Trac regularly unavailable with no space left on device

[btlogy]

This unavailability has been observed already a few time before (at least since #4095 last year), but seems to happen on daily basis since a few last weeks (end of March 2025).

See this list of past ​incidents.

The error show by the Trac software seems to be explicit:

IOError: [Errno 28] No space left on device

In addition to the service being often unavailable (to create and manage this issue for instance), one could be concerned of the increased risk data of corruption.

Meejah has been made aware of this problem on IRC and will hopefully be able to at least free some disk space (maybe 18th or 19th of May).

But 2 questions remains:

• could the root cause be identified to increase the availability and reduce the risk of corruption (if any)?
• is there a backup to restore the data in case those would end being corrupted?
