Shrink LVM root partition<\/p>\n
Ok, I’ve figured this out … so just in case anyone wants to know how to do it:<\/p>\n
1. Write the FC rescue disk ISO onto a CD, and reboot the machine from it.
\n2. Do not mount the file systems.
\n3. At the prompt, type:<\/p>\n
lvm<\/p>\n
4. Within LVM, run these commands (comments are after the ‘#’s):<\/p>\n
lvm> vgscan # Will show the name of the Volume Group
\nlvm> vgchange –available y VolGroup00 # Activates the VG and the LVs in it
\nlvm> lvscan # Should show the LVs as “ACTIVE”; the devices in \/dev it mentions should now exist
\nlvm> exit # Quit, return to the prompt<\/p>\n
5. Now resize the filesystem with this command (e.g., using device \/dev\/VolGoup00\/LogVol00):<\/p>\n
e2fsck -f \/dev\/VolGoup00\/LogVol00 # fsck on the filesystem
\nresize2fs \/dev\/VolGoup00\/LogVol00 nnG # resize the fs to nn GB; nn should be less than the current fs size
\ne2fsck -f \/dev\/VolGoup00\/LogVol00 # Do another fsck on the filesystem; fix any errors which appear<\/p>\n
6. Run lvm again and type:<\/p>\n
lvm> lvreduce -LnnG \/dev\/VolGoup00\/LogVol00 # Resize the LV to nn GB; nn should be the same as above
\nlvm> exit # Quit, return to the prompt<\/p>\n
7. Finally, do another filesystem check:<\/p>\n
e2fsck -f \/dev\/VolGoup00\/LogVol00 # Do another fsck on the filesystem; fix any errors which appear<\/p>\n
8. Remove the CD and reboot.<\/p>\n
