Lustre discuss - Jun 2010 - default quotas

Ok I see lustre supports quotas. I have enabled them and all is good in that I
can set them for users.
 
But I cannot see any examples on how to set/adjust default quotas. Do I have to
set an individual quota for every user and group??
 
Thanks in advance,
 
Brian Andrus

Hi,

I''ve been reading about how to set-up quota allocations in the Lustre
Operations Manual 1.8.x   Section 9.1.3.

It is available on-line (although it has moved about on URL names recently).

Cheers!

Hi Brian,

Well,  Lustre, or any other file system cannot make assumptions about
a ''basic default'' quota because disk space quotas are so
dependent
upon the size of the disk mount point and the number of users sharing
the pool---so I am assuming that is not what you mean.

If you mean setting a site-wide default quota value, then yes, I''m
following here.   The quota system on the ext3 file system does have a
-p or "preen" option that allows the operator to set quotas for one
user and then to propagate that to many other users.     No, I did not
see such a tool for Lustre file system quotas.  My own usage is that I
script the initialization of quotas on Lustre filesystems.   I then
add that line to my new user procedure.  Does that better answer your
question?

If anyone on the List has better ideas, please do share them with us.
