Hi,
I am just looking through my logs and am seeing a lot of entries of the form:
[2015-03-16 16:02:55.553140] I
[glusterd-handler.c:3530:__glusterd_handle_status_volume] 0-management:
Received status volume req for volume wiki
[2015-03-16 16:02:55.561173] E
[glusterd-utils.c:5140:glusterd_add_inode_size_to_dict] 0-management: tune2fs
exited with non-zero exit status
[2015-03-16 16:02:55.561204] E
[glusterd-utils.c:5166:glusterd_add_inode_size_to_dict] 0-management: failed to
get inode size
Having had a rummage I *suspect* it is because gluster is trying to get the
volume status by querying the superblock on the filesystem for a brick volume.
However this is an issue as when the volume was created it was done so in the
form:
root@gfsi-rh-01:/mnt# gluster volume create gfs1 replica 2 transport tcp \
gfsi-rh-01:/srv/hod/wiki \
gfsi-isr-01:/srv/hod/wiki force
Where the those paths to the bricks are not the raw paths but instead are paths
to the mount points on the local server.
Volume status returns:
gluster volume status wiki
Status of volume: wiki

Task Status of Volume wiki
------------------------------------------------------------------------------
There are no active volume tasks
Which is what I would expect.
Interestingly to check my thoughts:
# tune2fs -l /srv/hod/wiki/
tune2fs 1.42.5 (29-Jul-2012)
tune2fs: Attempt to read block from filesystem resulted in short read while
trying to open /srv/hod/wiki/
Couldn't find valid filesystem superblock.
Does what I expect as it is checking a mount point and is what it looks like
gluster is trying to do.
But:
# tune2fs -l /dev/mapper/bricks-wiki
tune2fs 1.42.5 (29-Jul-2012)
Filesystem volume name: wiki
Last mounted on: /srv/hod/wiki
Filesystem UUID: a75306ac-31fa-447d-9da7-23ef66d9756b
Filesystem magic number: 0xEF53
Filesystem revision #: 1 (dynamic)
Filesystem features: has_journal ext_attr resize_inode dir_index filetype

dir_nlink extra_isize
Filesystem flags: signed_directory_hash
Default mount options: user_xattr acl
Filesystem state: clean
<snipped>
This leaves me with a couple of questions:
Is there any way that I can get this sorted in the gluster configuration so
that it actually checks the raw volume rather than the local mount point for
that volume?
Should the volume have been created using the raw path /dev/mapper/.....
rather than the mount point?
Or should I have created the volume (as I *now* see in the RedHat Storage Admin
Guide) - under a sub directrory directory below the mounted filestore (ie:
/srv/hod/wiki/brick ?
If I need to move the data and recreate the bricks it is not an issue for me as
this is still proof of concept for what we are doing, what I need to know
whether doing so will stop the continual log churn.
Many thanks
Paul
