Hi,
        I am having a quota issue with Lustre. Here are the default limits 
set for an account - 
/home   0  400000  450000             189  100000  100000
        This sets a quota of about 300 MB or so. After reading the 
documenatation, i throught this would have set ~4 G or so, but it is one 
zero less. The quota limit is working though.
	But today i found the following issue with two accounts. The 
account goes over quota showing higher block utilization, while the real 
space occupied by the account is only a few megabytes on the filesystem.
Here is an example -
     Filesystem  blocks   quota   limit   grace   files   quota   limit
grace
          /home  307796  600000  650000             221  100000  100000
home-MDT0000_UUID
                    316       0  102400             221       0    5000
home-OST0000_UUID
                 307480       0  409600> du -sh ../username/
3.8M    ../username/
 
In the Lustre server, there are quite a few of the following error 
messages -
Jul 24 01:31:09 lustre-3ware kernel: LustreError: 
3659:0:(fsfilt-ldiskfs.c:1962:fsfilt_ldiskfs_dquot()) Skipped 11 previous

Hi,
              There are a few further messages on the Lustre server  
like this -
Jul 24 08:25:35 lustre-3ware kernel: Lustre: Found inode with zero 
generation or link -- this may indicate disk corruption (inode: 
10251612/839130903, link 0, count 1)

           This is preceded by lots of the following error messages -
Jul 24 01:31:24 lustre-3ware kernel: LustreError: 
3654:0:(ldlm_lib.c:1554:target_handle_dqacq_callback()) dqacq failed! 
(rc:-5)
           The data on the volumes is fine. Is the disk corruption error 
related to the quota problem or is this a new issue? The 3ware raid 
volume is working fine. Thanks very much.
