file operation (mv) unsusccessful - possible dataloss

[Rolf Leggewie]

moving a 700MB avi file over davfs2 to a web harddisk fails for no discernible reason. What's worse is that the file is then removed, resulting in dataloss (well, not quite since the file is still there ~/.davfs2/cache but most people wouldn't know)

$ mv ~/Videos/BBC.Paris.* /mnt/telekom/Videos/ -iv
‘/home/leggewie/Videos/BBC.Paris.2of3.Blood.and.Chocolate.XviD.MP3.REMAX.avi’ -> ‘/mnt/telekom/Videos/BBC.Paris.2of3.Blood.and.Chocolate.XviD.MP3.REMAX.avi’

davfs2 is the one from trusty, version 1.4.7-3.

I found this in syslog

Apr 15 17:23:07 localhost mount.davfs: open files exceed max cache size by 29 MiBytes

I guess the file should then be left where it is instead of moved to the cache and "disappear".

Please try to use the latest version - 1.5.6-0.1 to verify. I don't see this anymore from my side.

[Woodrow Shen (woodrow-shen)]

Due to the bug didn't update for a while, I assume this is gone from my test. Set to invalid.
