bdfmegs ver 5.3

[Bill Hassell]

Hi all. The latest bdfmegs is now available (attached) and has a much needed option to change the divisor between 1024 and 1000. The default is now 1000 (was 1024) but a one line change can be used to change the behavior back to 1024. Additionally, the -d option will toggle the default divisor to the opposite value.

Here's the -h (help) option:

Usage: bdfmegs [ -cdghlNPpqstuVv ] [ ]
where:
-c # = Sort on column #
-d = Toggle divisor (1000 or 1024, current=1000)
-g = show gigabytes, otherwise megabytes
-h = Usage (return code=0, Usage to stdout)
-l = local (no NFS)
-N = skip one or more volume groups
Repeat -N or use commas: -N vg10,vg24
-p ## = highlight % -ge ##
-P ## = show only % -ge ##
-q = suppress header line and no char enhancements
-s = summarize total, used and available
-t = specifc filesystem: (hfs vxfs nfs cdfs cifs autofs DevFS)
-u = usage (return code=0, Usage to stdout)
-v = verbose (type, version, largefiles)
(version info read permission for mountpoint)
-V = select one or more volume groups
Repeat -V or use commas: -V vg00,vg01

File(s) or dirpath(s) may be specified to reduce the output of bdfmegs:

bdfmegs -vg /usr/contrib/bin /var/tmp

If bdfmegs is run as bdfgigs (ie, a link), then -g is default.

thanks Bill,
i had downloaded it and will try with one of my test unix system.

i think in this update -V option is very usefull,

thanks again.. :)

[Arturo Galbiati]

Thanks Bill.
This is not only a good tool, but a good example of shell programming as well.

Thank you Bill, I tried previous version and it was good. Now I will try this.

Hi,

I tried -d switch, could you please look at the output in my 11i v1 HP-UX server:

# ./bdfmegs -vd /usr/contrib/bin /var/tmp
File-System Mbytes Used Avail %Used Type Vr Lrg Mounted on
/dev/vg00/lvol8 2048 1414 628 69% vxfs 4 yes /usr
/dev/vg00/lvol9 2048 833 1205 41% vxfs 4 yes /var

# ./bdfmegs -v /usr/contrib/bin /var/tmp
File-System Mbytes Used Avail %Used Type Vr Lrg Mounted on
/dev/vg00/lvol8 2097 1448 643 69% vxfs 4 yes /usr
/dev/vg00/lvol9 2097 853 1234 41% vxfs 4 yes /var

-different MB(s) ,so I admit that I could not quite catch the reason for this, can you explain why added this workaround ?

In the first output, using the '-d' switch, it is forcing the use of 1024 as the divisor for figuring MB and GB. Your output shows the the LVOLs are '2048 MB' (2 GB) which is 2,097,152 KB / 1024.

The 2nd output is using 1000 as the divisor. Thus it is showing 2,097,152 / 1000 = 2,097 MB for your LVOLs.

Sorry Hakki, I messed up your points - you deserve 8 for asking a common question. Patrick beat me to the answer. If you compare bdf to bdfmegs (ver 5.3), the numbers will match. The 1024 option is not that useful

[Hakki Aydin Ucar]

I got the answer. it is a matter of resolution for me. Thanks for the replies.

No matter point I received.

Bill, I have been using bdfmegs for some time now, and find it extremely useful. At times I have multiple snapshot filesystems mounted, which truly are only built at 10% of the actualy filesystem. However, in bdfmegs they appear as the identical size of the original (rather than the 10%). All of my snap lv's are names as such (/dev/vgtrn/lvtprepip_snap) always mounted to a /backups mountpoint. Is there any way that these could be excluded from the TOTALS calculation that bdfmegs does so well? Thanks in advance!

[Fabian Briseño]

Hello Bill.
Thanks a lot for the script.


Have a great day everybody

[Bill Hassell]

> Andy: snap exclusion...

This will be a bit tricky. I can add an option that skips a pattern in the mount point or the source lvol but then it won't be shown at all. Snapshot volumes are not real filesystems but are actually a composite of the unchanged blocks in the original filesystem plus an image of the changed blocks. It only has meaning when it is mounted and will match the size of the snapped volume rather than the raw disk space.

I will enhance bdfmegs to identify snap volumes and figure out some way to represent usage. mount -p reports snapsize but this isn't relevant for filesystems that bdf is representing so I will probably exclude snaps in sum totals.

Dear Bill,

Really very nice work, appreciated your efforts.

Asif Sharif

[AndyMueller]

Bill,

I would be totally fine, if the snapshot volumes could be excluded from bdfmegs entirely. There is a great little program called snapbdf that I use to collect and capture the snapshot data for. Thank you you so much, i am amazed that you would edit your script for just one person! THANK YOU so MUCH!

Andy

Absolutely fantastic and most useful! Thank you!

Hi,

Iam very new to HP UX..

How do i install the attached script in HP UX.

Thanks
