OpenVZ 容器在重啟後不會啟動

這修復了其中一個：
ploop check -F /vz/private/183/root.hdd/root.hdd ploop mount /vz/private/183/root.hdd/DiskDescriptor.xml fdisk -l /dev/ploop32942 e2fsck /dev/ploop32942p1但是，其中一個之後我在啟動時得到了這個：

Container was stopped Unmounting file system at /vz/root/183 Unmounting device /dev/ploop32942 Container is unmounted之後，當我嘗試再次啟動容器時失敗，我必須再次 e2fsck 它但嘗試再次啟動它我遇到了同樣的問題。

事實可能是因為磁碟是 GPT 導致 fsck 無法正常工作嗎？
硬體重啟後，以下建議的解決方案有助於一一啟動失敗的容器：
# ploop check -F /vz/private/139/root.hdd/root.hdd # ploop mount /vz/private/139/root.hdd/DiskDescriptor.xml # fdisk -l /dev/ploop56824 # e2fsck /dev/ploop56824p1 # vzctl start 139 Dump file /vz/dump/Dump.131 exists, trying to restore from it Restoring container ...

Restoring completed successfully謝謝，幫了大忙！
