Re: Gluster clients can't see directories that exist or are created within a mounted volume, but can enter them.

Do the users have permission to see/interact with the directories, in addition to the files?

Yes, full access to directories and files.

Also testing using the root user.

Hi,

Please provide the gluster volume info. Do you see any errors in the client mount log file (/var/log/glusterfs/var-lib-mountedgluster.log)?

We've got an issue with Gluster (3.12.x) where clients can't see directories that exist or are created within a mounted volume.

We can see files, but not directories (with ls, find etc...)

We can enter (cd) into directories, even if we can't see them.

- Host typology is: 2 replica, 1 arbiter.

- Volumes are: replicated and running on XFS on the hosts.

- Clients are: GlusterFS native fuse client (mount.glusterfs), the same version and op-version as the hosts.

- Gluster server and client version: 3.12.2 (also found on 3.12.1, unsure about previous versions) running on CentOS 7.

Examples:

mount:

192.168.0.151:/gluster_vol on /var/lib/mountedgluster type fuse.glusterfs (rw,relatime,user_id=0,group_id=0,default_permissions,allow_other,max_read=131072)

 

root@gluster-client:/var/lib/mountedgluster  # ls -la

total 0

 

(note no . or .. directories)

 

root@gluster-client:/var/lib/mountedgluster  # touch test

root@gluster-client:/var/lib/mountedgluster  # ls -la

total 0

-rw-r--r--. 1 root root 0 Nov  6 10:10 test

 

("test" file shows up. Still no . or .. directories.)

 

root@gluster-client:/var/lib/mountedgluster  # mkdir testdir

root@gluster-client:/var/lib/mountedgluster  # ls -la

total 0

-rw-r--r--. 1 root root 0 Nov  6 10:10 test

 

(directory was made, but doesn't show in ls)

 

root@gluster-client:/var/lib/mountedgluster  # cd testdir

root@gluster-client:/var/lib/mountedgluster/testdir  # ls -la

total 0

 

(cd works, no . or .. shown in ls though)

 

root@gluster-client:/var/lib/mountedgluster/testdir  # touch test

root@gluster-client:/var/lib/mountedgluster/testdir  # ls -la

total 0

-rw-r--r--. 1 root root 0 Nov  6 10:10 test

 

(can create test file in testdir)

 

 

root@gluster-client:/var/lib/mountedgluster/testdir  # cd ..

root@gluster-client:/var/lib/mountedgluster  # ls -ld testdir

drwxr-xr-x. 2 root root 4096 Nov  6 10:10 testdir

 

(going back to parent directory, although ls -la doesn't show the directory, if I specify the name to ls -ld it does show)
