Hello,
Apologies for the scattergun approach, but I am trying to make sure that I don't inadvertently cause problems for anyone who might still be using the older Analytics Clients, namely stat100[4-7], as they are to be decommissioned shortly.
My plan is to merge this
patch tomorrow, June 5th at approximately 10:00 UTC, which
will disable user login to stat100[4-7].
If you still need to move files from these servers to a different stat server, or to HDFS, please refer to the guidelines here:
I plan to keep these servers running in this 'insetup' mode for about a week, just in case there is still something useful on them, before finally decommissioning them.
If this schedule is inconvenient for you, or you have any other
concerns about the work, please don't hesitate to reply or to
contact the Data Platform SRE team. You can use
#data-platforms-sre on Slack, or #wikimedia-data-platform on IRC,
or ping me direct.
Kind regards,
Ben
I have not been able to make this change today, so I will schedule it for next week instead.
Kind regards,
Ben

Please ensure that you have copied any important files to different stat servers or to HDFS before then.
Feel free do get in touch with us at if you have any concerns about this schedule.

Hello,
We need to plan to decommission several of the analytics clients, also referred to as the stats servers, since they have reached their end of service date. The servers in question are:
If you actively use these servers, please consider moving your work to alternative stat servers (namely, stat10[08-11]) as soon as reasonably possible.
Similarly, should you have personal files in your home directory on any of these servers that you would like to retain, now would be a good time to consider moving them to a different server, or moving them to your HDFS home directory.
There are some guides available on syncing files between stats servers and also using the hdfs CLI to manage files, which may help you to clean up the necessary files.
We would like to be able to decommission these servers three weeks' from today, which is on Tuesday May 28th. Please do feel free to get back to us if you feel that this timescale will not allow sufficient time for you to migrate your work to alternative servers, or if you have any other concerns about this plan.
Kind regards,
Ben
