1. Is the /usr filesystem there at all? If you boot single user (boot cdrom -s) and mount the /usr filesystem manually (eg. under /a), what can you then see? Can you fsck the filesystem? (unmounted of course) Does it look right?
2. Perhaps the root filesystem driver configuration is screwed. Try telling the system to reconfigure on boot by using the -r switch (boot -r). What happens?
3. Perhaps the software cannot address the hardware due to a device screw up on the root filesystem. eg. /dev/dsk/c?t?d?s? do not allow the O/S to talk to the hardware. If so, you can tell it to rebuild the whole lot.
Boot single user (boot cd -s) USING THE MEDIA FOR THE O/S VERSION YOU ARE NOW RUNNING and mount your harddisk root filesystem under /a, then delete and reconstruct your disk devices:
Now check that (/a)/etc/vfstab looks right. Take your time. Use format command to view device names and partition tables (slices) of your drives (especially the /usr one giving you trouble). When you are sure vfstab is right, shutdown the system.
Now be sure to boot with the -r switch (boot -r) the first time you boot and the system will reconfigure all your disk devices and should mount /usr provided you have given the correct information to Solaris in vfstab.
Hi ,
I have a filesystem on AIX 4.3.3 which i need to share with other clients who use Windows NT and Redhat linux 7.3.

vfstab - table of file system defaults
DESCRIPTION
The file /etc/vfstab describes defaults for each file system. The information is stored in a table with the following column headings:
device device mount FS fsck mount mount
to mount to fsck point type pass at boot options
The fields in the table are space-separated and show the resource name (device to mount), the raw device to fsck (device to fsck), the
default mount directory (mount point), the name of the file system type (FS type), the number used by fsck to decide whether to check the
file system automatically (fsck pass), whether the file system should be mounted automatically by mountall (mount at boot), and the file
system mount options (mount options). (See respective mount file system man page below in SEE ALSO for mount options.) A '-' is used to
indicate no entry in a field. This may be used when a field does not apply to the resource being mounted.
The getvfsent(3C) family of routines is used to read and write to /etc/vfstab.
/etc/vfstab can be used to specify swap areas. An entry so specified, (which can be a file or a device), will automatically be added as a
swap area by the /sbin/swapadd script when the system boots. To specify a swap area, the device-to-mount field contains the name of the
swap file or device, the FS-type is "swap", mount-at-boot is "no" and all other fields have no entry.
EXAMPLES
The following are vfstab entries for various file system types supported in the Solaris operating environment.
Example 1: NFS and UFS Mounts
The following entry invokes NFS to automatically mount the directory /usr/local of the server example1 on the client's /usr/local directory
with read-only permission:
example1:/usr/local - /usr/local nfs - yes ro
The following example assumes a small departmental mail setup, in which clients mount /var/mail from a server mailsvr. The following entry
would be listed in each client's vfstab:
mailsvr:/var/mail - /var/mail nfs - yes intr,bg
The following is an example for a UFS file system in which logging is enabled:
/dev/dsk/c2t10d0s0 /dev/rdsk/c2t10d0s0 /export/local ufs 3 yes logging
See mount_nfs(1M) for a description of NFS mount options and mount_ufs(1M) for a description of UFS options.
Example 2: pcfs Mounts
The following example mounts a pcfs file system on a fixed hard disk on an x86 machine:
/dev/dsk/c1t2d0p0:c - /win98 pcfs - yes -
The example below mounts a Jaz drive on a SPARC machine. Normally, the volume management daemon (see vold(1M)) handles mounting of remov-
able media, obviating a vfstab entry. If you choose to specify a device that supports removable media in vfstab, be sure to set the mount-
at-boot field to no, as below. Such an entry presumes you are not running vold.
/dev/dsk/c1t2d0s2:c - /jaz pcfs - no -
For removable media on a SPARC machine, the convention for the slice portion of the disk identifier is to specify s2, which stands for the
entire medium.
For pcfs file systems on x86 machines, note that the disk identifier uses a p (p0) and a logical drive (c, in the /win98 example above) for
a pcfs logical drive. See mount_pcfs(1M) for syntax for pcfs logical drives and for pcfs-specific mount options.
Example 3: CacheFS Mount
Below is an example for a CacheFS file system. Because of the length of this entry and the fact that vfstab entries cannot be continued to
a second line, the vfstab fields are presented here in a vertical format. In re-creating such an entry in your own vfstab, you would enter
values as you would for any vfstab entry, on a single line.
device to mount: svr1:/export/abc
device to fsck: /usr/abc
mount point: /opt/cache
FS type: cachefs
fsck pass: 7
mount at boot: yes
mount options:
local-access,bg,nosuid,demandconst,backfstype=nfs,cachedir=/opt/cache
See mount_cachefs(1M) for CacheFS-specific mount options.
Example 4: Loopback File System Mount
The following is an example of mounting a loopback (lofs) file system:
/export/test - /opt/test lofs - yes -
See lofs(7FS) for an overview of the loopback file system.
