Re: failed to get inode size in gluster log

[Claudio Kuenzler <ck@xxxxxxxxxxxxxxxxxxx>]

Hey Kaleb,

Thanks for your response.

Yes, the brick fs is ext4 (therefore the log entries "0-management: tune2fs exited with non-zero exit status").

e2fsprogs package is installed. tune2fs command is also available.

By the way, I forgot to mention the version:

glusterfs 3.4.2

Ubuntu 14.04 LTS

What exactly is the glusterfs daemon trying to do? Does it just want to get the information of how many inodes there are on the brick with "tune2fs -l $brick"?

If yes, then the issue is most likely a permission issue.
We're running the glusterfs daemon within an LXC container. The LV is directly mounted into the container (through the fstab config file in /var/lib/lxc/lxcname/fstab).
Within the LXC, tune2fs doesn't work and returns "1":

# tune2fs -l /dev/lxc1/storage03-brick
tune2fs 1.42.9 (4-Feb-2014)
tune2fs: No such file or directory while trying to open /dev/lxc1/storage03-brick
Couldn't find valid filesystem superblock.
# echo $?
1

When I run the same on the physical server, the tune2fs command works:

# tune2fs -l /dev/lxc1/storage03-brick
tune2fs 1.42.9 (4-Feb-2014)
Filesystem volume name:   <none>
Last mounted on:          /usr/lib/x86_64-linux-gnu/lxc
Filesystem UUID:          18f84853-4070-4c6a-af95-efb27fe3eace

[...]

Thanks for pointing me in the right direction :).

cheers

You probably need to add xfsprogs (rpm) or the dpkg equivalent, assuming your brick is an xfs volume.

Or if the brick is ext4, then you need to install e2fsprogs.

-------------- end snipp ------------

On my research I came across a source code commit
(https://forge.gluster.org/glusterfs-core/glusterfs/commit/3f81c44a03e9ab78be2b4a69e3e36d41a4de324a/diffs?diffmode=sidebyside&fragment=1)
where the inode size from different fs types is retreived (glusterd:
Used runner's RUN_PIPE to get inode size in xfs/ext3/ext4).

Is the gluster management doing this because of the received heal
request (Received status volume req for volume applications)?

As these are errors, I worry about the consistency of the glusterfs
volume. Anyone having had a similar issue?

Thanks,
Claudio
