Description Saurabh 2013-10-22 06:46:59 UTC

Description of problem:
Here I had single brick distribute volume.
enabled quota and set a limit after that tried to create random size files in it.
Now again increased the quota limit to twice of earlier one set.
This time copy the files earlier created in a directory.

And it says EIO.



Version-Release number of selected component (if applicable):
glusterfs3.4.0.35.rhs

How reproducible:
happened twice till now

Steps to Reproduce:
1. create a volume, start it
2. enable quota, set limit on the root of the volume to 1GB
3. mount it over nfs
4. create a directory inside the mountpoint
5. start creating random sized files, till quota limit is reached
6. increase the limit to 2GB
7. create a new directory, cp the data created earlier to newly created directory

Actual results:

[root@konsoul dir3]# cp * ../dir4/
cp: closing `../dir4/f.96': Input/output error
cp: closing `../dir4/f.97': Input/output error
cp: closing `../dir4/f.98': Input/output error
cp: closing `../dir4/f.99': Input/output error

Also, the same files that are showing EIO, are copied as truncated files.

example,
[root@konsoul dir3]# ls -l f.96
-rw-r--r--. 1 root root 12582912 Oct 22  2013 f.96
[root@konsoul dir3]# ls -l ../dir4/f.96
-rw-r--r--. 1 root root 7405568 Oct 22  2013 ../dir4/f.96
[root@konsoul dir3]# pwd
/mnt/nfs-dist1/dir1/dir1/dir2/dir3
[root@konsoul dir3]# 


Expected results:
if space is available then it should mention "Disk quota exceeded" not EIO

Additional info:

Client is RHEL 6.2

Comment 2 Saurabh 2013-10-22 06:59:53 UTC

updating the Expected results section,
Expected results:
if space is NOT available then it should mention "Disk quota exceeded" not EIO
