"Mad Unix"
 
Default wrong FS

I am running RHEL5 (2.6.18-53.el5) with EMCpowerpath.

I can do mount /dev/emc_vg/emc_lv /test, But if I reboot the node and try
mounting the filesystem
it shows


[root@linux2 ~]# mount -a
mount: wrong fs type, bad option, bad superblock on /dev/emc_vg/emc_lv,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so


[root@linux2 ~]# dmesg | tail
