Description Michal Hájek 2013-06-13 04:38:33 UTC

Description of problem:

We used git version from 12th June (ie. yesterday) on Fedora 18 with 3.9.5 kernel.

local filesystem on client = xfs
underlaying filesystem on both servers (replica 2x of 1 brick) xfs on lvm
input file on local system generated: 4633 B of random numbers repeated to
file size 4688596000 , name = rndcore . File rndcore on local disc copied
from client to glusterfs volume, mounted via nfs :
cp -av rndcore /gluster_m/gs-home-u/ycore
‘rndcore’ -> ‘/gluster_m/gs-home-u/ycore’
cp: writing ‘/gluster_m/gs-home-u/ycore’: Unknown error 527
cp: failed to extend ‘/gluster_m/gs-home-u/ycore’: Unknown error 527
when mounted natively via fuse, write fails with bad file handle error
Glusterfs vol. size = 2TB.

This bug is observed also with native gluster client. 

Version-Release number of selected component (if applicable):


How reproducible:
always. Just use cp to copy big files.

Steps to Reproduce:
1. cp /local/fs/bigfile /mounted/gluster/

Actual results:
cp -av rndcore /gluster_m/gs-home-u/ycore
‘rndcore’ -> ‘/gluster_m/gs-home-u/ycore’
cp: writing ‘/gluster_m/gs-home-u/ycore’: Unknown error 527
cp: failed to extend ‘/gluster_m/gs-home-u/ycore’: Unknown error 527

or 
bad file handle error
Expected results:
copy file correctly

gluster volume transport was rdma only.
While testing with primitive custom copy C programm,  syscall
write() did not work reliably with bigger butter e.g. 120kB, 1MB ... (sometimes work, sometimes fail) .  Copying of  4.2GB file with buffer size 4096B was slow, but mostly worked.

Comment 2 Kaleb KEITHLEY 2015-10-22 15:40:20 UTC

pre-release version is ambiguous and about to be removed as a choice.

If you believe this is still a bug, please change the status back to NEW and choose the appropriate, applicable version for it.
