查看同步情况
ls -lA /mnt | wc -l
ls -lA
创建卷时报错 volume create: gv0: failed: /data/gv0/brick1 or a prefix of it is already part of a volume
A：之前创建卷时，报错，
volume create: gv0: failed
因此，有信息遗留，需要清理。
# cd /data/gv0/brick1
# attr -lq .
glusterfs.volume-id
# setfattr -x trusted.glusterfs.volume-id .
或者批量：
# cd /data/gv0
# for i in `ls .`; do setfattr -x trusted.glusterfs.volume-id $i; done
