Redhat system Read-only problem caused by drop disk

After the data disk is broken, replace the hard drive, enter the system again, FSCK does not pass, the system is read-only,

# "/" is currently read-only state

# Mount-o remount, rw/#变成可写状态

# Vi/etc/fstab

#/DEV/SDB1/SCR1 #把后面的 1 2 to 0 0, if the file system does not need to scan at startup, set this field to 0, 1, 2, respectively, indicating the level of disk detection, 0 indicates that the boot does not detect the hard drive

Reboot the system and enter the normal state.

# Fdisk/dev/sdb [m n P 1 return car return W]

# MKFS.EXT4/DEV/SDB1

# mount-a

Modify the/SCR1 uuid in Fstab to/DEV/SDB1
