Today we have conducted yet another user directory migration, this time done as an emergency. We managed to get our new storage system for userdata up and running (separate from all other systems) with SSD-based storage, and took the decision to migrate everything directly instead of scheduling a maintenance, due to the mail problems we have had. The temporary storage we had were running on old HDD-based storage and could not keep up with the iops from both mail, virtual machines and user directories, which is why you have been seeing connection and mail delivery issues for some time now.
We hope that this new solution can be permanent and serve all users well, with increased uptime and speeds.
New user directory prefix is /ludd/users, we decided to make this move to make
any future moves technology agnostic, so that we dont have to change userdir
paths.

Tomorrow (24th of Oct, 2019) we will start migrating user directories from AFS to GlusterFS.
This is being done for multiple reasons, including incompatiblity with our thin client cluster, performance, manageability, to name a few.
The main noticable change will be the home directory prefix going from
/afs/ludd.ltu.se/users to /gfs/users. Please make sure to update any scripts
that use the full path as the old one will go read only when we migrate.
Some mails might take a bit longer to arrive when your account is being migrated, this is due to us pausing deliveries to ensure consistent state of mail directories.
Please report any issues you might encounter that could be related to the migration to the administrators e.g. via telegram.

On the evening of 23rd of June, ALL LUDD services will be shut down for power maintenance as well as maintenance of OpenStack and member services. This includes all LUDD services, LUDD DUSTcloud services, LUDD DUST HPC services, as well as virtual and physical LCNet offerings.
Mail services will also be down, so the primary point of contact with LUDD
administrators will be via #ludd @ irc.freenode.net or LUDD:s Telegram

are interested to help or curious about what will be done, contact

We reserve for all services to be down until the 1st of July, but hopefully they will be restored as soon as possible.

On the 25th of March, all systems and networks on LUDD and LCnet will be down during the whole day. This downtime might extend to the 26th as well.
Systems will be shut down on the 24th at 23:00. (LCNet users, please shut down beforehand, as we will only cut the power to the racks).
LUDD DUSTcloud services will also be down during this time, including all users machines.
The reason is due to electrical work in the datacenter.

We assume you've heard about EU:s new GDPR initiative. The rules state that we have to give you clear informtaion about how we store and use your data. We at LUDD have therefore set up a Privacy Policy showing what data we store, how we store it and your options when you want to change your data.
The Privacy policy can be found at: http://ludd.se/privacy
Nothing has really changed regarding your data. But now we have everything in writing.
So here is the last bullet for GDPR!
