> The filesystems are XFS over LVM over RAID5 and served out via NFS and SAMBA.
I too have seen unexplained failures on recent Fedora (6, 7, and 8) systems which also used XFS over LVM over hardware RAID 5 and served out via NFS. The systems halt, and you can do nothing to bring them back. Sometimes, it's even impossible to reboot, and other times the data on the usually very large XFS file system is irrecoverable. The problem disappears when you stop using the LVM. It's not that the LVM is faulty, but it seems that the combination of XFS over LVM leads to a stack overflow in the kernel. It is annoying to not have the benefits of the LVM -- e.g. the fiction of a large, flat, file system -- but XFS alone, without LVM, over many small, RAID 5, over disc volumes of a few terabytes each, is stable and preferable to having to reload a filesystem with terabytes of data. -- kernel OOM crash on lightly loaded server with 4GB of RAM https://bugs.launchpad.net/bugs/231992 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
