[Gluster-users] Brick missing trusted.glusterfs.dht xattr

[Matthew Benstead]

Hi Nithya,

No - it was added about a year and a half ago. I have tried re-mounting
the volume on the server, but it didn't add the attr:

[root at gluster07 ~]# umount /storage/
[root at gluster07 ~]# cat /etc/fstab | grep "/storage"
10.0.231.56:/storage /storage glusterfs
defaults,log-level=WARNING,backupvolfile-server=10.0.231.51 0 0
[root at gluster07 ~]# mount /storage/
[root at gluster07 ~]# df -h /storage/
Filesystem            Size  Used Avail Use% Mounted on
10.0.231.56:/storage  255T  194T   62T  77% /storage
[root at gluster07 ~]# getfattr --absolute-names -m . -d -e hex
/mnt/raid6-storage/storage/
# file: /mnt/raid6-storage/storage/
