Hi,

we have two servers running nfs and postgresql7.4 on one partition shared with drbd 0.7.10-1
(heartbeat for ha).

After 6 months of utilisation in production environment, we saw a degradation of the access rate to
the partition shared.

So it cause low answer of postgres and low access to nfs.

Have you ever heard this type of problem on drbd?

Do you know if there is tuning to do in configuration, especially max-epoch-size, max-buffers?
We let the configuration the more standart as possible and we ran the C protocol, the servers are
connected with 1 Gb network card.

Thanks
