Lustre discuss - Sep 2010 - quick question on enabling quotas

Hello,

I''m new to lustre and I''ve got a test system set up (1.8.1.1),
I''ve run
quotacheck and quotaon (redundant??), and when I reboot the system, lustre
says that quotas are not enabled.  I enabled user/group quotas at fs creation
time.  Quotas work as expected before rebooting.

I''ve mounted the mdt/mgs and each of the osts as ldiskfs filesystems
and I can see the quota files (lquota_v2.group and lquota_v2.user).

The documentation says that there is nothing necessary to enable quotas
at mount time.  I''ve got to be missing something simple, but I
don''t
know what that is at this time.

What do I need to do to get quotas to survive a reboot?

Thanks,

-mb

Hi,

Have you placed the parameters on the MDT and each and every OST yet?
For my system (/dev/mapper devices), I used...


The mdt.quota_type parameter to the MDT disk.
tunefs.lustre --param="mdt.quota_type=ug" /dev/mapper/mdt0000

tunefs.lustre --param="ost.quota_type=ug" /dev/mapper/ost0000

...for all OSTs.    This made lustre quotas persistent on my
lustre-1.6.7.2 system.
