Here you can find 10 stack trace samples from glusterd. I wait 10
seconds between each trace.

I get read-only mount within approximately 2 seconds after failed IO.

Unlikely. In your case only the afr.dirty is set, not the
afr.volname-client-xx xattr.
`gluster volume set myvolume diagnostics.client-log-level DEBUG` is right.

Hi,
I have a fresh glusterFS 3.11 installation on Ubuntu 16.04 that does not
work. I followed instructions from

Everything went well (peer connectivity, volume creation, and volume
startup, glusterfs mount). But the joy stopped
That really isnt an arbiter issue or for that matter a Gluster issue. We
have seen that with vanilla NAS servers that had some issue or another.
Arbiter simply makes it less likely to be an issue than replica 2 but in
turn arbiter is less 'safe' than replica 3.
However, in regards to Gluster
Hi,
I have a gluster cluster running with geo-replication. The volume that is being
geo-replicated is running on a LVM thin pool. The thin pool overflowed causing
a crash. I extended the thin pool LV and remounted which brought the volume
back online and healthy. When I try to restart the geo-
I remember seeing errors like "Transport endpoint not connected" in
the client logs after ping timeout even with arbiter. Arbiter does not
prevent this.
And if you end up in situation when arbiter blames the only running
brick for given file, you are doomed.

Really ? I can't see why. But I've never used arbiter so you probably
know more about this than I do.
In any case, with replica 3, never had a problem.

Hi, I believe it is not that simple. Even replica 2 + arbiter volume
with default network.ping-timeout will cause the underlying VM to
remount filesystem as read-only (device error will occur) unless you
tune mount options in VM's fstab.

Could you be able to provide the pstack dump of the glusterd process?

What he is saying is that, on a two node volume, upgrading a node will
cause the volume to go down. That's nothing weird, you really should use
3 nodes.

Hi, after many VM crashes during upgrades of Gluster, losing network

arbiter.
I once even managed to break this setup (with arbiter) due to network
partitioning - one data node never healed and I had to restore from
backups (it wa

Hi all,
I would like to ask if, and with how much success, you are using
GlusterFS for virtual machine storage.
My plan: I want to setup a 2-node cluster, where VM runs on the nodes
themselves and can be live-migrated on demand.
I have some questions:
- do you use GlusterFS for similar setup

the heal info command shows perfect consistency between nodes; that's what

How can I turn off readdirp?
I saw some solution but they don't work.
I tried server side
gluster volume vol performance.force-readdirp off
gluster volume vol dht.force-readdirp off
gluster volume vol perforamnce.read-ahead off
and in client side fuse mount
mount -t glusterfs server:/vol /mnt
Not yet. Gaurav will be taking a look at it tomorrow.

In your case for 5500 bricks cli is failing the command saying "Total brick
list is larger than a request. Can take (brick_count )".
RCA..
gluster cli while parsing the command takes the wordcount and based on that
it compares the statically initialized size as you have point out in

Same thing happens with 3.12.rc0. This time perf top shows hanging in
libglusterfs.so and below is the glusterd logs, which are different
