Hi Hari,

I hope that the crawl will run at most for a couple of days.
Do you know if there is a way to solve the issue definitely ?

GlusterFS version is 3.12.14.
You can find below some additional info.

Volume Name: tier2
Type: Distributed-Disperse
Volume ID: a28d88c5-3295-4e35-98d4-210b3af9358c
Status: Started
Snapshot Count: 0
Number of Bricks: 12 x (4 + 2) = 72
Transport-type: tcp

Many thanks,
Mauro

Hi,
Yes the above mentioned steps are right.
The way to find if the crawl is still happening is to grep for
quota_crawl in the processes that are still running.
# ps aux | grep quota_crawl
As long as this process is alive, the crawl is happening.

Note: crawl does take a lot of time as well. And it happens twice.

Hi Hari,

thank you very much for the fast answer.
I think that the we will try to solve the issue disabling and enabling quota.
So, if I understand I have to do the following actions:

- save on my notes the current quota limits;
- disable quota using "gluster volume quota /tier2 disable” command;
- wait a while for the crawl (question: how can I understand that crawl is terminated!? how logn should I wait?);
- enable quota using  "gluster volume quota /tier2 enable”;
- set again the previous quota limits.

Is this correct?

Many thanks for your support,
Mauro

Hi Mauro,

The fsck script is the fastest way to resolve the issue.
The other way would be to disable quota and once the crawl for disable
is done, we have to enable and set the limits again.
In this way, the crawl happens twice and hence its slow.

Dear All,

I’m experiencing again a problem with gluster file system quota.
The “df -hT /tier2/CSP/sp1” command output is different from the “du -ms” command executed against the same folder.

[root@s01 manual]# df -hT /tier2/CSP/sp1
Filesystem     Type            Size  Used Avail Use% Mounted on
s01-stg:tier2  fuse.glusterfs   25T   22T  3.5T  87% /tier2

[root@s01 sp1]# du -ms /tier2/CSP/sp1
14TB /tier2/CSP/sp1

In the past, I used successfully the quota_fsck_new-6.py script in order to detect the SIZE_MISMATCH occurrences and fix them.
Unfortunately, the number of sub-directories and files saved in /tier2/CSP/sp1 grew so much and the list of SIZE_MISMATCH entries is very long.

Is there a faster way to correct the mismatching outputs?
Could you please help me to solve, if it is possible, this issue?

Thank you in advance,
Mauro
