Hi Mauro, Can you send the gluster v status command output? Is it a single volume that is spread between all the 3 node and has 36 bricks? If yes, you will have to run on all the bricks. In the command use sub-dir option if you are running only for the directory where limit is set. else if you are running on the brick mount path you can remove it. The full-log will consume a lot of space as its going to record the xattrs for each entry inside the path we are running it. This data is needed to cross check and verify quota's marker functionality. To reduce resource consumption you can run it on one replica set alone (if its replicate volume) But its better if you can run it on all the brick if possible and if the size consumed is fine with you. Make sure you run it with the script link provided above by Sanoj. (patch set 6) On Tue, Jul 10, 2018 at 2:54 PM Mauro Tridici < mauro.tridici@xxxxxxx> wrote:
Hi Hari,
thank you very much for your answer.
I will try to use the script mentioned above pointing to each backend bricks.
So, if I understand, since I have a gluster cluster composed by 3 nodes (with 12 bricks on each node), I have to execute the script 36 times. Right?
You can find below the “df” command output executed on a cluster node:
/dev/mapper/cl_s01-gluster 100G 33M 100G 1% /gluster
/dev/mapper/gluster_vgd-gluster_lvd 9,0T 5,6T 3,5T 62% /gluster/mnt2
/dev/mapper/gluster_vge-gluster_lve 9,0T 5,7T 3,4T 63% /gluster/mnt3
/dev/mapper/gluster_vgj-gluster_lvj 9,0T 5,7T 3,4T 63% /gluster/mnt8
/dev/mapper/gluster_vgc-gluster_lvc 9,0T 5,6T 3,5T 62% /gluster/mnt1
/dev/mapper/gluster_vgl-gluster_lvl 9,0T 5,8T 3,3T 65% /gluster/mnt10
/dev/mapper/gluster_vgh-gluster_lvh 9,0T 5,7T 3,4T 64% /gluster/mnt6
/dev/mapper/gluster_vgf-gluster_lvf 9,0T 5,7T 3,4T 63% /gluster/mnt4
/dev/mapper/gluster_vgm-gluster_lvm 9,0T 5,4T 3,7T 60% /gluster/mnt11
/dev/mapper/gluster_vgn-gluster_lvn 9,0T 5,4T 3,7T 60% /gluster/mnt12
/dev/mapper/gluster_vgg-gluster_lvg 9,0T 5,7T 3,4T 64% /gluster/mnt5
/dev/mapper/gluster_vgi-gluster_lvi 9,0T 5,7T 3,4T 63% /gluster/mnt7
/dev/mapper/gluster_vgk-gluster_lvk 9,0T 5,8T 3,3T 65% /gluster/mnt9
I will execute the following command and I will put here the output.
./quota_fsck_new.py --full-logs --sub-dir /gluster/mnt{1..12}
Thank you again for your support.
Regards,
Mauro

Hi,
There is no explicit command to backup all the quota limits as per my
understanding. need to look further about this.
But you can do the following to backup and set it.
Gluster volume quota volname list which will print all the quota
limits on that particular volume.
You will have to make a note of the directories with their respective limit set.
Once noted down, you can disable quota on the volume and then enable it.
Once enabled, you will have to set each limit explicitly on the volume.
Before doing this we suggest you can to try running the script
mentioned above with the backend brick path instead of the mount path.
you need to run this on the machines where the backend bricks are
located and not on the mount.

Hi Sanoj,
could you provide me the command that I need in order to backup all quota limits?
If there is no solution for this kind of problem, I would like to try to follow your “backup” suggestion.
Do you think that I should contact gluster developers too?
Thank you very much.

Mauro

Hi Sanoj,
unfortunately the output of the command execution was not helpful.
[root@s01 ~]# find /tier2/CSP/ans004 | xargs getfattr -d -m. -e hex
[root@s01 ~]#
Do you have some other idea in order to detect the cause of the issue?
Thank you again,

Hi Mauro,
A script issue did not capture all necessary xattr.
Could you provide the xattrs with..
find /tier2/CSP/ans004 | xargs getfattr -d -m. -e hex
Meanwhile, If you are being impacted, you could do the following
back up quota limits
disable quota
enable quota
freshly set the limits.
Please capture the xattr values first, so that we can get to know what went wrong.
Regards,
Sanoj

Dear Sanoj,
thank you very much for your support.
I just downloaded and executed the script you suggested.
This is the full command I executed:
./quota_fsck_new.py --full-logs --sub-dir /tier2/CSP/ans004/ /gluster
In attachment, you can find the logs generated by the script.
What can I do now?
Thank you very much for your patience.

Hi Mauro,
This may be an issue with update of backend xattrs.
To RCA further and provide resolution could you provide me with the logs by running the following fsck script.
https://review.gluster.org/#/c/19179/6/extras/quota/quota_fsck.py
Try running the script and revert with the logs generated.
Thanks,
Sanoj

Dear Users,
I just noticed that, after some data deletions executed inside "/tier2/CSP/ans004” folder, the amount of used disk reported by quota command doesn’t reflect the value indicated by du command.
Surfing on the web, it seems that it is a bug of previous versions of Gluster FS and it was already fixed.
In my case, the problem seems unfortunately still here.
How can I solve this issue? Is it possible to do it without starting a downtime period?
Thank you very much in advance,
Mauro
