Ojs 188.8.131.52, everything worked fine for more than 2 years.
Following a failed entire site backup (finished with “not enough space on disk”) some errors (malfunctions) appeared :
all the archives (the list which displays the published issues) displays now a white page (the header disappears).
some sorting (by author, title) works, some display a white page with\without header.
some created pages with the custom page creator are displayed some are not (blank page \ with or without header).
All other functionalities seems to work, published articles are still on their places.
Accessible only if having their link \ address, not by browsing issue, article list (the article lists exist, the issues exist, only the list of the issues is gone).
Yes, it’s likely that filling up the disk caused this due to a corruption in the cache.
The database should include reasonably robust integrity checks, so I think the likelihood of your database being corrupted is pretty low.
I’m not a server administrator so I’m less well versed in good practices for managing server space, but it’s pretty common to run your backups onto a different filesystem so that an out-of-control backup won’t take down other services. Other kinds of segmentation (e.g. keeping your database data on a different partition) might also be useful. Our servers generally include a notification tool for when space gets low, but if your backups run at 3am and there’s no sign of trouble until then, it wouldn’t save you in this circumstance.

Thank you very much for your help.
Things appear to be stable after the cache cleaning.
We checked the database and all seems OK.
We will take care in order to avoid disk space incidents on the future.
