Has anyone tried LFS (ie >2G files support) and Ext3 together? Are there good reasons why this should/should not work? I see the RH enterprise kernel patch set specifically does not attempt both lfs and ext3, but the lfs patches themselves touch some reasonably localised parts of ext2, so I would hope (without having dived in there to test), that the ext3 changes would mirror that

Hello, the following series of patches fixes some issues with OCFS2 quotas. The first patch modifies VFS quota locking, the next patch uses the fact to simplify OCFS2 quota locking and solves a few deadlock issues. The third and the fourth patches fix another possible deadlocks in OCFS2 quota code and the last patch is a minor cleanup. Honza

...on the flock() behavior within mod_auth_cas.c. Doing some googling I found several references to FUSE and the need to use the glfs version related to flock(). I have attempted to compile each version available on the download page, but they all depend on the existence of ia_file within the struct iattr definition which the above linux kernel does not have. fuse-2.7.4glfs11/kernel/dir.c:1027: error: ?struct iattr? has no member named ?ia_file? Can someone provide guidance on how I might resolve this issue? Thank you,

i_alloc_sem has always been a bit of an odd "lock". It''s the only remaining rw_semaphore that can be released by a different thread than the one that locked it, and it''s use case in the core direct I/O code is more like a counter given that the writers already have external serialization. This series removes it in favour of a simpler counter scheme, thus getting rid

Hi, there appears to be a bug w.r.t. chown and quotas in ext3. In particular, if you "chown" a file on a filesystem with userquotas enabled, the quota charge in not transfered. ditto "chgrp" and group quotas. This happens because i_op->setattr has been redefined for files, and ext3_setattr doesn't do the DQUOT_TRANSFER like it should. I have fixed it by adding a

Do CentOS 5.4 users still have to use the RedHat preliminary kernels (http://people.redhat.com/jlayton/) for getting a NFSv4 safe kernel or have the patches been incorporated into CentosPlus kernels? Or is kernel-2.6.18-164.3.1.el5 somewhere in the queue? Thanks in advance! GS -- Gerhard Schneider Institute of Lightweight Design and e-Mail: gs at ilsb.tuwien.ac.at Structural

Hello Andrew, I patched 2.4.20 with your patch found out on http://lwn.net/Articles/17447/ and I have a big problem with: once server is booted on 2.4.20 with your patch, when I want to reboot with /sbin/reboot, server makes a Segmentation fault and it crashs. I tested it on 50-60 servers and it is the same problem. I tested kernel 2.4.20 without your patch: no problem. # uname -a Linux XXXXXX

Hi, the first four patches in this series fix locking problems in OCFS2 quota code (three of them can lead to potential deadlocks). The fifth patch reorders ip_alloc_sem for directories to be acquired before localalloc locks. Mark would you please merge these? The last two patches implement lockdep annotations for OCFS2 cluster locks. We annotate all the cluster locks except for special ones

Hello, the following patch series implements quotas for OCFS2. The patch series is based on: git://git.kernel.org/pub/scm/linux/kernel/git/mfasheh/ocfs2.git linux-next I've adressed Joel's comments, also node recovery is now fully working and I've fixed a few issues I found during my testing. So I'm currently not aware of any bugs. Please review, test, comment. Thanks.
