[SOLVED] Garmin troubles

Update: solved after my watch received software update 7.80. Scroll at the bottom for details.

I have never been a watch person. Have not worn one in a looong time and never really got interested in one even when the smart watch hype started mounting.

Two months ago a was gifted a cheap knock-off step tracker and I suddenly realized that I was interested in having that kind of data (steps, sleep) tracked. The cheap tracker died after a few weeks, so I started my hunt. I like running (I try to run 5K, 3 times a week) so I thought maybe I should upgrade from a simple fitness tracker to a watch that I could use for running.

After a little of bit of searching I settled of the Garmin Forerunner 235. It checked all my requirements:

  1. physical buttons
  2. long battery life (at least a few days, I managed 6-7 days on a single charge)
  3. some smart features like notifications, calendar
  4. cardio sensor, and an accurate one at that
  5. GPS
  6. price in the 200€ 
At the beginning of May 2018 I got one from Amazon Warehouse in new condition, for 170€ and I immediately loved it. I particularly liked the alert to get up and move and the motivation to reach the daily step target. Receiving notifications from the phone to the watch was incredibly useful (I don't receive a lot of them, I guess if I got too many it could be annoying).

I checked cardio senso accuracy against a Polar chest strap and they pretty much matched each other. It was all rainbows and unicorns for two full weeks, until one day the watch started losing the time: all of sudden the hours would be wrong (like 2 or 3 hours wrong, not just minutes). Then after a few days it also started resetting (crash, then reboot...crash then reboot in a loop) continuously. I tried the usual turn-it-off-and-on-again trick, then reset procedure and finally clear user data procedure. When all that failed to work I returned the watch. Then I bought another brand-new Forerunner 235, hoping it was just a defective unit.

Unfortunately it had the same problem: as soon as it paired with the phone it would run a sync cycle, then crash and reboot. In an endless loop. I was dismayed.

So I set on a troubleshooting course that I decided to document here. As of now the issue has not been fixed yet, but I was able to establish a few facts:
  1. the problem does not seem to happen on my wife phone (an entry level Samsung on some Android 4.4.4 , whereas I have a Samsung S7, fully updated)
  2. updating the Garmin Connect app does not fix the issue, I'm on 4.7 atm
  3. updating the watch firmware to the 7.73 beta does not solve the problem
  4. resetting the watch and performing a number of procedures suggested by Garmin support (like removing all *.FIT files) did not improve the situation
  5. reinstalling the Garmin Connect app and/or removing then adding the watch again does not help
  6. suspecting it might be a smart notification problem I disabled them, but the watch kept resetting
  7. the problem is definitely related to some interaction between the Watch and the Garmin Connect app. If I turn off bluetooth (on the phone or the watch) the watch works perfectly and does not crash
I am now using the watch paired to my wife's phone but that's less than ideal.

Update June 4th 2018

A Garmin support person told me that they are aware of some problems with Samsung phones and a fix should be ready "in a few weeks". I find hard to believe there are problems with probably the largest Android manufacturer and, if the few weeks promise does not materialize, I might not be able to return the watch to Amazon.

Update June 16th 2018

Last week Garmin reached out via twitter. After gathering further information about phone and watch they have opened a technical case, so hopefully this will get resolved.

Update June 18th 2018

Samsung released Android Oreo for the S7. I just installed the update, but the problem with the Forerunner persists.

I'll update the post as the situation develops.

Update Jul 19th 2018

Yesterday evening my watch notified me of an available update. I checked the Garmin website and the update mentions fixing bluetooth connection and sync with the mobile app: looks just like my problem. I went ahead updated the watch and then connected it to my S7: so far it's been running 12h without issues. Thanks Garmin!

From 0 to ZFS replication in 5m with syncoid

The ZFS filesystem has many features that once you try them you can never go back. One of the lesser known is probably the support for replicating a zfs filesystem by sending the changes over the network with zfs send/receive.
Technically the filesystem changes don't even need to be sent over a network: you could as well dump them on a removable disk, then receive  from the same removable disk.

Indexing Apache access logs with ELK (Elasticsearch+Logstash+Kibana)

Who said that grepping Apache logs has to be boring?

The truth is that, as Enteprise applications move to the browser too, Apache access logs are a gold mine, it does not matter what your role is: developer, support or sysadmin. If you are not mining them you are most likely missing out a ton of information and, probably, making the wrong decisions.
ELK (Elasticsearch, Logstash, Kibana) is a terrific, Open Source stack for visually analyzing Apache (or nginx) logs (but also any other timestamped data).

Mirth: recover space when mirthdb grows out of control

I was recently asked to recover a mirth instance whose embedded database had grown to fill all available space so this is just a note-to-self kind of post.
Btw: the recovery, depending on db size and disk speed, is going to take long.

The problem A 1.8 Mirth Connect instance was started, then forgotten (well neglected, actually). The user also forgot to setup pruning so the messages filled the embedded Derby database until it grew to fill all the available space on the disk. The SO is linux.

The solution First of all: free some disk space so that the database can be started in embedded mode from the cli. You can also copy the whole mirth install to another server if you cannot free space. Depending on db size you will need a corresponding amount of space: in my case a 5GB db required around 2GB to start, process logs and then store the temp files during shrinking.

Then open a shell as the user that mirth runs as (you're not running it as root, are you?) and cd into the mirth home. …
