Storage migration

Update 21:00 – IGP shares are back. Welcome to igp-data!
Update 19:30 – the D-PHYS shares are back. IGP will take a little more time.

In order to guarantee sustained performance and availability of our storage system, we need to schedule a few storage maintenance windows. The first one will take place on Wednesday, 12.12.2018 at 16:00 and affect all D-PHYS and IGP group shares, but not IPA or galaxy (technically: windata/macdata, but not astrogate or ipa-data). The relevant shares will be offline for at least 3 hours.

For emergency cases, there will be read-only access to last night’s backup as described here.

Please note that these migrations will bring some overall changes to the D-PHYS storage setup:

  • the SMBv1 protocol will be disabled on all file servers. It has a long history of security issues and we’ve migrated all clients to newer versions, so this should not affect anyone. However, there’s a small chance that we didn’t catch all connections, so please contact us if you experience any issues after the migration.
  • all SMB protocol versions will be restricted to ETH-internal access. This step has been long overdue and since most ISPs block the necessary ports anyway, it shouldn’t affect too many users. What it means however: in the future, file server access from outside ETH requires VPN.
  • IGP/D-BAUG will get their own front-end server igp-data. If you’re with IGP and have already switched your file server mounts from windata to igp-data, you’re good and don’t have to do anything. If you haven’t, you should do so before Dec 12 in order to get a seamless migration experience.

We’ll update this post as the migration progresses and as soon as the systems are back.
