[Gluster-users] quota calculation gluster 3.2.3

Fri Sep 2 08:19:00 UTC 2011

I've done a ls -lRa throught the mount point and now i get : 
/soft/venus # gluster volume quota venus list
    path          limit_set         size
----------------------------------------------------------------------------------
/                           2GB                1.3GB
/test                     100MB                8.0KB
/psa                      200MB              151.0MB
/soft                    1500MB              826.3MB

=>Seems to be consistent

and now command  getfattr on yval1000 and yval1010 show : 

yval1000 : 
getfattr -n trusted.glusterfs.quota.size -e hex /soft/venus/   
trusted.glusterfs.quota.size=0x0000000028f9ca00

getfattr -n trusted.glusterfs.quota.size -e hex /soft/venus/soft
trusted.glusterfs.quota.size=0x000000001421d400

getfattr -n trusted.glusterfs.quota.size -e hex /soft/venus/psa
trusted.glusterfs.quota.size=0x00000000053d6000

yval1010 : 
getfattr -n trusted.glusterfs.quota.size -e hex /soft/venus/   
trusted.glusterfs.quota.size=0x000000002904ea00

getfattr -n trusted.glusterfs.quota.size -e hex /soft/venus/soft
trusted.glusterfs.quota.size=0x000000002292ba00

getfattr -n trusted.glusterfs.quota.size -e hex /soft/venus/psa
trusted.glusterfs.quota.size=0x00000000053d6000

I forgot to check on the 2 other server.
So ylal3020 and ylal3030 show similar output send previously.

But yval1000 and yval1010 show with all command :
 trusted.glusterfs.quota.size=0x0000000000000000

Is it normal ?

Hi Junaid,

Here is the output of the diffrent command executed on both server.
Command show identical output on both server

# getfattr -n trusted.glusterfs.quota.size -e hex /soft/venus
getfattr: Removing leading '/' from absolute path names
# file: soft/venus
trusted.glusterfs.quota.size=0x0000000022ccac00

 # getfattr -n trusted.glusterfs.quota.size -e hex /soft/venus/test
getfattr: Removing leading '/' from absolute path names
# file: soft/venus/test
trusted.glusterfs.quota.size=0x0000000000000000

 # getfattr -n trusted.glusterfs.quota.size -e hex /soft/venus/psa     
getfattr: Removing leading '/' from absolute path names

 # getfattr -n trusted.glusterfs.quota.size -e hex /soft/venus/soft
getfattr: Removing leading '/' from absolute path names
# file: soft/venus/soft
trusted.glusterfs.quota.size=0x000000000d15ce00

# gluster volume quota venus list
    path          limit_set         size

/                           2GB              556.8MB
/test                     100MB               0Bytes
/psa                      200MB                1.2MB
/soft                    1500MB              209.4MB

Indeed there is 90% of small file (~60000 files).

Thx

Anthony

Hi Anthony,
To debug this further, can you send the output of 
getfattr -n trusted.glusterfs.quota.size -e hex /soft/venusgetfattr -n trusted.glusterfs.quota.size -e hex /soft/venus/test

getfattr -n trusted.glusterfs.quota.size -e hex /soft/venus/psagetfattr -n trusted.glusterfs.quota.size -e hex /soft/venus/soft

from both the machine. Also check the output of
gluster volume quota Replicate list

Sometimes it takes a small amount of time to bring up the sizes. Also, what kind of data where you creating (I mean large amount of small files or large files because in case of small files, the directory sizes are not accounted by quota to calculate the size unlike the du -h command which uses the directory size as well).

Hi all,

I've enable quota but I'm a bit confused by values displayed by GlusterFS

Here is my volume : 

Volume Name: venus
Type: Replicate
Status: Started
Number of Bricks: 2
Transport-type: tcp

Bricks:
Brick1: ylal3020:/soft/venus
Brick2: ylal3030:/soft/venus
Options Reconfigured:
features.limit-usage: /test:100MB,/psa:200MB,/soft:1500MB,/:2GB
features.quota: on
diagnostics.client-log-level: ERROR

diagnostics.brick-log-level: ERROR
network.ping-timeout: 10
performance.cache-size: 2GB
nfs.port: 2049

I've got 3 folders in the backend (/soft/venus) : 
psa        160MB  (with du -sh)
soft         1.2GB

test         12KB
Total       1.4GB

But when I list the quota with gluster I got : 
# gluster volume quota venus list
    path          limit_set         size
----------------------------------------------------------------------------------

/test                     100MB               12.0KB                  <= This one is OK
/psa                      200MB               64.4MB           <= not OK
/soft                    1500MB              281.8MB           <= not OK

/                           2GB              346.2MB               <= not OK

Any idea ?

Regards,

Anthony Garnier
