Extending root RHEL physical partition and then the underlying LV

Bit fiddly this so reminder to myself:
  • Boot into rescue mode from install DVD
  • delete partition with fdisk 
  • recreate at same start to end of disk
  • reboot
  • back into rescue
  • Then run these commands
pvresize /dev/sda2 (or 2nd partition on physical disk)
lvextend /dev/mapper/*vg_lv* -l+100%FREE (for all the disk)
resize2fs /dev/mapper/*vg_lv* (to resize FS, may take a short while)
  • Check volumes are ok with vgs/lvs
  • Reboot to double check everything boots and mounts fine

Manually patching vSphere 5.0 free edition

As the free edition can't use update manager a quick and easy way to patch a single host is to download the latest patch from VMWare and upload to an accessible datastore then put the host into maintenance mode.
Then enable SSH on the host, login and run:
esxcli software vib install -d /vmfs/volumes/datastore/patchfile.zip
It'll take a while and you should get results that say it's all been sucessful and you need to reboot.
