As per an earlier email you have already run a fix-layout.Yes, we added new bricks to the volume and we already executed fix-layout before.> On s04, please check the rebalance log file to see why the rebalance failed.On s04, rebalance failed after the following errors (before these lines no errors were found): [2018-10-06 00:13:37.359634] I [MSGID: 109063] [dht-layout.c:716:dht_layout_normalize] 0-tier2-dht: Found anomalies in / (gfid = 00000000-0000-0000-0000-000000000001).

[Gluster-users] Rebalance failed on Distributed Disperse volume based on 3.12.14 version
Hi Mauro,
What is the status of rebalace now?
Could you please give output of following for all the bricks -
getfattr -m. -d -e hex <root path of athe brick>
You have to go to all the nodes and for all the bricks on that node you have to
run above command.
Example: on s01
getfattr -m. -d -e hex /gluster/mnt1/brick
Keep output from one node in one file si that it will be easy to analyze.

Hi Nithya,
thank you, my answers are in lines.

Hi Mauro,
Yes, a rebalance consists of 2 operations for every directory:
1. Fix the layout for the new volume config (newly added or removed bricks)
2. Migrate files to their new hashed subvols based on the new layout
Are you running a rebalance because you added new bricks to the volume ? As per
an earlier email you have already run a fix-layout.
Yes, we added new bricks to the volume and we already executed fix-layout
before.
<blockquote>
On s04, please check the rebalance log file to see why the rebalance failed.
</blockquote>
On s04, rebalance failed after the following errors (before these lines no

Rebalance is migrating files on s05, s06 servers and on s04 too (although it is
marked as failed).
s05 and s06 tasks are completed.
Questions:
1) it seems that rebalance is moving files, but it is fixing the layout also, is
it normal?
2) when rebalance will be completed, what we need to do before return the
gluster storage to the users? We have to launch rebalance again in order to
involve s04 server too or a fix-layout to eventually fix some error on s04?
Thank you very much,
Mauro

Hi All,
some important updates about the issue mentioned below.
After rebalance failed on all the servers, I decided to:
- stop gluster volume
- reboot the servers
- start gluster volume
- change some gluster volume options
- start the rebalance again
The options that I changed are listed below after reading some threads on
gluster users mailing list:
BEFORE CHANGE:
gluster volume set tier2 network.ping-timeout 02
gluster volume set all cluster.brick-multiplex on
gluster volume set tier2 cluster.server-quorum-ratio 51%
gluster volume set tier2 cluster.server-quorum-type server
gluster volume set tier2 cluster.quorum-type auto
AFTER CHANGE:
gluster volume set tier2 network.ping-timeout 42
gluster volume set all cluster.brick-multiplex off
gluster volume set tier2 cluster.server-quorum-ratio none
gluster volume set tier2 cluster.server-quorum-type none
gluster volume set tier2 cluster.quorum-type none
The result was that rebalance starts moving data from s01, s02 ed s03 servers to
s05 and s06 servers (the new added ones), but it failed on s04 server after 37
seconds.
The rebalance is still running and moving data as you can see from the output:

When rebalance will be completed, we are planning to re-launch it to try to
involve s04 server also.
Do you have some idea about what happened in my previous message and why, now,
rebalance it?s running although it?s not involve s04 server?
In attachment the complete tier2-rebalance.log file related to s04 server.
Thank you very much for your help,

Hi All,
since we need to restore gluster storage as soon as possible, we decided to
ignore the few files that could be lost and to go ahead.
So we cleaned all bricks content of servers s04, s05 and s06.
As planned some days ago, we executed the following commands:
gluster peer detach s04
gluster peer detach s05
gluster peer detach s06
gluster peer probe s04
gluster peer probe s05
gluster peer probe s06

In attachment you can find the first logs captured during the rebalance
execution.
In your opinion, is there a way to restore the gluster storage or all the data
have been lost?
Thank you in advance,
Mauro

Hi Mauro,
The files on s04 and s05 can be deleted safely as long as those bricks have been
removed from the volume and their brick processes are not running.
.glusterfs/indices/xattrop/xattrop-* are links to files that need to be healed.
.glusterfs/quarantine/stub-00000000-0000-0000-0000-000000000008 links to files
that bitrot (if enabled)says are corrupted. (none in this case)
I will get back to you on s06. Can you please provide the output of gluster
volume info again?
Regards,
Nithya

Dear Ashish, Dear Nithya,
I?m writing this message only to summarize and simplify the information about
the "not migrated? files left on removed bricks on server s04, s05 and s06.
In attachment, you can find 3 files (1 file for each server) containing the ?not
migrated? files lists and related brick number.
In particular:
* s04 and s05 bricks contain only not migrated files in hidden directories
?/gluster/mnt#/brick/.glusterfs" (I could delete them, doesn?t it?)
* s06 bricks contain
* not migrated files in hidden directories
?/gluster/mnt#/brick/.glusterfs?;
* not migrated files with size equal to 0;
* not migrated files with size greater than 0.
I think it was necessary to collect and summarize information to simplify your
analysis.
Thank you very much,
Mauro
