Hello, after the upgrade of the kernel, I cannot mount xfs filesystems any more. I get this error: mount: Operation not supported /var/log/messages tells me: Nov 6 12:48:19 grid-se118 kernel: Filesystem "cciss/c1d0p1": Disabling barriers, not supported by the underlying device Nov 6 12:48:19 grid-se118 kernel: XFS mounting filesystem cciss/c1d0p1 Nov 6 12:48:19 grid-se118 kernel: SELinux: (dev cciss/c1d0p1, type xfs) has no security xattr handler I installed these packages: kernel-devel-2.6.18-164.6.1.el5.x86_64.rpm kernel-2.6.18-164.6.1.el5.x86_64.rpm kernel-headers-2.6.18-164.6.1.el5.x86_64.rpm kernel-module-xfs-2.6.18-164.6.1.el5-0.4-2.sl5.x86_64.rpm The problem disappears if I downgrading to the old kernel 2.6.18-128.7.1.
