Title:
16.04 LTS NFS4 Client hangs when copying large files
Status in linux package in Ubuntu:
Incomplete
Status in linux source package in Xenial:
Confirmed
Bug description:
When doing simple copy-jobs with large files (f.ex. Partition Images > 4
GByte filesize)the file transfer allways stall after about 16 GByte has passed
to the Client.
No Problems using kernel-versions up to kernel 4.2 (Ubuntu 14.04 up to 15.10).
Verified with new installations of 16.04 LTS as well as upgraded (previous
working) 15.10 workstations to 16.04 LTS.
Autonegotiated NFS-values are still the same:
Working 15.10 version:
server:/informatik/ab on /informatik/ab type nfs4
(rw,relatime,vers=4.0,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=krb5,clientaddr=134.100.9.19,local_lock=none,addr=XXX.XXX.XXX.XXX)
Failing 16.04 LTS Version:
server:/informatik/ab on /informatik/ab type nfs4
(rw,relatime,vers=4.0,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=krb5,clientaddr=134.100.9.19,local_lock=none,addr=XXX.XXX.XXX.XXX)
