ceph-mon 無法在 rasberry pi (raspbian 8.0) 上啟動
ceph-mon 無法在 rasberry pi (raspbian 8.0) 上啟動
我最近購買了 3 個樹莓派節點來創建一個小型儲存集群，以便在家中進行測試。我發現了一些設置程序，所以看起來人們已經成功地做到了！
我正在執行 Raspbian GNU/Linux 8.0 (jessie)。我正在使用 ceph-deploy 安裝集群，它似乎安裝了 ceph ARM 軟體包的 10.2.5-7.2+rpi1 版本。
當我嘗試啟動 ceph-mon 服務時，我從 systemd 收到以下錯誤：

root@ceph-master:~# cat /etc/apt/sources.list deb http://mirrordirector.raspbian.org/raspbian/ testing main contrib non-free rpi root@ceph-master:~# cat /etc/apt/sources.list.d/ceph.list deb https://download.ceph.com/debian-jewel/ jessie main有沒有其他人嘗試過這個並且遇到過類似的問題？有關如何繼續或解決此問題的任何建議？
我終於讓 ceph 在我的 Raspberry Pi 3s 上工作。Ceph 儲存庫只有用於 arm64 架構的 ARM 包。所有 armhf 包都不見了。我認為 ceph 社區不再關心 32 位，而一直專注於 64 位。訣竅是安裝 Ubuntu 的 arm64 版本。download.ceph.com 上唯一可用的 arm64 軟體包用於 xenial 或 trusty。在多次嘗試安裝 64 位版本的 ubuntu 失敗後，我使用了 64 位版本的 debian，只是將儲存庫更改為指向：
deb http://ports.ubuntu.com/ubuntu-ports xenial main universe deb http://ports.ubuntu.com/ubuntu-ports xenial-updates main universe deb http://ports.ubuntu.com/ubuntu-ports xenial-security main universe我在這裡找到了 64 位 rpi debian 映像：
https://github.com/bamarni/pi64/releases我已經啟動並執行了 ceph luminous！

正如@SYN 所說 - 使用更新版本的 ceph 可能會更幸運，其中可能會修復此錯誤。如果沒有，那麼您應該將錯誤以及上游日誌中可見的堆棧跟踪報告給 ceph 開發人員 - 當錯誤被擷取並修復時，每個人都應該很高興，尤其是在儲存軟體中。
