Hi Hari,
thank you very much for your support. I will do everything you suggested and I will contact you as soon as all the steps will be completed.
Thank you, Mauro
Hi Mauro, I went through the log file you have shared. I don't find any mismatch. This can be because of various reasons: 1) the accounting which was wrong is now fine. but as per your comment above if this is the case, then the crawl should still be happening which is why the its not yet reflected. (will reflect after a while) 2) the fix-issue part of the script might be wrong. 3) or the final script that we use might be wrong. You can wait for a while (based on the number of files the time will vary) and then see if the accounting is fine. If its not fine even after a while, then we will have to run the script (6th patch set has worked so can be reused) without "fix-issue" This will give us the mismatch in log file, which i can read and let you know where the lookup has to be done.

Dear Hari,
the log files that I attached to my last mail have been generated running quota-fsck script after deleting the files.
The quota-fsck script version that I used is the one in the following link https://review.gluster.org/#/c/19179/9..9/extras/quota/quota_fsck.py
I didn’t edit the log files, but during the execution I forgot to redirect the stderr and stdout to the same log file, sorry, mea culpa!
Anyway, as you suggested, I executed again the quota-fsck script with option —fix-issues.
At the end of script execution, I launched the du command, but the problem is still there.
[root@s02 auto]# df -hT /tier2/ASC/
File system Tipo Dim. Usati Dispon. Uso% Montato su
s02-stg:tier2 fuse.glusterfs 10T 2,6T 7,5T 26% /tier2
I’m sorry to bother you so much.
Last time I used the script everything went smoothly, but this time it seems to be more difficult.
In attachment you can find the new log files.
Thank you,
Mauro

Dear Hari,
I followed you suggestions, but, unfortunately, nothing is changed.
I tried to execute both the quota-fsck script with —fix-issues options both the "setfattr -n trusted.glusterfs.quota.dirty -v 0x3100” command against the files and directory mentioned by you (on each available brick).
There can be an issue with fix-issue in the script. As the directories
with accounting mismatch awre found its better to set the dirty xattr
and then do a du(this way its wasy and has to resolve the issue). The
script can be used when we dont know where the issue is.
Disk quota assigned to /tier2/ASC directory seems to be partially used (about 2,6 TB used), but the “real and current” situation is the following one (I deleted all files in primavera directory):
If the files are deleted, then state of the log file from the script
is outdated. The folders I suggested are as per the old log file, So
setting the dirty xattr and then doing a lookup (du on that dir) might
not help.
[root@s03 qc]# du -hsc /tier2/ASC/*
22G /tier2/ASC/orientgate
26K /tier2/ASC/primavera
22G totale
So, I think that the problem should be only in "orientgate” or in “primavera” directory, right!?
For this reason, in order to collect some fresh logs, I executed again the check script starting from the top level directory “ASC” using the following bash script (named hari-20180910) based on the new version of quota_fsck (rel. 9):
hari-20180910 script:
#!/bin/bash
#set -xv
host=$(hostname)
for i in {1..12}
do
./quota_fsck_r9.py --full-logs --sub-dir ASC /gluster/mnt$i/brick >> $host.log
done
~
In attachment, you can find the log files generated by the script.
SOME IMPORTANT NOTES:
- in the new log files, “primavera” directory is no more present
Is there something more that I can do?
As there were files that were deleted, the accounting would have changed again.
Need to look from the beginning, as the above suggestions may not be
true anymore.
I find that the log files are edited. A few lines are missing. Can you
send the actual log file from running the script
And i would recommend you to run the script after all the files are
deleted (or other major modifications are done).
So that we can fix once at the end.
If the fix-issue argument on script doesn't work on the directory/
subdirectory where you find mismatch, then you can send the whole
file.
Will check the log and let you know where you need to do the lookup.
Thank you very much for your patience.
Regards,
Mauro

Hi,
Looking at the logs, I can see that the file:
/orientgate/ftp/climate/3_urban_adaptation_health/6_budapest_veszprem_hungary/RHMSS_CMCC-CM_NMMB_Balkan_8km_1971-2005
/orientgate/ftp/climate/3_urban_adaptation_health/6_budapest_veszprem_hungary/RHMSS_ERA40_NMMB_Balkan_8km_1971-2000
/orientgate/ftp/climate/3_urban_adaptation_health/6_budapest_veszprem_hungary/RHMSS_CMCC-CM_NMMB-RCP8.5_Balkan_8km_2010-2100
/primavera/cam
has mismatch.
You can try setting dirty for this and then do a du on it.
A few corrections for my above comments.
The contri size in the xattr and the aggregated size have to be checked.

Hi Hari,
thank you very much for your help.
I will try to use the latest available version of quota_fsck script and I will provide you a feedback as soon as possible.
Thank you again for the detailed explanation.

Hi Mauro,
The problem might be at some other place, So setting the xattr and
doing the lookup might not have fixed the issue.
To resolve this we need to read the log file reported by the fsck
script. In this log file we need to look for the size reported by the
xattr (the value "SIZE:" in the log file) and the size reported by the
stat on the file (the value after "st_size=" ).
The contri size in the xattr and the aggregated size have to be checked
These two should be the same. If they mismatch, then we have to find
the top most dir which has the mismatch.
Bottom most dir/file has to be found. Replace top with bottom in the
following places as well.
On this top most directory you have to do a set dirty xattr and then
do a lookup.
If there are two different directories without a common top directory,
then both these have to undergo the above process.
The fsck script should work fine. can you try the "--fix-issue" with
the latest script instead of the 6th patch used above?
