Linux操作系统怎么解决“/boot”分区满了
生产服务器:
OS:CentOS 6.8
任务:yum upgrade #升级软件包,但不更改软件和系统配置,不升级内核。
问题:
运行 rpm_check_debug
执行事务测试
事务测试出错:
installing package kernel-2.6.32-642.11.1.el6.x86_64 needs 15MB on the /boot filesystem
出错情况
-------------
磁盘要求:
At least 15MB more space needed on the /boot filesystem.
[root@sky9896 /]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 49G 22G 25G 48% /
tmpfs 939M 44K 939M 1% /dev/shm
/dev/sda1 93M 75M 14M 85% /boot
/dev/sda5 179G 1.8G 168G 2% /home
解决方法:删除旧版的kernel
[root@sky9896 /]# rpm -qa|grep kernel
