Hello

I'm having an issue with unison sync between local ext4 and jmtpfs fuse mount - mounting as follows:

/usr/bin/jmtpfs  -d -s -o allow_other ~/obsidian_unison
$ /usr/bin/unison -version
unison version 2.53.3 (ocaml 5.0.0)
$ /usr/bin/unison -ignorearchives '/home/michael/Documents/Obsidian/' '/home/michael/obsidian_unison/SanDisk SD card/Obsidian/'

At the same time, jmtpfs is giving me the following:

unique: 11914, opcode: RENAME (12), nodeid: 318, insize: 144, pid: 23504
rename /SanDisk SD card/Obsidian/Default Obsidian Vault/Blender/.unison.Referencing System.md.fe3ef188cfa11ac9d54260d66b45d36a.unison.tmp /SanDisk SD card/Obsidian/Default Obsidian Vault/Blender/Referencing System.md
   unique: 11914, error: -5 (Input/output error), outsize: 16

Renaming the file manually works as expected so I'm wondering what unison does differently. That leads to the assumption that unison wants to overwrite (by renaming .tmp) an existing file which it can't. Any ideas?

First, a serious question: Did you come across an exhortation to read https://github.com/bcpierce00/unison/wiki/Reporting-Bugs-and-Feature-Requests before creating an issue?

Please use the mailing list for questions. This issue does not articulate that there is a bug in unison and is really a question/request for help.
