Re: "file changed as we read it" in gluster 3.7.4

Thank you, this solved the issue (after a umount/mount). The question now is: what's the catch? Why is this not the default?

https://partner-bugzilla.redhat.com/show_bug.cgi?id=1203122

The above link makes me think that there is a problem with "readdirp" performances but I'm not sure if the impact is serious or not.

#gluster volume set <VOL> cluster.consistent-metadata on

SUBJECT:  "file changed as we read it" in gluster
3.7.4

Hello,

I'm evaluating gluster on Debian, I installed the version 3.7.4 and
I
see this kind of error messages when I run tar:

# tar c linux-3.16.7-ckt11/ > /dev/null
tar: linux-3.16.7-ckt11/sound/soc: file changed as we read it

I saw this problem was discussed here earlier but I was under the
impression it was resolved on the 3.5 series. Is the fix in the 3.7
branch?

My volume configuration:

# gluster volume info glustervol1

Volume Name: glustervol1
Type: Replicate
Volume ID: 71ce34f2-28da-4674-91c9-b19a2b791aef
Status: Started
Number of Bricks: 1 x 3 = 3
Transport-type: tcp
Bricks:
Brick1: n1:/glusterfs/n1-2/brick
Brick2: n2:/glusterfs/n2-2/brick
Brick3: n3:/glusterfs/n3-2/brick
Options Reconfigured:
performance.readdir-ahead: on
cluster.server-quorum-ratio: 51
