So: the matrix.org database secondary lost its FS due to a RAID failure earlier today (11:17 UTC). Then, we lost the primary at 17:26. We're trying to restore the primary DB FS (which could be fastish), while also doing a point-in-time backup restore from last night (which takes >10h).

Sorry, but it's bad news: we haven't been able to restore the DB primary filesystem to a state we're confident in running as a primary (especially given our experiences with slow-burning postgres db corruption).

So we're having to do a full 55TB DB snapshot restore from last night, which will take >10h to recover the data, and then >4h to actually restore, and then >3h to catch up on missing traffic. Huge apologies for the outage. Again, folks using their own homeservers are not impacted.

Why is the database that large? That seems like a lot for just text.

Other servers are unaffected of course, but despite many years of development Element still lacks multi account support.

Status update: we’re 47TB through restoring the 55TB db snapshot of the matrix.org DB, but then have to rebuild the DB and replay the subsequent 17h of DB traffic, which will take several hours. Thank you for your patience, and apologies once again for the outage.
