The hostname Tomato is currently being used for the rackmount server which was previously known as Einstein. If you're looking for information about the system formerly known as Tomato, it has been renamed Okra.
General Information
Currently tomato isn't used for anything critical, but it does serve as a secondary DNS server and VMWare host.
Hardware Information
- Motherboard: SuperMicro H8SMU User Manual
- nVidia MCP55-Pro chipset
- SAS Backplane: SAS825TQ
- Marvell Technology Group Ltd. MV88SX6081 8-port SATA II PCI-X
Network Configuration
Tomato has an ethernet cable connected to the switch for local (farm) connection, and uses a vlan configuration for the connection to the external (unh) network.
- IP address UNH: 132.177.88.52 (eth1)
- IP address Farm: 10.0.0.248 (eth0)
- IP address IPMI: 10.0.0.148
Hot Swap Information
- Interesting thread to get sata-nv to hotswap: ([1])
- There are drivers available for the MB sata, we could try them: Super Micro MB H8SMU drivers, BUT these appear to be standard Nvidia sata_nv driver.
- SAS Backplane: SAS825TQ
- SAT2-MV8 8-port SATA controller. Uses the sata-mv module which is NOT HOTPLUG CAPABLE. (see http://linux-ata.org/driver-status.html#matrix). THE ONLY WAY TO "HOT PLUG" with this driver is to dismount ALL the drives, then "modprobe -r sata-mv" (make sure it is really gone: lsmod | grep sata) then do the swap, then "modeprobe sata-mv" again.
Special Considerations for Einstein (Historical)
This information no longer applies and is here for historical reasons. We no longer use amavisd, and so these instructions are not useful.
Einstein is our mail server. That means it runs "amavisd" (a virus scanner) and "spamassasin" a spam filter. Both these codes have some issues with leaving junk around, slowly causing the "/" file system to fill up. When that happens, einstein stops functioning.
Some cleanup can be done as follows:
- stop amavisd and spamassasin:
service amavisd stop service spamassasin stop
- clean out some of their junk:
rm /var/amavis/.razor/razor-agent.log touch /var/amavis/.razor/razor-agent.log chown amavis:amavis /var/amavis/.razor/razor-agent.log chmod o-r /var/amavis/.razor/razor-agent.log rm -f /var/virusmails/* # (Sometimes there are so many, you have to delete in "chunks") rm -rf /tmp
- start up the mail stuff again.
service amavisd start service spamassasin start
There may be other areas that can be clean up, as in all the archived mail from "mailman"? But at least this list will let einstein function again.
