Description

I see a memory leak when importing raw devi?e.

Export Scheme:
[rbd@rbdbackup ~]$ rbd --no-progress -n client.rbdbackup -k /etc/ceph/big.keyring -c /etc/ceph/big.conf export rbdtest/vm-111-disk-1 - | nc 10.43.255.252 12345

[root@ct2 ~]# nc -l 12345 | rbd import --no-progress --image-format 2 - rbd/vm-111-disk-1

This is the same problem with ssh.
Memory usage, see the screenshots.

Hi, Sage.

I'm sorry, was wrong to put up parameter: rbd_cache size
The problem is not confirmed.

As a suggestion, prohibit the use of the cache when RDB imports.

I quickly attempted to reproduce this on the same version w/o success. Can you attach /etc/ceph/big.conf? How large is the image that you are importing?

Hi, Jason.

It was not a mistake in the code, I made ??a mistake with the parameter rbd_cache_size:
rbd_cache size = 134217728000 //130 GB :)
