Hi,

There was a power outage and I had to restart my solaris machine: 
SunOS mymachine 5.7 Generic_106541-18 sun4u sparc SUNW,Ultra-5_10

Now whan I attempt to make any write on the /usr drive I get the
following type of message:
cp: cannot create ../mc3.tar: Read-only file system

Here is the line in my vfstab file:
/dev/dsk/c0t0d0s7       /dev/rdsk/c0t0d0s7      /usr    ufs     1     
 no      -

Here is the corresponding line in the mnttab file:
/dev/dsk/c0t0d0s7       /usr    ufs     ro,suid,dev=2200007,largefiles
 1112694631

Any ideas on this one.
Enda

change:
/dev/dsk/c0t0d0s7       /usr    ufs RW,suid,dev=2200007,largefiles 
1112694631
reboot now.

ro says read-only filesystem

and the "no" in vfstab line says "no mount in boot time"
man vfstab
man mount

The filesystem might have been corrupted.  Try to "fsck" and remount "rw"

You might want to add "logging" to the mount options (man mount_ufs).
You might have to patch up the system first (I think "logging" was added
in a kernel patch of SunOS 5.7).  Apply the latest Recommended Patch Cluster

do not edit mnttab

Which is correct for / and /usr - do not change it

d.

your rtfm suggestion did not work, I had exhausted that particular
avenue already.

What fixed my problem was running the following command during startup
console mode (or whatever its called).
fsck -F ufs /dev/rdsk/c0t0d0s7

Thanks all for help and suggestions.
