Windows server 2012 R2 samba copied files 0kb in size

[sekurilabs]

Hi,

I'm using latest svfs to mount vanilla swift storage in linux. Mounted storage is then shared with a windows server via samba (cifs) and mounted as a disk in windows server.

Now I'm trying to copy files to the mounted samba (swift storage and all of them copy with file size 0 kb or empty).

I'm mounting swift with following command in ubuntu server: mount -t svfs -o username=swift_user,password=pswd,tenant=store,auth_url="http://1.2.3.4:5000/v2.0",mode=0777,allow_other,attr,xattr,go_gc=50 device /home/ubuntu/storage_folder

What am I doing wrong?

Update: Moving files from ubuntu server to mounted storage containers (folders) also results in files in size of 0. Copying works.

Update 2: Windows is reporting: "Request operation is not supported" on copying files or moving them via powershell. Copying files or moving them through explorer just hangs forever. I can create containers and empty files from explorer, but not copy files. I can access files already stored in the store.

Update 3 (debug output):

Update 4: Cloudfuse works and I can copy files, but it's seriously unstable and crashes all the time.

@xlucas Can you help me out on this? It's kinda urgent.

Update 5: OpenReadWrite is not supported and this is not a PUT request like OpenWriteOnly which is why operation fails. I have probably answered my question.

Thanks!

Hi @vsecure

did you manage to solve this issue? I'm also getting an error=ENOENT

Unfortunately not, openstack doesn't support mv command, only copy. To move the file you need to copy it first to new destination, and then remove the file in the original destination.
