我正在尝试让 urbackup 2.4.9.0 在 Ubuntu 19.10 x86 上运行。我有一个 2T usb 驱动器，已分区为 btrfs，但 urbackup_snapshot_helper 无法将其识别为 btrfs。
/etc/urbackup/backupfolder contains:
/media/BACKUP/urbackup
建议的测试程序https://www.urbackup.org/administration_manual.html#x1-10600011.6.3说 /media/BACKUP/urbackup/testA5... 不是 btrfs。我不知道 ...TestA5... 来自哪里。
% urbackup_snapshot_helper test
Testing for btrfs...
ERROR: not a btrfs filesystem: /media/BACKUP/urbackup/testA54hj5luZtlorr494
TEST FAILED: Creating test btrfs subvolume failed

知道我做错了什么吗？
我尝试附加运行“strace -f urbackup_snapshot_helper test”的日志，但我看不到附加文件的方法，并且粘贴内容对于该缓冲区来说太大。
有什么建议吗？
“urbackup_snapshot_helper test”的输出为： 测试 btrfs... 错误：不是 btrfs 文件系统：/media/BACKUP/urbackup/testA54hj5luZtlorr494 测试失败：创建测试 btrfs 子卷失败 测试 zfs... 测试失败：未通过 /etc/urbackup/dataset 设置数据集
我不知道为什么它说 /media/BACKUP/urbackup/testA54hj5luZtlorr494 不是 btrfs 文件系统。
/media/BACKUP/urbackup 是 btrfs。
