SUMMARY This tends to happen on sshfs mounted drives BUT ONLY happens when I'm using Dolphin. When I try to copy files to the sshfs drive I sometimes get an error that there isn't enough disk space even when there is plenty. I would note that the free space is listed as being plenty big in Dolphin. STEPS TO REPRODUCE 1. Copy files to sshfs 2. Receive error for no known reason OBSERVED RESULT Error copying, say, 128 megabytes of data onto a share that says it has 35 gigabytes free EXPECTED RESULT No error. SOFTWARE/OS VERSIONS Linux/KDE Plasma: 5.21.3 (available in About System) KDE Plasma Version: 5.21.3 KDE Frameworks Version: 5.84.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION I initially noticed that sshfs was reporting the free space of the directory in which the drives were mounted such that if the /media directory had 100 megabytes then even if the drives had 100 gigabytes, it would only report the 100 megabytes as free space and would behave like this. I worked around that by mounting them on a drive with much more free space but now that doesn't seem to do the trick.
Still an issue. Reports 2,3Gb total size with 500MB free on a sshfs mounted disk with more then 4TB disk space free.
I'm experiencing the same thing with a Backblaze bucket mounted using s3fs-fuse. `df` reports 16 exabytes(!) free, and copying files using shell commands work just fine.
