When I try to copy a file to a sshfs-mounted directory, an error message appears in Dolphin 16.12.1 (64-bit Arch Linux): cannot save file . disk full The behavior is a bit different than in bug 357930 - it is possible to create new files. It is also possible to edit, append some data and save them (e.g. in Kate). But it is not possible to copy files. Dolphin always shows "Unknown size" in the lower right corner. The same bug exists in Krusader - but it shows "0 bytes left from 0 bytes (fuse.sshfs)" instead. This bug did not exist in the previous versions of Dolphin - the free space was displayed correctly and it was possible to copy files in version 16.08.
Seems to work for me, tried with ctrl+c and ctrl+v shortcuts. How were you copying the files?
Sorry for the confusion, I have now verified that the issue occurs only if I mount a Cygwin's /cygdrive directory through sshfs. Then, the Windows drives become the subfolders of this mounted cygdrive directory and their sizes/free space cannot be detected by Dolphin. But, if I mount e.g. /cygdrive/c directly, the free space is detected successfully. Also, in all cases, df . shows correct drive size and free space.
I have same problem with sshfs sometimes https://i.imgur.com/CpsPxqi.png Drive mounted with command sshfs root@192.168.1.41:/ /home/username/mnt/mobile -p 2222 -o reconnect,allow_other,gid=1000 It's a Android device with SshHelper app as ssh server. I can copy files into with cp command but Dolphin and Krusader fail.
I run KDE Neon 18.04 latest.
