I am trying to solve an amcheck error.
"Amanda Backup Client Hosts Check" errors with"selfcheck request failed:
timeout waiting for ACK".
I am simply trying to backup the local host (mother_inner) to a local tape
drive (HP-LTO4).
T
his is amanda-2.6.1_p2 on a 64bit gentoo machine, using xinetd.
Full output of amcheck:
su amanda -c "/usr/sbin/amcheck Monthly_Mother"
