Data Disappears after pull

Questions
1

I have several remotes and one of them stores dvc<3.0 data. I tried to pull some data from it:

(venv) ermolaev@df783b0a927d:~/projects/.../mae$ dvc pull -r mae-gdrive -R data/full_datasets/.../datasets/train.dvc

1 file modified and 1 file fetched

Data has downloaded but one of the files has disappeared:

I use symlink cache and file isn’t in cache. But it’s on a remote cache.

$ dvc doctor

Why my file didn’t downloaded? Why DVC didn’t throw any error? There are several files that din’t download correctly actually and I don’t known why

One more example:

1 file modified and 1 file fetched

While pulling was performing I looked into the cache:

ermolaev@df783b0a927d:~/$ du -hs /data/projects/radml/DVC_CACHE//b6/a687b7981fff05220507af4077f091

ermolaev@df783b0a927d:~/$ du -hs /data/projects/radml/DVC_CACHE//b6/a687b7981fff05220507af4077f091
du: cannot access '/data/projects/radml/DVC_CACHE//b6/a687b7981fff05220507af4077f091': No such file or directory

We can see, that after download I had file into cache, but after fetching it has disappeared.
