A "Linux systems specialist", did claim my previous business card and did so from 2001 to May 2013. Then it said "Senior System Administrator" in another company, Stonesoft, which is part of McAfee/Intel Security. And now, since February 2015, it seems to have "Information Security Analyst at Intel Security" printed in it. Phew, all this title massage is getting heavy!

My heart also has a place for FreeBSD.

comment Using lynx or wget in cron to call a php script?
I don't know why I'm using -dump (or -source) options, must be some old habit. Gotta try what happens without them ... one way to get notified if something went wrong would be to configure your cron script to return some string like "SUCCESS", and then grep for it. If that string is missing, then send out an e-mail. For example, 'lynx -dump example.com/cron/scriptA.php | grep "SUCCESS" && echo "OK" || ( echo "Not OK" | mail -s 'Something went wrong' swatteam@example.com' )

comment disk hangs during active I / O
How is rsync slow? With the latest (1-3 years old...) 3.x generation it's actually quite fast. Third generation removed the old "I'm gonna generate the whole file list before transferring anything" annoyance, and as a bonus if transfer gets interrupted with rsync, it can nicely continue from the point it was interrupted and it's not gonna copy everything again, like your copy command would. I'm using rsync for transferring 4.5 terabytes (around 35 millions files) and it works just fine. :)

comment MySQL says replication is fine but data is not copied
One more obvious question: are the MySQL file/directory permissions OK in the slave? Yes, MySQL should complain loudly if something's wrong, but MySQL sure has fulfilled itself with full of small gotchas. Other than that, I'm running out of ideas.

comment MySQL says replication is fine but data is not copied
This has to be the most obvious question ever, but has bitten me once: is there enough free disk space on the slave server? Many moons ago I spent the whole evening pondering a similar problem, just to find later that df -h returned 100% for the MySQL data partition ...

I presume you restarted MySQL? And the line in /etc/mysql/my.cnf says "table_cache = 512"?

comment Do read operations work on ext3 filesystems when the filesystem is full?
@pankaj: It will read the data until the hard drive dies. Filesystem getting full does not harm read operations in any way or in any time period, but the write operations will fail. But, please clarify your question a lot if this does not answer you.

comment fork: Resource temporarily unavailable running JVM
Maybe the kernel itself runs out of filehandles. What does "sysctl fs.file-nr" and "sysctl fs.file-max" return?

"Only"? Do you realize that with useradd and userdel someone could replace your root account and that's the end of story?
