Hi Guys,

I am testing glusterfs and have configured replicated volume (replica=2 on two virtual machines), after play with the volume a while, there are un-consistent data reported by 'heal volname info':

u1@u1-virtual-machine:~$ sudo gluster volume heal mysqldata info

Gathering Heal info on volume mysqldata has been successful

Brick 192.168.53.218:/data/gv0/brick1/mysqldata

Number of entries: 1

<gfid:0ff1a4e1-b14c-41d6-826b-e749a4e6ec7f>

Brick 192.168.53.221:/data/gv0/brick1/mysqldata

Number of entries: 1

/ibdata1

1) What does this means?  Why one entry is file itself on one host, while another entry is gfid on another host? 

2) After a while (maybe 2 minutes), re-run heal info, and get following output. What happened behind the scene? Why the entry changes to file from gfid?

u1@u1-virtual-machine:~$ sudo gluster volume heal mysqldata info

Gathering Heal info on volume mysqldata has been successful

Brick 192.168.53.218:/data/gv0/brick1/mysqldata

Number of entries: 1

/ibdata1

Brick 192.168.53.221:/data/gv0/brick1/mysqldata

Number of entries: 1

/ibdata1

u1@u1-virtual-machine:~$ sudo gluster volume heal mysqldata info split-brain

Gathering Heal info on volume mysqldata has been successful

Brick 192.168.53.218:/data/gv0/brick1/mysqldata

Number of entries: 0

Brick 192.168.53.221:/data/gv0/brick1/mysqldata

Number of entries: 0

3) I tried with both heal and heal full, while heal seems not work, I still get above output.  How could I heal this case manually? Following is getfattr output.

u1@u1-virtual-machine:~$ sudo getfattr -e hex -m . -d /data/gv0/brick1/mysqldata/ibdata1

getfattr: Removing leading '/' from absolute path names

# file: data/gv0/brick1/mysqldata/ibdata1

trusted.afr.mysqldata-client-0=0x000000010000000000000000

trusted.afr.mysqldata-client-1=0x000000010000000000000000

trusted.gfid=0x0ff1a4e1b14c41d6826be749a4e6ec7f

Any comments are welcome, and thanks very much in advance!

Regards,

Yandong
