSI硬盘 2.开机进入linux系统,输入fdisk -l 或者dmesg |grep sdb（这个命令会显示本机第2块硬盘的信息） 3.fdisk /dev/sdb [root@OracleDB ~]# fdisk /dev/sdb The number of cylinders for this disk is set to 1044. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Command (m for help): m Command action a toggle a bootable flag b edit bsd disklabel c toggle the dos compatibility flag d delete a partition l list known partition types m print this menu n add a new partition o create a new empty DOS partition table p print the partition table q quit without saving changes s create a new empty Sun disklabel t change a partition''s system id u change display/entry units v verify the partition table w write table to disk and exit x extra functionality (experts only) Command (m for help): n Command action e extended p primary partition (1-4) 1 Invalid partition number for type `1'' Command action e extended p primary partition (1-4) p 然后fdisk -l 会看到/dev/sdb1这个分区 下面把这个分区格式化成ext3格式 然后格式化分区,创建文件系统 mkfs -t ext3 /dev/sdb5,等一会儿就完成了. 创建mount point: #cd / #mkdir app 测试是否MOUNT #mount -t ext3 /dev/sdb5 /app 一举成功. #umount /app /dev/sdb5 /app ext3 default 1 2 保存后运行命令 mount -a 结果ok, cd /app 发现了lost found.
