Hard Drive Monitor

[rbautch]

Here is a script that detects errors on your Tivo hard drive(s) by:
1. Scanning your kernel log looking for errors indicative of hard drive failure.
2. Running smartctl and checking for S.M.A.R.T. status of "failed".
3. Running extended offline drive checks using smartctl.
4. Comparing the temperature of your hard drive(s) to a user-defined threshold.
5. Comparing the number of reallocated sectors to manufacturer thresholds.
If an error is found or a value exceeds a threshold, it writes it to a log, and sends it to your Tivo UI as a message.

Usage:
Run it as a shell script from bash without arguments. If the script detects a cron installation, it will automatically append your crontab to run drivemonitor.sh every night.

Note:
Features 3,4, and 5 above require a newer version of smartctl than the one that ships with stock Tivos. Jamie was good enough to compile one and attach it to Post #5 below. I suggest replacing your existing smartctl in /bin with this one.

Tested on 6.2 Dtivo, but should work on all platforms.

cool tool. I'm running 6.2a on a DSR7000, single seagate 300GB drive, here's the output - - look like what you'd expect?

root@lvrmtivo:/var> drivemonitor.sh
No hard drive errors were found in your kernel log.
Device open failed: No such device or address
Your primary drive hda S.M.A.R.T. satus is: PASSED
Your secondary drive hdb S.M.A.R.T. satus is: FAILED
Your secondary drive hdb S.M.A.R.T. satus is: FAILED
root@lvrmtivo:/var>

Not quite. It erroneously thinks you have a secondary drive (hdb). What version of smartctl do you have? (usually in /bin)

version 1.2

That's pretty ancient. I've been using 5.32 for quite a while -- looks like I built it back in 2005.

smartctl -H /dev/hdX is useful with this version, as well as smartctl -t short /dev/hdX. smartctl -a /dev/hdX displays a ton of info that you might find useful, typically including the temperature of the drive, the number of remapped sectors, etc.

thanks, now I'm up to date with a version from this century

Thanks for the updated smartctl, Jamie. I'll plan to make some updates to the script to take advantage of those features. I just updated the script to be backwards compatible with older versions of smartctl too.

Just checked, Alphawolfs All-In-One file has 5.32 version of smartctl included.

Cool...

How do I make an CRON entry to run this say once a week just before the logs get wiped. I put the file in /enhancements

Set the day of the week and execution time for drivemonitor before you clear your logs

# cron settings
# * * * * * command to be executed
# - - - - -
# | | | | |
# | | | | +----- day of week (1 - 7) (monday = 1)
# | | | +------- month (1 - 12)
# | | +--------- day of month (1 - 31)
# | +----------- hour (0 - 23)
# +------------- min (0 - 59)
# time is based on utc no time zone offset calculated

* * * * * ./drivemonitor.sh; echo "Ran DriveMonitor on `date`" >> /var/log/crontab.log

FYI, the info module of TivoWebPlus uses "smartctl -c" to check SMART status, which is compatible only with older versions of smartctl. Editing TivoWebPlus/info.itcl to change the argument from -c to -H fixes this. Not a huge deal, but I'll make the TWP developers aware of it.

Yes, I think I sent it to him for inclusion (link).

The issue may be that /bin is on the path before the hacks bin directory, for some people, so they get the old version tivo ships if they don't specify the full path.

Wow, something in the 9.3 update messed up my Joe command. This is what I get when I type root for my CRON config. I looked in /tivo-bin and there is no /etc there so the error appears to be correct. Thoughts how to fix this?

FamRoom-bash# root
Couldn't open '/tivo-bin/etc/joerc'

joe looks for joerc in two places. First it looks for "/.joerc", then it looks for "/tivo-bin/etc/joerc/".

If you used an automated script to install your hacks then most likely it's using "/.joerc", which you simply need to copy over from your previous install.
