Hi everyone,
I have a client preparing its switch to LMDB backend and in the testing
environement we have reached the 8GiB hard limit in ldb_mdb.c [1].
It is not very hard to rebuild the RPMS with a 16GiB limit, however I
had two question in mind :
* would it be possible to provide the size during the DC
provisioning/join (it would be fixed on a a single DC, but it could be
increase by joining a new one and removing the old one). And it would
perhaps help for the bugzilla 13630 [2]
* if I change the mmap_size, is there anything I should be careful about
if the lmdb file has been initially created with a 8GiB limit?
Cheers,
Denis
