How to check free space for a metadevice in a diskset

UNIX Solaris

Anyone know then command to check the unallocated disk space for a metadevice in a disk set? like:

/dev/md/data/dsk/d830

Something similar to veritas command below is what I'm looking for:

vxassist maxgrow <volume>

---------- Post updated at 12:34 PM ---------- Previous update was at 12:17 PM ----------

metarecover -v -n -s data d801 -p

that did the trick.

---------- Post updated at 01:08 PM ---------- Previous update was at 12:34 PM ----------

This produced output like this:

The following extent headers were found on data/d801.
Name Seq# Type Offset Length

       data/d950     0   ALLOC           3179283327             10485761
       data/d955     0   ALLOC           3168797535             10485761
            NONE     0     END           3302785023                    1
            NONE     0    FREE           3189769088            113015935
            NONE     0    FREE           3179283296                   31
            NONE     0    FREE           3168797504                   31

Anyone know an easy to convert this readouts to GB ?

I did this but it seems a little off:

bash-3.00# echo "(113015935*512)/1073741824" | bc
53

53Gb available?

Take this with a grain of salt - I'm a little outside my area of expertise here :slight_smile:
I would say you could check you answer by adding up the two extents listed as 'ALLOC' ie (10485761+10485761)*512/(1024^3) and see if that + 53 is the total size f the disk (minus some overhead and 62 blocks for the other 'free' spaces)
