HyperLedger锯齿验证器 - 设备上没有空间

Question

我在Windows计算机上安装了Linux子系统，然后在Microsoft指南之后添加了Ubuntu应用程序，然后在Ubuntu的指南之后安装了HyperLeDger Sawtooth。一旦我通过运行验证器来测试它，我就会出现磁盘类型错误 -

$ sudo -u sawtooth sawtooth-validator -vv
[INFO cli] sawtooth-validator (Hyperledger Sawtooth) version 1.0.1
[INFO path] Skipping path loading from non-existent config file: /etc/sawtooth/path.toml

  File "/.../sawtooth_validator/server/cli.py", line 365, in main
    metrics_registry=wrapped_registry)
  File "/.../sawtooth_validator/server/core.py", line 114, in __init__
    global_state_db = LMDBNoLockDatabase(global_state_db_filename, 'c')
  File "/.../sawtooth_validator/database/lmdb_nolock_database.py", line 57, in __init__
    lock=True)
lmdb.DiskError: /var/lib/sawtooth/merkle-00.lmdb: No space left on device

错误似乎与他们的来源中的这一行相关，但是我不明白为什么我看到磁盘的警告，因为我有将近30GB的空间。

$ df -h
Filesystem      Size  Used Avail Use% Mounted on
rootfs          238G  211G   27G  89% /
none            238G  211G   27G  89% /dev
none            238G  211G   27G  89% /run

none            238G  211G   27G  89% /run/user
C:              238G  211G   27G  89% /mnt/c

启动此程序实际上会占用那么多空间，我在Linux子系统上做错了什么，我是否需要为验证器设置某种配置，还是该程序有问题？对此的任何见解都将非常有帮助。

锯齿区块链存储在一个稀疏的文件中，该文件似乎占据了许多千兆字节，但实际上具有空为零的零字节的"孔"。这可能会导致Windows的Ubuntu子系统问题，因为它试图映射 1024 x 1024 x 1024 x 1024 x 1024 x 1024 的内存，即 1 099 511 627 776 b 1024 gib 。
