Deep checking Solaris ufs filesystem

I'm prompted to start this thread following my attempt to help on this thread here (see my posts).

I was proposing the OP deep checked a Solaris ufs filesystem using:

Code:

 # fsck -o full <filesystem node>

however this option does not appear to be valid on Solaris 10.

I've used this option on many Unix/Linux versions over the years but, very often, it's availability not documented and often doesn't appear on man pages but is still there. I'm as sure as I can be that '-o full' was available on Solaris fsck in versions 2.51, 5.6 and 5.8 but seems its been removed on Solaris 10.

So this begs the question: How do you deep check a Solaris 10 ufs filesystem? If you want to check the superblock, every inode, allocated sectors, the check all those sectors are readable, how can you do it? What options/switches do you use so you check EVERYTHING is readable except free space.

fsck.xfs(8)                                                   System Manager's Manual                                                  fsck.xfs(8)

NAME

       fsck.xfs - do nothing, successfully

SYNOPSIS

       fsck.xfs [ filesys ... ]

DESCRIPTION

       fsck.xfs  is  called by the generic Linux fsck(8) program at startup to check and repair an XFS filesystem.  XFS is a journaling filesystem
       and performs recovery at mount(8) time if necessary, so fsck.xfs simply exits with a zero exit status.

       If you wish to check the consistency of an  XFS  filesystem,  or  repair  a  damaged  or  corrupt  XFS  filesystem,  see  xfs_check(8)  and
       xfs_repair(8).

FILES

       /etc/fstab.

SEE ALSO

       fsck(8), fstab(5), xfs(5), xfs_check(8), xfs_repair(8).
