根因分析

检查点目录所在的磁盘分区 inode 或块耗尽，导致 SaveV2 操作失败。

English

The disk partition where the checkpoint directory resides has run out of inodes or blocks, causing the SaveV2 operation to fail.

解决方案

  1. Check disk usage with 'df -h' and 'df -i', then delete unnecessary files or expand the partition. Alternatively, change checkpoint path to a partition with more space using tf.train.CheckpointManager with a different directory.
  2. Enable checkpoint compression by setting options.experimental_io_device='/job:localhost' and using tf.train.CheckpointOptions(experimental_io_device='/job:localhost', experimental_enable_async_checkpoint=True) to reduce immediate disk usage.

无效尝试

常见但无效的做法:

  1. Delete random files in /tmp to free space 60% 失败

    The checkpoint path may not be in /tmp; also deleting unrelated files can cause other failures.

  2. Set TF_CPP_MIN_LOG_LEVEL=2 to suppress the error 90% 失败

    Suppressing logs does not resolve the underlying disk space issue; the checkpoint will still not be saved.

  3. Reduce batch size to reduce checkpoint size 80% 失败

    Checkpoint size is determined by model parameters, not batch size; reducing batch size does not free disk space.
