有2个容器:
第一个容器(400Mb)在两种备份模式(SUSPEND和SNAPSHOT)下都能正常工作。 但第二个容器(25Gb)仅在SUSPEND模式下进行备份。 SNAPSHOT模式始终失败。
两个容器都在同一个文件夹(/ backups)中进行备份。
这是pve storage config /etc/pve/storage.cfg
:
dir: local
path /var/lib/vz
content images,iso,vztmpl,rootdir
maxfiles 0
dir: backups
path /backups
shared
content backup
maxfiles 3
/etc/pve/vzdump.cron
config:
PATH="/usr/sbin:/usr/bin:/sbin:/bin"
0 4 * * 3,7 root vzdump 100 --quiet 1 --mode snapshot --node proxmox --compress lzo --storage backups
15 4 * * 3,7 root vzdump 101 --quiet 1 --mode snapshot --node proxmox --compress lzo --storage backups
这是我的存储配置:

自由空间已足够。 / dev / pve1 / backup具有230Gb的可用空间,并且/ dev / pve1 / data可以使用360Gb。 可能原因是SWAP分区的小尺寸(仅7Gb)?如果是这样 - 我该如何扩展呢?
谢谢!

好吧,解决方案隐藏在vzdump工具的size
参数中(它为快照定义了已分配内存的值)。默认设置为500 Mb(proxmox v3.0)。将它改为4096解决了我的问题。
可以通过在/etc/vzdump.conf中添加以下行来配置它
size: 4096
或直接在cron /etc/pve/vzdump.cron
中添加--size 4096
键/值对。感谢。
