OkChicken

A geek community web server run by OliBye and KevinHutchinson (O&K) @ http://www.OKChicken.com

• Email on xpdeveloper is suffering after a power cut in the DataPantry?.
• • Random areas of /var seem to have been affected.
  • Mainly stopping the delivery of email to spool files (they remain as tXXX in /var/spool/mqueue).
  • e2fsck on the rescue oldroot fixed things. Debian Woody's e2fsck 1.27 complained that it was too old, when I tried it from single user mode. RecentChangesBug?

• The server has now been upgraded to run Stable Debian. Which wasn't a moment too soon, as on in October 2003 somebody had hacked the root account.

• Having some problems with tomcat. Rolled back to debian packaged tomcat4.

Why Debian? (I take it that Red Hat is distro non-grata because of the dubious licensing.) --DafyddRees

• not using a lot, and running out of space

• http://www.tldp.org/HOWTO/LVM-HOWTO/index.html
• Stripes shouldn't include Physical Volumes from same disk => make 4 stripped volume groups.

• Use fdisk to make Physical Volumes (0x8e)
• • /dev/hdb5
  • /dev/hdb6
  • /dev/hdb7
  • /dev/hdb8
  • /dev/hdd5

• Create Physical volumes

pvcreate /dev/hdb5
pvcreate /dev/hdb6
pvcreate /dev/hdb7
pvcreate /dev/hdb8
pvcreate /dev/hdd5

• Create the volume group for these PVs that will be used for stripes

vgcreate harddiskb /dev/hdb5 /dev/hdb6 /dev/hdb7 /dev/hdb8

• Create a 10G LV for distro
