Linux系统卸载磁盘时报错that use the device is found by lsof(8) or fuser(1)查看挂载
今天在卸载磁盘时报错
[root@cosmo-lt-03 ~]# umount /data
umount: /data: target is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))
报错原因:
报错描述很明显,还有别的进程在对磁盘进行读写
解决办法:
fuser -m -v /dev/vdb
然后kill -9 进程ID
如果没有此命令,则安装
yum install -y psmisc
或者使用:
lsof |grep /data
然后同样kill -9 进程ID
如果没有此命令,则安装
yum install -y lsof
Linux查看挂载的三种方式
# 方法1
df -Th
# 方法2
mount -l
# 方法3
cat /etc/mtab
然后就可以接着进行卸载了
No pain, no gain!
