Interrupted streaming replication

Hi all,

I have a small problem of my own making. I have a simple streaming replication setup, one master and two slaves. One slave is in the same rack as the master, the other is across a "slow" link in another server room.

Last night I executed some updates that caused a lot of changes. The slave in the same room did worked just fine, and the slave across the slow link was working fine, applying logs.

Then my backups executed, and moved all of the WAL archives, to an archive directory.

The good news is, I *think* I have them all.

The slave is waiting:

postgres 12562 12561 0 Oct16 ? 00:11:07 postgres: startup process waiting for 00000001000000890000002C

And I definitely have the file in my archive directory on the master.

The master is logging this error:

2015-12-07 08:24:50 EST FATAL: requested WAL segment 00000001000000890000002C has already been removed

Can I simply copy the file from my archive directory back to the WAL directory?

Thanks in advance
Tony Nelson
