hello, Can somebody help me about attr : in doc i can read : The extended attributes can be seen in the backend filesystem using the getfattr command. (getfattr -n trusted.afr.version <file>) If i do that : getfattr -n trusted.afr.version /mnt/disks/export/images/C /mnt/disks/export/images/C: trusted.afr.version: No such attribute and if i do : attr -L -l /mnt/disks/export/images/import_1237221218 Attribute "glusterfs.afr.metadata-pending" has a 8 byte value for /mnt/disks/export/images/import_1237221218 Attribute "glusterfs.afr.data-pending" has a 8 byte value for /mnt/disks/export/images/import_1237221218 getfattr -n glusterfs.afr.metadata-pending /mnt/disks/export/images/mport_1237221218 /mnt/disks/export/images/import_1237221218: glusterfs.afr.metadata-pending: Operation not supported My backend filesystem is : XFS is it normal ?
