2.3 uses 64-bits (long long int) on systems that support it.
I wonder if this is still true for 2.2.10. I set my quota to 3 GBs and it seems to work OK:
cyrus.rrz.uni-koeln.de> sq user/a0620 3000000 quota:3000000 cyrus.rrz.uni-koeln.de> lq user/a0620 STORAGE 297144/3000000 (9.9048%) [EMAIL PROTECTED] imap]$ quota user/a0620 Quota % Used Used Root 3000000 9 297163 user/a0620
Am I missing something?
The limit is measured in Kbytes where the usage is measured in bytes. So, while you can theoretically set the limit to 2TB (2GB * 1KB), the usage is still limited to 2GB (32 bits). Did I explain this clearly? Reading it myself, I'm not sure I did. ;)
I'm glad you wrote that, because I'm not sure I understand ;-) I get the difference between limit and usage. What I don't get is when precisely this becomes an issue. If I've got a limit > 2 GB all usages up to 2 GB should be OK, because neither value overflows its variable, right?
That is also my understanding.
If the usage goes over the 2 GB limit, I assume it would roll over? So the worst case scenario would be that quotas > 2GB equal no quota!?
Yes, the usage would overflow. I'm not sure how the overflow will be seen by the client/server. I'd have to check the code.
But this analysis does not mesh with the following statement:
I set a user to have a 10 gigabyte quota and the user was treated as being over-quota with just 10 megabytes.
How does that happen? Is it that the difference between limit and usage is measured in bytes and is also 32 bits? That might explain it ...
This doesn't make sense to me. Perhaps the person that reported this didn't realize that the limit is set in Kbytes, not bytes, and somehow messed up their math.
