Ran into a confusing situation today. When I mount an xfs filesystem on a server running centos 5.4 x86_64 with kernel 2.6.18-164.9.1.el5, the barrier/nobarrier mount option as displayed in /proc/mounts is always set to "nobarrier"
Here's an example: [r...@host ~]# mount -o nobarrier /dev/vg1/homexfs /mnt [r...@host ~]# grep xfs /proc/mounts /dev/vg1/homexfs /mnt xfs rw,attr2,nobarrier,noquota 0 0 [r...@host ~]# mount | grep xfs /dev/mapper/vg1-homexfs on /mnt type xfs (rw,nobarrier) [r...@host ~]# mount -o barrier /dev/vg1/homexfs /mnt [r...@host ~]# grep xfs /proc/mounts /dev/vg1/homexfs /mnt xfs rw,attr2,nobarrier,noquota 0 0 [r...@host ~]# mount | grep xfs /dev/mapper/vg1-homexfs on /mnt type xfs (rw,barrier) Can anyone else confirm this behavior?
