我有一些音频文件被复制到 ZFS 文件系统，但是用 VLC 打开它们几分钟后，文件和 VLC 崩溃了，目录中没有任何音频文件。
当发生这种情况时，我意识到正在进行清理，并且后台还有另一个用户会话。故障发生后，从 GNOME 系统监视器检查，RAM 使用量显然已达到 RAM 限制（16GB 中为 10.xGB）。
该池是 RAIDZ2 池，仅存储数据。池称为“数据”，卷称为“木”。Ubuntu 18.04 位于单独的单个磁盘上。顺便说一句，我没有交换分区。
该机器可用作 NAS 和台式电脑。它有 4 个 2TB WD Red HDD，16GB ECC 无缓冲 RAM。
以下是输出apt list --installed *zfs*：
