我这里是这样的
[Journal]
#Storage=auto
前面加了 # 就會被忽略 只有備忘用途
參閱
https://www.freedesktop.org/software/sy ... .conf.html
Storage=

Controls where to store journal data. One of "volatile", "persistent", "auto" and "none". If "volatile", journal log data will be stored only in memory, i.e. below the /run/log/journal hierarchy (which is created if needed). If "persistent", data will be stored preferably on disk, i.e. below the /var/log/journal hierarchy (which is created if needed), with a fallback to /run/log/journal (which is created if needed), during early boot and if the disk is not writable. "auto" is similar to "persistent" but the directory /var/log/journal is not created if needed, so that its existence controls where log data goes. "none" turns off all storage, all log data received will be dropped. Forwarding to other targets, such as the console, the kernel log buffer, or a syslog socket will still work however. Defaults to "auto".

刚才把journalctl 的结果输出到了文本文件,有40多M,应该从中找哪些关键字?

sudo journalctl -b --no-pager # current boot 本次開機
sudo journalctl -b 0 --no-pager # last boot 上次開機
sudo journalctl -b -1 --no-pager # previous boot 上上次開機
sudo journalctl -b -1 --no-pager # previous boot 上上上次開機
....
应该从中找哪些关键字?
關鍵字 過濾
sudo journalctl -b 0 --no-pager | grep 關鍵字
然後使用得到的開機錯誤關鍵字串 上網搜尋

提醒
不用了 把 Storage= 設定 改回來
[Journal]
#Storage=auto
否則 你的分割區空間會被佔用 越來越大

我用journalctl >> \home\log.txt
为何会得到一个40M的文件,里面有近一个月的信息。
内容是这样的:
