Then check the extended attributes on all bricks (inclusing the arbiter):
getfattr -d -e hex -m. /gluster/brick/path/to/filr/or/dir
Also, check glustershd.log on 192.168.1.51 & 192.168.1.40 for clues.

I am using GlusterFS version 9.3 on two Intel NUCs and a Raspberry PI as arbiter for a replicate volume. The whole thing serves me as distributed storage for a Proxmox cluster.I use version 9.3, because I could not find a more recent ARM package for the RPI (= Debian 11).
The partions for the volume:
NUC1
nvme0n1 259:0 0 465.8G 0 disk
└─vg_glusterfs-lv_glusterfs 253:18 0 465.8G 0 lvm /data/glusterfs
NUC2
nvme0n1 259:0 0 465.8G 0 disk
└─vg_glusterfs-lv_glusterfs 253:14 0 465.8G 0 lvm /data/glusterfs
RPI
sda 8:0 1 29,8G 0 disk
└─sda1 8:1 1 29,8G 0 part /data/glusterfs
The volume was created with:
mkfs.xfs -f -i size=512 -n size=8192 -d su=128K,sw=10 -L GlusterFS /dev/vg_glusterfs/lv_glusterfs
gluster volume create glusterfs-1-volume transport tcp replica 3 arbiter 1 192.168.1.50:/data/glusterfs 192.168.1.51:/data/glusterfs 192.168.1.40:/data/glusterfs force
After a certain time it always comes to the state that there are not healable files in the GFS (in the example below: <gfid:26c5396c-86ff-408d-9cda-106acd2b0768>).
Currently I have the GlusterFS volume in test mode and only 1-2 VMs running on it. So far there are no negative effects. The replication and the selfheal basically work, only now and then something remains that cannot be healed.
Does anyone have an idea how to prevent or heal this? I have already completely rebuilt the volume incl. partitions and glusterd to exclude old loads.
If you need more information, please contact me.
Thanks a lot!
