Override reported free space

[HiFiPhile]

Hi,

Long time no see :), is everything ok ?

I've a small issue in my new configuration:

Server

• Debian Busseye
• SFTPGo 2.2.2-a792150-2022-02-06T14:12:25Z +metrics +azblob +gcs +s3 +bolt +mysql +pgsql +sqlite +portable

SFTPGo's working directory is set to /var/run where no file will be stored, multiple ZFS pools shared as external folders.

$ df -h
192.168.10.1:/P4510                    5.6T  2.3T  3.4T  41% /media/zfs/p4510

Client

• archlinux
• SSHFS version 3.7.2
  FUSE library version 3.10.5
  using FUSE kernel interface version 7.31
  fusermount3 version: 3.10.5
• KDE dolphin 21.12.3

$ df -h
[email protected]:  1.6G  1.3M  1.6G   1% /media/sftp

Issue

When I copy big files to server with Dolphin, it fails with error "Not enough free space".

I think it's because Dolphin check free space before copy, since free space shown from client is wrong (it shows free space of SFTPGo's working directory).

If I copy with cp then this check is bypassed.

So is there a simple way to override the reported free space ? For example with a Windows rclone client it report 1.0 PB which is overkill.

Hi,

I'm fine hope the same for you.

I'm not sure if there is a bug somewhere in SFTPGo, but the client must specify a path when it requests the available disk space and SFTPGo should check the space for the requested path.

Unfortunately it seems there are no logs for this request, can you please debug the issue and report back the results? The disk space request is handled here. Thanks!

I did some tests with df, I think SFTPGo handles free space correctly:
df -h . give me the free space of SFTPGo's working directory /var/run
df -h ./xxx give me free space of external folders.

I think it's a KDE Dolphin's limitation, it tests only the free space of root mount point, rather the destination folder.

uhmm ... still no answer ... they don't seem very responsive

[HiFiPhile]

Yes, there are many bugs unanswered...

Same issue exist on Windows using https://github.com/winfsp/sshfs-win.

This looks like a bug on their side. Both KDE and sshfs-win have a lot of sponsorship and so resources to fix their bugs. I'm not going to add an hack/workaround that I have to maintain forever, sorry.
