我的服务器的总内存与 USED + FREE 内存不匹配。我正在使用 linux 免费命令
My server's total memory doesn't match with USED + FREE memory. I'm using linux free command
我不太确定我的记忆发生了什么。我总共有31G内存，用的是1G，空闲的是9G。
我的问题是，为什么，我只有9G，1G = 10G。与总内存31G相去甚远
我希望四处看看1G used and ~29G free。谁能帮忙解释一下？
$ free -m
total used free shared buff/cache available
Mem: 31757 1264 9377 342 21114 29855
Swap: 2047 2 2044
$ free -g
total used free shared buff/cache available
Mem: 31 1 9 0 20 29
Swap: 1 0 1
buff/cache: 21114
您的操作系统将 "free" 内存用于 caching。

used by the operating system for the page cache. Since the memory
would otherwise be idle and is easily reclaimed when applications
request it, there is generally no associated performance penalty [...]
