Recently a good friend be-gifted me Banana PI M3<\/a> for my birthday. I decided to turn it into a NAS. Granted it is no Synology NAS <\/a>but it gets the job done and openmediavault <\/a>is a wonderful software suite to use on it. I thought to myself, “It would be nice to get a notification if there are any I\/O errors via dmesg on my homemade NAS. So I whipped up a simple solution:<\/p>\n

vim \/bin\/ioerrorcontact<\/p>\n

#!\/bin\/bash<\/p>\n

if dmesg | fgrep ‘I\/O error’ &> \/dev\/null;
\nthen
\ncurl http:\/\/textbelt.com\/text -d number=MyPhoneNumber -d message=”I\/O Error on your NAS” &> \/dev\/null;
\nfi<\/p>\n

crontab -e<\/p>\n

0 * * * *\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 bash \/bin\/ioerrorcontact<\/p>\n

This is just a quick and simple hack but it’s peace of mind knowing that I have something in place to notify me if my simple NAS is having any issues, especially since I do not have RAID 1 configured on it. RAID 1 via BananaPi or really any other Pi devices at this point isn’t really that great because you would have the split one SATA channel\/bandwidth to be able to get it to work. I also strongly recommend that if you’re going to build a low powered NAS device using a Pi device, to use the BananaPi because it has gigabit Ethernet. Other than that, if you have the money to shell out and want a better solution, I recommend Synology NAS products.<\/p>\n
