Hi!
Using Lustre 1.6.4.1 it''s still not possible to set quotas to larger
values than approx 4TB. 2^32 (4294967296) and above are silently
truncated to the lower 32 bits.
Is a fix underway? Since it''s a rather obvious bug it
shouldn''t take
that long to fix IMHO.

Not as straightforward as you might think. Johann

I thought everything in lustre was 64bit already. /Nikke -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Niklas Edmundsson, Admin @ {acc,hpc2n}.umu.se | nikke at hpc2n.umu.se --------------------------------------------------------------------------- Jimmy Hoffa is buried here ------> X =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

I thought everything in lustre was 64bit already.The lustre quota files are now 64bit (the format conversion will be handled transparently in 1.4.12/1.6.5). Unfortunately, the linux kernel does not support quotas > 4TB. As a consequence, quota limits > 4TB work only with OSTs smaller than 4TB for now. A kernel patch is under development in bug 13904.
