The storage array was connected to the host and mapped a LUN to the host. An ext2 file system created on the mapped LUN was successfully mounted, but when a file was being copied to the mounted target directory, the host broke down immediately.
Power off the host and power it on again. After the system is running properly, perform the following operations:
1. Create a file system.
The related command is mkfs.ext3 /dev/sdX where sdX indicates the drive letter identified by the operating system.
You can also create a file system by using the mkfs -t ext3 /dev/sdX command.
2. Mount the file system.The related command is mount /dev/sdX /mnt.
This was a Kylin ext2 file system issue. Any security factor added to an ext2 file system may lead to a host breakdown.
Kylin engineers recommend that ext3 file systems be used to replace ext2 file systems on Kylin Linux 3 operating systems due to the breakdown issue on ext2 file systems. If ext2 file systems are absolutely necessary, contact Kylin service engineers for assistance.
