Subject pretty much says it all.
For testing purposes I tried to disable barriers in fstab (barriers=0). On
reboot the filesystem will not mount read/write until barriers are reenabled.
This occurs whether I use ordered data mode or data writeback mode, in both
Gentoo and Slackware 12.1
Is this behavior by design (that barriers can not be disabled)?
Thanks,
Gary

What errors do you get?

Hm, it's not supposed to be :)
Perhaps you just spelled it wrong:
root@inode ~]# mount -o barriers=0 /dev/sdb2 /mnt/test
mount: wrong fs type, bad option, bad superblock on /dev/sdb2,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
[root@inode ~]# mount -o barrier=0 /dev/sdb2 /mnt/test
[root@inode ~]#
