You might remember my ramblings about apcupsd in a post yesterday. I asked for it to be removed as it turned out to be unrelated to B3. I found one of the problems was in my ubuntu installation.
I found another issue that you should be aware of though:
If you use Ethernet over your power lines (like with D-Link Powerline 500 or similar), and you have an NFS mount on the machine on the other end of the “ethernet” link – be aware! When the power goes away, it doesn't seem to behave like a proper computer dying on the other end of the line.
I found I had to add statements like this in my /etc/apcupsd/onbattery files on the computers where I have apcupsd installed, or they would freeze up, even the b3:
Code: Select all
# Force unmount of popcorn NFS share immediately.
# It will not survive the powerout, and the network to it will be lost
# (D-Link Powerline)
# The first attempt will fail as the device claims to be busy, but the second
# generally succeeds, so do it twice...
# If this is not done, hangs and general weird behaviour can be expected.
/bin/umount -f /home/storage/mounts/popcorn || /bin/umount -f /home/storage/mounts/popcorn
