should I be able to get something out of either 'gdb /sbin/fsck <pid>' or
'truss -p <pid>' for an fsck process?

I tried truss -p, and it just sits there ... and gdb shows:

jupiter# gdb /sbin/fsck 361

I'm up to a 3.5hr fsck on a 100gb file system, and am worried it might
have stalled or soething, since all I have on the screen is:

jupiter# fsck -y /dev/da0s1h
** /dev/da0s1h
** Last Mounted on /vm
** Phase 1 - Check Blocks and Sizes
** Phase 2 - Check Pathnames
** Phase 3 - Check Connectivity
** Phase 4 - Check Reference Counts

Now, CPU usage seems to be continuing to climb, according to ps:

jupiter# !ps
ps aux | grep fsck
root      361 99.0  2.3 95572 95500  p0  R+    4:21PM 206:19.31 fsck -y /dev/da0s1h
jupiter# !ps
ps aux | grep fsck
root      361 99.0  2.3 95572 95500  p0  R+    4:21PM 206:23.51 fsck -y /dev/da0s1h

so I'm guessing that it is still working fine, and I'm being paranoid, but
... ?

thanks ...
