| Jun 16, 2016 at 9:41 | comment | added | Ronny Nilsson | Having a MySQL db (or other db) on a SD card is risk. As an alternative, send the data over network to a remote db. | |
| Jun 15, 2016 at 12:59 | comment | added | goldilocks | Also: The conclusion that it is SD card failure seems like one that is simply convenient rather than one that much effort has been made to verify -- convenient in the sense that you don't have to make any further effort to diagnose the problem if you are satisfied with, "Well, the ACT light isn't blinking, I guess it is SD card failure...". Using a watchdog timer will throw better light on whether or not the entire system is really failing, or whether it has simply stopped doing what you want and gone offline. | |

| Jun 15, 2016 at 12:49 | comment | added | goldilocks | I'll strongly disagree with Milliways WRT "there is no advantage in using Class 10 cards" in that while the top speed of the Pi's SD card interface is slower than the top speed of a class 10 card, pretty much all of the cards reported as achieving the maximum write speed (20-25 MB/s) on the Pi are class 10 or better. I'll concur with him about the usefulness of a watchdog timer here though. | |
| Jun 15, 2016 at 12:49 | comment | added | goldilocks | Normative syslog implementations, including rsyslog, are interoperable with journald, and on stock Raspbian this is enabled by default and configured such that a copy of all messages should be present in /var/log/syslog -- so either you've disabled this, which is probably pointless and unwise, or you are not running stock Raspbian (in which case indicating what OS you are using is not super relevant, but at least worth mentioning). The advantage to this is that /var/log/syslog is a normal text file which is easy to examine if you remove the card after a crash (although not necessary). | |
| Jun 15, 2016 at 12:42 | comment | added | Quentin Geissmann | @Milliways. Thanks, I think this is a good idea, and I am working on persistence of my software after reboot, I will investigate how to make a watchdog. | |
| Jun 15, 2016 at 12:39 | comment | added | Quentin Geissmann | @goldilocks There is no /var/log/syslog in my system. My understanding is that it is centralised to systemd. I meant I looked at the system log, using journalctl after crash, to investigate what happened before. | |
| Jun 15, 2016 at 12:34 | comment | added | Milliways | SD Card manufacturers do not support using them for an OS so this is not entirely unexpected. You could consider retiring cards which do not perform and/or try different brands. NOTE that there is no advantage in using Class10 cards on a Pi - even though they are better at HD video (they are optimised for high speed sequential writing). More practically you should try implementing the watchdog timer (included on the SOC) to detect failure and perform a graceful restart - this is the normal engineering approach because ANY system can fail for inexplicable reasons. | |
| Jun 15, 2016 at 11:49 | comment | added | goldilocks | "journalctl does not show anything at all before it happens" is a little like saying "My car was fine before it drove off the cliff". That's a little snarky and of course for some problems -- particularly I/O failure, which is what you've said seems a likely candidate -- it might. However: Have you tried examining /var/log/syslog for clues after rebooting? Have you tried plugging in a screen and keyboard before rebooting to see if it is possible to do some diagnostics that way? | |
