[Gluster-users] mkdir -p, cp -R fails

[Stefan Solbrig]

Dear all,

I have problem with glusterfs 3.12.4  

mkdir -p  fails with "no data available" when umask is 0022, but works when umask is 0002. 

Also recursive copy  (cp -R  or cp -r) fails with "no data available", independly of the umask.

See below for an example to reproduce the error.  I already tried to change transport from rdma to tcp. (Changing the transport works, but the error persists.)

I'd be grateful for some insight.

I have small test system that still runs on glusterfs 3.12.3, where everything works fine.

best wishes,
Stefan
