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
