Lustre discuss - Aug 2007 - lustre 1.6.1 and quota problems

Hi,

We are trying to configure quota on our lustre file system following  
lustre operation manual, but it doesn''t work

[root@node-b03 ~]# lfs df
UUID                 1K-blocks      Used Available  Use% Mounted on
home-md-MDT0000_UUID 286696376  17358196 269338180    6% /home[MDT:0]
home-md-OST0001_UUID 6044496232 1733800804 4310695428   28% /home[OST:1]

filesystem summary:  6044496232 1733800804 4310695428   28% /home

[root@node-b03 ~]# lfs quotacheck -ug /home
quotacheck failed: Input/output error

If anyone ever configured quota on lustre 1.6.1 could you tell us how  
to do that or point us to comprehensive documentation?

Best regards

Wojciech Turek

I forgot to say that lquota module is loaded

[root@node-b03 ~]# lsmod | grep lquota
lquota                114192  3
ptlrpc                616008  6 osc,mgc,lustre,lov,mdc,lquota
obdclass              505256  8 osc,mgc,lustre,lov,mdc,lquota,ptlrpc
lvfs                   51848  8  
osc,mgc,lustre,lov,mdc,lquota,ptlrpc,obdclass
libcfs                115544  11

The reference documentation regarding quotas is here:
http://manual.lustre.org/manual/LustreManual16_HTML/DynamicHTML-09-1.html

Your first step looks correct to me. Have you checked that the lquota 
module is loaded on both your MDS and OSS(es) too?

Another thing, although I''m not sure it''s related or not: the
only OST
listed in your df output is numbered as OST0001, whilst it should 
probably be OST0000. Are all your OST active? What is the output of 
a ''lctl dl''? And do you have any message in dmesg when you run
''lfs
quotacheck''?

Cheers,
