Mongodb 突然失敗並顯示消息“設備上沒有剩餘空間”

Mongodb 失敗並顯示消息“設備上沒有剩餘空間”。蒙哥日誌：

$ sudo tail -n 5 ./mongodb/mongod.log

但我有足夠的空間和 inode：

$ df

/dev/ploop35670p1 2113654704 1530326948 497220988  76% /

$ df -i

作業系統版本：

$rpm -qa | grep centos-release
centos-release-6-8.el6.centos.12.3.x86_64

蒙哥版本：

$ mongod --version

我怎樣才能找到問題的根源？

您的“伺服器”實際上是 OpenVZ 主機上的容器。磁碟空間不足的不是您的 VPS，而是主機本身。請與您的託管服務提供商聯繫以報告問題。並停止使用 OpenVZ VPS。
