Description Jacob Shucart 2010-12-09 16:33:13 EST
I created a Gluster volume with 2 servers in replicate mode.  I mount the volume using NFS.  When I type df everything shows up normally:

[root@jacobgfs31-s1 test]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
                      3.8G  2.8G  819M  78% /
/dev/mapper/VolGroup00-LogVol02
                      1.5G   69M  1.3G   5% /data
/dev/vda1              99M   19M   75M  21% /boot
tmpfs                 250M     0  250M   0% /dev/shm
localhost:/dynamictest
                      2.9G  137M  2.6G   5% /test

I then add 2 new bricks and run df and it starts complaining:

[root@jacobgfs31-s1 ~]# gluster volume add-brick dynamictest jacobgfs31-s3:/data jacobgfs31-s4:/data
Add Brick successful
[root@jacobgfs31-s1 ~]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
                      3.8G  2.8G  819M  78% /
/dev/mapper/VolGroup00-LogVol02
                      1.5G   69M  1.3G   5% /data
/dev/vda1              99M   19M   75M  21% /boot
tmpfs                 250M     0  250M   0% /dev/shm
df: `/test': Invalid argument


I let it sit for a while and the error stayed around.  If I then cd to /test I'm able to write files, everything works, and when I hit df again, the error goes away.  This is a minor issue it appears, but someone(StreamTheWorld) did encounter it in their testing.

Jacob,
 We fixed a bug sounding very similar in 3.1.2qa1. Can you please verify if that fix works for this situation as well?

Thanks,
Avati

Does not happen in 3.2.3. Jacob can I close the bug?
