上一篇《btrfs 翻车记》记叙了我们服务器上的 btrfs 出事的情况，好像吓到一些用户了 QAQ。其实那次情况比较特殊啦。一般来说，就算元数据用满了，也不至于改内核代码才能救回来。不过元数据满的问题确实困扰了许多用户，正好这些天群里有不少人遇到了，本文就记录一下元数据满了之后如何处置。问题和处置问题的现象是部分文件操作报错「No space left on device」，但是 df 等工具明明报告还有空间。btrfs filesystem usage的输出是这样：我们可以看到，还有 373G 的空闲空间（Free）呢。但是呢，「Device unallocated」已经不足 1G 了。在充分大的文件系统上，btrfs 会以 1G 为单位来分配块组（block group，简称 bg）。所以现在这个情况，已经无法分配新的 bg 啦。然后我们再往下看，「Metadata」的部分，总共 4.5G，已经用了 4G。还剩下 512M，刚好是 Global reserve 的大小。也就是说，不算保留空间的话，元数据已经没有空间可用了，所以才会报错。那现在怎么办呢？如果文件系统上有不需要的很大的文件，并且没有快照，删除后空间可以立即释放的话，可以删除试试，看看能不能刚好空出来一个 bg。不然就试着跑一下 balance，像这样：这个命令是说，把使用率为 0% 的数据 bg 整理一下。从输出 ...继续阅读 (130)
