docker 磁盘问题：device or resource busy
問題：[root@hdp-gp-dk02 ~]# docker start 01ea65845e45
Error response from daemon: Cannot start container 01ea65845e45: Error getting container 01ea65845e4547be24bc3db0bc3b424faf52b8a0534eb525aa829dd9fd6081c2 from driver devicemapper: Error mounting '/dev/mapper/docker-8:4-100794844-01ea65845e4547be24bc3db0bc3b424faf52b8a0534eb525aa829dd9fd6081c2' on '/var/lib/docker/devicemapper/mnt/01ea65845e4547be24bc3db0bc3b424faf52b8a0534eb525aa829dd9fd6081c2': device or resource busy

上面的問題告訴我們docker容器掛載的磁盤忙
相同的問題經(jīng)驗(yàn)解決：
umount /dev/cdrom /mnt ，也出現(xiàn)過?device or resource busy
解決方案就是卸載掛載目錄：umount /dev/cdrom 或者 umount /mnt
同理，只需要將容器的掛載目錄卸掉就行，我這么做了，也成功了。我想應(yīng)該就是這個(gè)問題。
[root@hdp-gp-dk02 ~]# umount /var/lib/docker/devicemapper/mnt/01ea65845e4547be24bc3db0bc3b424faf52b8a0534eb525aa829dd9fd6081c2
[root@hdp-gp-dk02 ~]# docker start 01ea65845e45

重新啟動(dòng)之后的容器成功了。
