[Gluster-users] SAMBA VFS module for GlusterFS crashes

Hello,

I'm trying to set up a SAMBA server serving a GlusterFS volume.
Everything works fine if I locally mount the GlusterFS volume (`mount
-t glusterfs ...`) and then serve the mounted FS through SAMBA, but
the performance is slower by a 2x/3x compared to a SAMBA server with a
local ext4 filesystem.

I gather that SAMBA vfs_glusterfs module can give better
performance. However, as soon as I switch SMBD to using GFAPI (`vfs
objects = glusterfs`), the SMBD process crashes leaving a backtrace in
the logs.  I can see no errors in the associated GlusterFS log file
and everything runs fine when locally-mounting.  I am copying below
the share definition, SMBD crash dump from the logs, and the GlusterFS
client logs (produced by the `vfs_glusterfs.so` module in SMBD).

I'm using Ubuntu 16.04.3 with samba package
2:4.3.11+dfsg-0ubuntu0.16.04.12 (I locally recompiled
`samba-vfs-modules` to enable the GlusterFS VFS which is by default
disabled in Ubuntu builds).

Any suggestions on what/where to look?

Alternatively: how to improve the performance of SAMBA over
locally-mounted GlusterFS? right now, I'm getting a 2x to 4x slowdown
compared to SAMBA with local disk.

Thanks for any help!

Riccardo

[Gluster-users] SAMBA VFS module for GlusterFS crashes

Keep in mind a local disk is 3,6,12 Gbps but a network connection is typically
1Gbps. A local disk quad in raid 10 will outperform a 10G ethernet (especially
using SAS drives).

[Gluster-users] SAMBA VFS module for GlusterFS crashes

Hi John,

thanks for your remark. However:

2017-12-05 16:47 GMT+01:00 Jim Kinney <jim.kinney at
gmail.com>:> Keep in mind a local disk is 3,6,12 Gbps but a network connection is

Well, in this case all servers (both GlusterFS and SAMBA) are running
on VMs whose storage
is in a Ceph cluster -- so "local disk" really means an RBD volume
over 10Gb/s ethernet...

(I know that it makes little sense to run GlusterFS over Ceph storage,
but that's what we have and I cannot serve RBD volumes from Ceph
directly unless they're attached to some VM...)

Ciao,
R

I think you are hitting a bug[1] from vfs module for GlusterFS inside Samba
during a realpath()
call.

This regression got in when glfs_realpath() was modified in GlusterFS[2] to
correctly handle memory
allocation and corresponding freeing of string arguments. And this particular
change is present from
 GlusterFS version 3.7.17 in 3.7 series, in 3.9 series and all above versions
(but not present in
3.8 series).

So if you are using any of the above mentioned GlusterFS versions(which contains
the above change
for glfs_realpath()), then you are recommended to install Samba version >=
4.4.9 in 4.4 series, >4.5.2 or any versions from higher series like 4.6, 4.7
etc which contains the fix for this crash.

We had this mentioned in release notes for GlusterFS v3.7.17[3].

I would suggest you to upgrade both Samba and GlusterFS to supported versions as
per [4] and [5].

[Gluster-users] SAMBA VFS module for GlusterFS crashes

Dear Anoop,

thank you very much for your detailed explanation.
> I think you are hitting a bug[1] from vfs module for GlusterFS inside Samba
during a realpath()
> call.
>
> This regression got in when glfs_realpath() was modified in GlusterFS[2] to
correctly handle memory
> allocation and corresponding freeing of string arguments. And this
particular change is present from
>  GlusterFS version 3.7.17 in 3.7 series, in 3.9 series and all above
versions (but not present in
> 3.8 series).

contains the above change

>= 4.4.9 in 4.4 series, >> 4.5.2 or any versions from higher series
like 4.6, 4.7 etc which contains the fix for this crash.
I'm using GlusterFS 3.12.3 from the GlusterFS Ubuntu PPA [1]::

    $ apt-cache policy glusterfs-client
    glusterfs-client:
      Installed: 3.12.3-ubuntu1~xenial1
      Candidate: 3.12.3-ubuntu1~xenial1
      Version table:
     *** 3.12.3-ubuntu1~xenial1 500
            500 http://ppa.launchpad.net/gluster/glusterfs-3.12/ubuntu
xenial/main amd64 Packages
            100 /var/lib/dpkg/status
         3.7.6-1ubuntu1 500
            500 http://nova.clouds.archive.ubuntu.com/ubuntu xenial/universe
amd64 Packages
            500 http://archive.ubuntu.com/ubuntu xenial/universe amd64 Packages

So this should contain the fix already?  Or is the fix Samba-side?

[1] https://launchpad.net/~gluster/+archive/ubuntu/glusterfs-3.12

Thanks,
Riccardo
