Hi Nithya,

Over the weekend there was a maintenance window and the version of
gluster was updated from 5.3 to 5.6, and the entire cluster was
rebooted, but the dht xattr is still missing:

[root at gluster07 ~]# getfattr --absolute-names -m . -d -e hex
/mnt/raid6-storage/storage/
# file: /mnt/raid6-storage/storage/
security.selinux=0x756e636f6e66696e65645f753a6f626a6563745f723a756e6c6162656c65645f743a733000
trusted.gfid=0x00000000000000000000000000000001
trusted.glusterfs.6f95525a-94d7-4174-bac4-e1a18fe010a2.xtime=0x5d35e1ab000a0ba6
trusted.glusterfs.quota.dirty=0x3000
trusted.glusterfs.quota.size.2=0x00001b6a366e74000000000000763ca3000000000005ce66
trusted.glusterfs.volume-id=0x6f95525a94d74174bac4e1a18fe010a2

[root at gluster07 ~]# rpm -q glusterfs
glusterfs-5.6-1.el7.x86_64

[root at gluster07 ~]# uname -r
3.10.0-957.21.3.el7.x86_64

Thanks,
 -Matthew
