我司入了台洋辣鸡做 NAS ,装上 Ubuntu 16.04 跑 ZFS 。
今天正好想起来,登上服务器把玩一番,一不小心就发现了奇怪的情况。
Ubuntu 趁人不备,在后台给我静默安装了 15 个不同版本的内核。
默默 dpkg 列出了所有的内核和脑袋,去掉当前的和最新的,剩下的统统拿去 purge 了。
Purge 花了不少时间,毕竟要处理各种 dkms 和 grub 呢。
全跑完一看……
ZFS 内核模块编译不通过……
仔细读了 Log 发现, 4.4.0-21 是能编译过的, 4.4.0-62 是一定会炸的。
回去跑了 dkms install zfs -v 0.6.5.6 -k 4.4.0-62-generic
看了眼,发现编译错误指向了一个系统 API :

默默翻出之前卸掉的那些脑袋包看了眼……

没什么好说的,滚回之前的版本就好了……
头一次信 Ubuntu ,就给我看这个……
