<div dir="ltr">If 48 hours are required for this, maybe we can offer backup solution which will work as before.

<div class="gmail_msg">Why do you need 48 hours for that?</div>
<div class="gmail_msg"> </div>
<div class="gmail_msg">I'm submitting very many cron jobs the day to deliver much stuff and services to a lot of users in dewiki and other wikis. An outage window of 48 hours (!) is simply not possible.</div>
<div class="gmail_msg">Please suggest a solution how I can work on during the outage window or at least a crontab that can handle the data and files on tools.taxonbot. You maybe can install a NFS redundancy for at least that time.</div>

<div class="gmail_msg">As the next step in our storage redundancy and reliability efforts for Labs, we have a significant migration coming up on 11/2 starting 08:00 PST(15:00 UTC) involving the tools NFS share. The maintenance window can be up to 48h long, and will affect most running tools. At the end of the migration, everything (except transient jobs) should ideally be working the same way as they were before the migration, but better.</div>
<div class="gmail_msg"> </div>
<div class="gmail_msg">Here's what to expect during the maintenance window:</div>
<div class="gmail_msg"> </div>
<div class="gmail_msg">* The tools NFS share (/data/project and /home) will be read-only for the duration of the maintenance, so no new data or logs will get written to it.</div>
<div class="gmail_msg">* New jobs cannot be submitted for the whole maintenance window - this means submitting jobs through cron or tools-mail will not function, although tools-mail can continue to send emails. </div>
<div class="gmail_msg">* Current jobs might keep running, but won't get rescheduled if they die. If they do not die and aren't writing to NFS they should be fine. </div>
<div class="gmail_msg">* All exec nodes will get depooled, rebooted and repooled and jobs that don't get rescheduled automatically will have died and need manual restarts.</div>
<div class="gmail_msg"> </div>
<div class="gmail_msg">Do let us know if you have any questions or concerns on the lists or on #wikimedia-labs.</div>
