Hey Folks,
Recently I had a problem where a *nix system NFS was hung on a server
which had "gone away," but the client hadn't umounted the filesystem.
Later, this caused a script in cron to fail, in that a df command inside
the script never completed, and instead it "hung," causing the script
to hang awaiting a completion of df, which it never got.
999 times out of 1000 this has not failed, but when that one time
comes along, all hell breaks loose.
I'm not sure what approach to take to alleviate the cascading failure.
I'd prefer to just abort the df, log the error, and complete the rest
of the script. Short of totally re-writing the script (it's not mine,
to begin with), I would like to modify it. It's a simple system command
being used:
system ("/usr/sbin/df -kl");
Ideas?
Thanks,
deb
