Most of the probe down because of USB Stick read-only
Hi, I just realised that most of my Ambassador Probes are offline probably caused by USB stick that turned into read-only mode. A couple of guys that I contacted and I give them instruction to reformat the USB stick said that the USBs are read only. I already told them to try to change the USB sticks, but looks like none are voluntarily (buy a new USB/use their USB stick) to change the USB sticks. Any idea how to revive the dead probe? Thank you Budiwijaya
Hi , I've spent significant number of hours trying to do that. No luck. I did ended up with Verbatim stick. There's no way to get it out of RO mode. Then I just went to the store and bought 8 Gig USB 2.0 Kingston. Works like a charm :) Thank you Dušan Vučković mag.sci.EE, MCP| Faculty of Electronic Engineering |Head of IT +381 18 529373 +381 69 1583000 +381 18 588117 | Aleksandra Medvedeva 14, Niš 18000, Serbia -----Original Message----- From: RIPE-Atlas-Ambassadors [mailto:ripe-atlas-ambassadors-bounces@ripe.net] On Behalf Of Budiwijaya Sent: 28. септембар 2016. 14:18 To: RIPE-Atlas-Ambassadors@ripe.net Subject: [RIPE Atlas Ambassadors] Most of the probe down because of USB Stick read-only Hi, I just realised that most of my Ambassador Probes are offline probably caused by USB stick that turned into read-only mode.

Finally! Same here.... Months into the project, I wish I have hit the 50 or even 100 probes by now. Yet, I'm stuck with faulty probes here and there and I am asking too much from non-technical and geographically dispersed hosts to literally repair their uninvited out-of-my-reach pets. Buying a new USB memory is a whole new story. Guys, please either fix the software or do logging with probe's internal memory, or whatever. This is becoming a huge drawback. Regards, M.

In other words, this may be caused by the USB power source. Have you tried using a dedicated mains socket to USB converter for the units which are showing problems? Nick
I've tried with power adapter for 1 router that was not working. Regards Durga Prasad Datasoft Comnet Pvt. Ltd.

This, I cannot guarantee the probes will be connected to a stable power source. My probe, connected to a mikrotik usb port. Still working fine up to now. As said by Tajbakhsh, buying a new USB sticks is a whole new problem for them. Thank you Budiwijaya

you need to fix your power supply problems to the probes, then Like anything else, if a probe doesn't have reliable power, it is unlikely to work properly. Nick
Hi Nick, The probe that has a problem are not in my network, that's why I cannot guarantee the power source stability. Thank you Budiwijaya On Fri, Sep 30, 2016 at 8:09 PM, Nick Hilliard <nick@netability.ie> wrote:

There are two normal failure scenarios: either the file system on the USB drive becomes corrupt, or the USB drive stops working. There are instructions for dealing with both cases on the ripe web site, which are (simplified): corrupt filesystem: power down probe, remove USB drive, power up probe, wait 10 minutes, insert USB drive, wait 1 hour corrupt usb drive: power down probe,remove USB key and insert clean 4G+ USB key, power up probe, wait 1 hour The v3 probes seem to be less tolerant to power problems than those of the v1 and v2 probes. Nick
Yes, already told that to all the host that host probe that distributed by me. Getting feedback from one and two of them that the USB is read-only. I just tested one of the dead probe, can be brought live by replacing the USB disk. Also realized that my own probe are using SanDisk and the dead probe are using Verbatim. Looking at the Philip report, looks like the Verbatim are more prone to error. Further analysis, can we as ambassador find out which one are probe that using Verbatim and which one are Sandisk?

dunno, maybe the RIPE NCC people would be able to answer that? Nick
I don’t know that this problem is exclusive to power, and I think you’re on to something with the version of the USB flash. I have had a significant amount of my probes (all from the same batch) all stop working due to USB flash drives failing, and all of them have reliable power in stable environments. I ended up replacing the USB drives in the ones I could get access to or had the host replace the USB sticks which has resolved the issue in every case. FWIW, I replaced them with Sandisk USB drives. nb On Sat, Oct 1, 2016 at 8:28 AM, Nick Hilliard <nick@netability.ie> wrote:

Hi, The best (visual) description of this is in Philip's article: https://labs.ripe.net/Members/philip_homburg/outsmall.png/@@images/image It clearly shows our switch to Verbatims at around probe 22000. We could be more specific if there's a need. Also, the newest batch of probes (from 28900 or so) uses a third kind of USB stick (coincidentally, Philips ;-) Regards, Robert
Dear Nick, Yes, I have. Actually the usual way to run them, here in my country, is via dedicated adapter as we have discussed before. Free USB port on routers, etc is a rare option here. I have even the hosts put them on surge protectors and UPS's if handy. Did that myself as well. Yet, dead probes come up every few weeks. Thanks for sharing the useful links, (the failure rate on that graph is a disaster) that still brings up two more issues: 1- Though that's an insight, what good can that do for the problem of physically unreachable probes (including those with distant non-tech hosts)? 2- If there's an ongoing research about such an important issue, why didn't we ambassadors get a serious notification on this list, for God's sake? We could have been informing people in advance. Just saying... I have distributed both Verbatim & SanDisk probes and 4/5 of my batch is down already. I think that is on the Atlas Monitors as well, yet the atlas servers feed me with single "your probe #xyx is down" e-mails. Still here to do more, I am also really disappointed with the energy and time I spent for dead probes, let alone the thousands of kilometers of land travel to spread them. Soon we will probably be replacing every 3rd gen. probe on the planet. Am I the only one panicking? Bringing the white "black box" we gave people up every now and then, and expecting yet another favor, won't help us in the long run. They have trusted us and we gave them some cheap toys. If the project wants to reach every corner, not just healthy and wealthy spots, then the probes should be as stable and standalone as possible. Yes, failures happen, but the right piece of hardware for this project, I believe, is what works with the minimum failure rate as long as the power grid is on and the router is connected, and the host forgets it's even there. End of story. Yours, M. Tajbakhsh Nick Hilliard wrote:
