My mistake. That is not yet the case, but the plan for the future. Thanks for pointing that out. > No surprise if you are running an i686 kernel (32 bit).

If a 32bit kernel is not supposed to work because of the number of inodes, why does the 2.6.39.4-kernel work flawlessy on quota-checks on the same filesystem a 3.6.0-rc5 32bit (which is supposed to work) fails on? Doesn't that imply, that the fix submitted for 2.6.39.4 fixed a problem which was "reinvented" by the later patch, which is now being worked around by using a 64bit kernel for more memory? > Running on a x86-64 kernel will make the vmalloc problem go away. > There's very little we can do about the limited vmalloc address > space on i686 kernels.

The current 3.6.0-rc5 in 64bit works doing the quota-check. I'll do some more testing with xfs_fsr etc. and report back. best regards volker _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
