如果对应的目录存储空间不够,就会出现此类报错
解决方法:
扩大对应的存储空间或者在对应的目录里删除无用的数据

在本地局域网络中,各个设备的网卡都有自己的 ARP 缓存表,用于记录局域网中各个设备 IP 地址和 MAC 地址的对应关系。
# arp -d 192.168.0.1
(补充:这里以从本地 ARP 缓存表清楚 IP 地址 192.168.0.1 的 ARP 缓存为例)
# ping 192.168.0.1
(
补充:
1) 这里以获取 192.168.0.1 的 ARP 缓存为例。
2) 当本地尝试连接 IP 地址 192.168.0.1 时,首先发生 ARP 报文询问 IP 地址 192.168.0.1 的 MAC 地址获得 ARP 缓存。如果此缓存长期没有被使用则会自动删除。如果记录 ARP 缓存过多,那旧的 ARP 缓存会被有限删除

There may be some network storage disconnected
# mount
(Add: At this moment, we can see at least one remote storage mount to local directory. If we cd to this directory, system command prompt will output target is busy)
# umount -f <nfs storage which is stuck>
Or:
# umount -l <nfs storage which is stuck>
