[Gluster-users] Gluster not recognizing available space

[Pat Haley]

Hi,

We are using gluster to present 3 bricks as a single name space.
We appear to have a situation in which gluster thinks there
is no disk space when there is actually plenty. I have restarted
the glusterd deamons on all three bricks and I still get the
following message

/bin/cp: cannot create regular file 
`./Bottom_Gravity_Current_25/344.mat': No space left on device

This is a 6Mbyte file.  The total space available on
gluster is 3.6T

Filesystem            Size  Used Avail Use% Mounted on
mseas-data:/gdata      55T   51T  3.6T  94% /gdata

Also, no single brick is full:

Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/the_raid-lv_data
                        15T   14T  804G  95% /data

Filesystem            Size  Used Avail Use% Mounted on
/dev/sdb1              21T   18T  2.1T  90% /mseas-data-0-0

Filesystem            Size  Used Avail Use% Mounted on
/dev/sdb1              21T   20T  784G  97% /mseas-data-0-1

What should we do to fix this problem or look at to diagnose
this problem?

Thanks.
