Hello, I just wanted to let you know that last week I have upgraded my two replica nodes from Debian 8 to Debian 9 so now all my 3 nodes (including aribter) are running Debian 9 with a Linux 4 kernel. Unfortunately I still have the exact same issue. Another detail I might have not mentioned yet is that I have quotas enabled on this volume, I don't really know if that is relevant but who knows... As a reminder here is what happens on the client side which has the volume mounted via FUSE (take earlier today from the /var/log/glusterfs/mnt-myvol-private.log logfile). Note here that in this specific case it's only one single file who had this issue.

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. > > > > > > > > > > NODE 1 brick log: > > > > > > > > > > [2018-05-15 06:54:20.176679] E [MSGID: 113015] [posix.c:1211:posix_opendir] 0-myvol-private-posix: opendir failed on /data/myvol-private/brick/cloud/data/admin/files_encryption/keys/files/dir/dir/anotherdir/dir/OC_DEFAULT_MODULE [No such file or directory] > > > > > > > > > > NODE 2 brick log: > > > > > > > > > > [2018-05-15 06:54:20.176415] E [MSGID: 113015] [posix.c:1211:posix_opendir] 0-myvol-private-posix: opendir failed on /data/myvol-private/brick/cloud/data/admin/files_encryption/keys/files/dir/dir/anotherdir/dir/OC_DEFAULT_MODULE [No such file or directory] > > > > > > > > > > NODE 3 (arbiter) brick log: > > > > > > > > > > [2018-05-15 06:54:19.898981] W [MSGID: 113103] [posix.c:285:posix_lookup] 0-myvol-private-posix: Found stale gfid handle /srv/glusterfs/myvol-private/brick/.glusterfs/f0/65/f065a5e7-ac06-445f-add0-83acf8ce4155, removing it.
