[Lustre-discuss] Incorrect user's Quota

[Lu Wang]

Hi Yong,

     We are running lustre-1.6.5-2.6.9_55.EL.cernsmp 32 bit(on client), 2.6.9-67.0.22.EL_lustre.1.6.6smp,64bit(on server).
each user has 20GB quota for file size. We have not set file number quota. 

#  lfs quota -u **** /besfs2
Disk quotas for user **** (uid 23034):
     Filesystem  kbytes   quota   limit   grace   files   quota   limit   grace
        /besfs2       4  20000000 20100000               1       0       0        
besfs2-MDT0000_UUID
                      4          131072               1               0        
besfs2-OST0000_UUID
                      0          131072

                      0          131072        
besfs2-OST0002_UUID
                      0          131072        
besfs2-OST0003_UUID
                      0          131072        
besfs2-OST0004_UUID
                      0          131072        
besfs2-OST0005_UUID
                      0          131072        
besfs2-OST0006_UUID
                      0          131072   

 I am sorry I do not have the error screen shot.  Which shows that certain user has not reached the file size quota while 
an "quota exceed" error was triggered.

Which version of lustre you used? What is the "Quota exceed" for: block 
or file? What is the limitation for your users quota? Provide detail 
information can help to localization the issues.
