NFSv4:在没有票证的情况下访问共享时,机器无响应

NFSv4:在没有票证的情况下访问共享时,机器无响应

我们正在实施 NFSv4_kerberos,以便在 RHEL 9 机器上挂载主目录。我们的想法是,如果用户有一个 cronjob,在票证过期后写入已挂载的主目录,整个机器就会变得非常无响应,以至于我甚至无法使用 GUI。

使用top,我看到了这个:

root      20   0  622392  74816  12876 R 100.0   0.9   1267:35 udisksd

有时是这样的:

1878523 ec-fran+  20   0  121020  40352   8276 R  48.2   0.5 991:14.60 systemd

有没有办法尽量减少这个问题?我们不知道用户会闲置多长时间,所以现在使用 NFSv4 风险太大,因为只要有一个闲置用户,整个虚拟机就会失去响应。

我发现我编写的每小时向主目录写入一些简单内容的脚本失败了,但为什么整个过程会导致机器无响应?

以下是journalctl -f日志:
