Operating Systems Solaris Making sense of df -k & format verify output

so what's wrong with your "df -k" ? you could use "df -h" to see an human output but your mirror is mounted not the single slices.... that's the sense of the solaris volume manager......
/dev/md/dsk/d2, like Perderabo, said contains to same slices d0 and d1 which is c1t0d0s0 and c1t1d0s0 .....

I guess the mirror part is why I'm confused. I've never dealt with mirrored disks like this. So according to the output I've already listed here. Only slice 0 is mirrored on this machine? Or is it the entire disk (all slices)?

you would have to post the output of "metastat". you get the definition of every mirror in your maschine without any option..... but as far as i can see now at your df -k output the "/" and "/opt" is based on metadevices.....

Here's the output of metastat d2 - looks like d2 is a mirror of slice 0 and d8 is a mirror of slice 6. Am I correct?


root@lycincs2:/# metastat d2
d2: Mirror
Submirror 0: d0
State: Okay
Submirror 1: d1
State: Okay
Pass: 1
Read option: roundrobin (default)
Write option: parallel (default)

d0: Submirror of d2
State: Okay

Stripe 0:

c1t0d0s0 0 No Okay


d1: Submirror of d2
State: Okay
Size: 4111104 blocks
Stripe 0:

c1t1d0s0 0 No Okay

And metastat d8 -

root@lycincs2:/# metastat d8
d8: Mirror
Submirror 0: d6
State: Okay
Submirror 1: d7
State: Okay
Pass: 1
Read option: roundrobin (default)

I've been working with HP-UX for a long time. I have never seen anything like that. Here is the bdf output from two different HP-UX systems:

Code:
Filesystem          kbytes    used   avail %used Mounted on
/dev/vg00/lvol3     204800  106448   97640   52% /
/dev/vg00/lvol1     298928   61480  207552   23% /stand
/dev/vg00/lvol8    4710400 1324552 3362776   28% /var
/dev/vg00/lvol7    3145728 1694752 1439696   54% /usr
/dev/vg00/lvol6    1048576  402376  641168   39% /tmp
/dev/vg00/lvol5    8388608 5357120 3007912   64% /opt
/dev/vg00/lvol4    6291456 2420010 3630283   40% /export1

Filesystem          kbytes    used   avail %used Mounted on
/dev/vg00/lvol3     204800   90216  113704   44% /
/dev/vg00/lvol1     298928   49144  219888   18% /stand
/dev/vg00/lvol8    4710400  557232 4121312   12% /var
/dev/vg00/lvol7    2916352 1259240 1644832   43% /usr
/dev/vg00/lvol4     204800   25128  178464   12% /tmp
/dev/vg00/lvol6    1720320 1380704  337000   80% /opt

Can you tell me anything at all about the physical disks involved? One of the system has MirrorDisk/UX installed; and on that system, vg00 is mirrored. Which system? The HP-UX /dev/vg00/lvol1 and the SunOS /dev/md/dsk/d2 are actually rather close in concept. In both cases you need another command to trace back to the physical disk. Now looking at the SunOS "df -k" output...
Code:
Filesystem            kbytes    used   avail capacity  Mounted on
/dev/md/dsk/d0        493688   50002  394318    12%    /
/dev/md/dsk/d4       1133429  584244  492514    55%    /usr
/proc                      0       0       0     0%    /proc
fd                         0       0       0     0%    /dev/fd
mnttab                     0       0       0     0%    /etc/mnttab
/dev/md/dsk/d5       1527116  670262  795770    46%    /var
swap                 2903888      40 2903848     1%    /var/run
swap                 2903912      64 2903848     1%    /tmp
/dev/md/dsk/d8       17403836 16214482 1015316    95%    /worldscope
/dev/md/dsk/d7       2622176 1864275  705458    73%    /export
/dev/md/dsk/d6        736904    3430  674522     1%    /opt

the main difference that strikes me is "capacity" verses "%used".

I'm not sure I understood all your questions for me from the last reply. I do agree that that df -k and bdf are very simular, I was just confused by the mirroring and why some of the system type info is list the way it is. Could you explain one last point for me...
I see that /proc, fd, mnttab & swap are listed in the df -k. And I can see that /proc, fd & mnttab don't actually have any space allocated to them. I know that mnttab is used by the system to keep track of mount points. What is the purpose of /proc & fd? And why does swap have two listings and mounted at /var/run & /tmp?
thanks guys!!

/tmp and /var/run are swap-based filesystems. Anything in them will disappear at reboot time. They are like "memory-disk" filesystems, except that they use vitrual memory rather than physical memory. Putting stuff in /tmp or /var/run consumes some swap space. The proc, fd, and mnttab are psuedo filesystem they don't count as disk space at all. /proc is all of the processes. ps runs by looking at it. /dev/fd lets you treat your file descriptors as if they were files. mnttab is a file system that exists only for /etc/mnttab... not my favorite idea, but /etc/mnttab is *alway* in sync with the kernel table.
