Re: [lustre-discuss] lshowmount equivalent?

2015-12-15 Thread Thomas Stibor 

I have pushed an updated version of lshowmount where warnings and mostly
strcat -> strncat, sprintf -> snprintf are fixed, as well as other issues.

This is a very cool and useful tool which I was not aware before.
I did tested parameter "-l -v -e" combinations on MDT/MGS and OSS,
and it works so far.

Cheers
 Thomas


I did some testing with the "old" lshowmount tool and found it very usefu

That means someone who knows how this tool is supposed to work needs to
fix any compile problems, test it a bit manually, and make a short test in
conf-sanity.sh that verifies it continues to work as expected in the
future.

I don't mind to carry this in the Lustre tree, so that it can be updated
as things change (e.g. /proc to /sys conversion and such), but it needs at
minimum a new test so that it doesn't silently break in the future.

If it makes more sense for it to be a separate tool outside the lustre

Hi,

lshowmount is actually very useful for knowing which nodes are connecting
to the Lustre. I use it in one of my scripts to ensure clients and OSSs
already umounted.

Andreas, hope that we can bring it back :).

Regards,
Cuong

Andreas,

I wasn't familiar with that tool, but now having tried it... I find it
quick and easy and helpful and would love to have it in future releases.

Is this a tool that you are using?  IIRC, there wasn't a particular reason
that it was removed, except that when we asked LLNL (the authors) they
said they were no longer using it, and we couldn't find anyone that was
using it so it was removed in commit b5a7260ae8f along with a bunch of
