Hello,
I just wanted to ask if you had time to look into this bug I am encountering and if there is anything else I can do?
For now in order to get rid of these 3 unsynched files shall I do the same method that was suggested to me in this thread?
Sorry Mabi, I haven't had a chance to dig deeper into this. The
workaround of resetting xattrs should be fine though.
Thanks,
Ravi
Thanks,

Hi Ravi,
Please fine below the answers to your questions
1. I have never touched the cluster.quorum-type option. Currently it is set as following for this volume:
Option Value
cluster.quorum-type none
2) The .shareKey files are not supposed to be empty. They should be 512 bytes big and contain binary data (PGP Secret Sub-key). I am not in a position to say why it is in this specific case only 0 bytes and if it is the fault of the software (Nextcloud) or GlusterFS. I can just say here that I have another file server which is a simple NFS server with another Nextcloud installation and there I never saw any 0 bytes .shareKey files being created.
3) It seems to be quite random and I am not the person who uses the Nextcloud software so I can't say what it was doing at that specific time but I guess uploading files or moving files around. Basically I use GlusterFS to store the files/data of the Nextcloud web application where I have it mounted using a fuse mount (mount -t glusterfs).
Regarding the logs I have attached the mount log file from the client and below are the relevant log entries from the brick log file of all 3 nodes. Let me know if you need any other log files. Also if you know any "log file sanitizer tool" which can replace sensitive file names with random file names in log files that would like to use it as right now I have to do that manually.

Hi mabi,
Some questions:
-Did you by any chance change the cluster.quorum-type option from the
default values?
-Is filename.shareKey supposed to be any empty file? Looks like the file
was fallocated with the keep-size option but never written to. (On the 2
data bricks, stat output shows Size =0, but non zero Blocks and yet a
'regular empty file').
-Do you have some sort of a reproducer/ steps that you perform when the
issue occurs? Please also share the logs from all 3 nodes and the client(s).
Thanks,
Ravi

Dear all,
I have upgraded my replica 3 GlusterFS cluster (and clients) last Friday from 3.12.7 to 3.12.9 in order to fix this bug but unfortunately I notice that I still have exactly the same problem as initially posted in this thread.
It looks like this bug is not resolved as I just got right now 3 unsynched files on my arbiter node like I used to do before upgrading. This problem started since I upgraded to 3.12.7...
Could you provide the stat and 'getfattr -d -m . - hex
brick/path/to/file' outputs of one of these files and also the
corresponding parent directory from all 3 bricks?
Thanks,
Ravi
Thank you very much in advance for your advise.

Again thanks that worked and I have now no more unsynched files.
You mentioned that this bug has been fixed in 3.13, would it be
possible to backport it to 3.12? I am asking because 3.13 is not a
long-term release and as such I would not like to have to upgrade to
3.13.
I don't think there will be another 3.12 release.
Why not? It is LTS, right?
My bad. Just checked the schedule [1], and you are right. It is LTM.
