You have been subscribed to a public bug:

Ubuntu 17.10 appears to aggressively trigger Samba bug 10541 (
https://bugzilla.samba.org/show_bug.cgi?id=10541 ). Previous versions of
Ubuntu worked fine, but 17.10 appears to request quota information on
every write, resulting in a complete inability to write to files.

Remote Samba share is mounted as cifs as read-write, and has been
working for years and many software releases. Unable to write/create
files from bash, from GUI file browser, or even from a Windows VM with
access to the mounted location. I haven't seen any scenario where Ubuntu
17.10 can write to the share.

Server is running Samba 4.7.3 with a long-running good configuration.

Every write request from my Ubuntu desktop results in the following
server log:

[2017/12/02 16:44:25.306674,  0] ../source3/lib/sysquotas.c:461(sys_get_quota)
  sys_path_to_bdev() failed for path [.]!

There are no other log entries.

The root bug appears to be in Samba, but recent changes to Ubuntu have
triggered the bug in a way that breaks write functionality.
