\n\tI recently installed CoreOS on my HP DL360 G5 and notice that even though I setup a hardware-raid 5 with 6 72GB SAS drives, my ninth partition was only 2GB in size.\n<\/p>\n

\n\tAfter some research I found out that CoreOS is supposed to enlarge the ninth partition automatically but that didn't happen for my DL360, so I went digging.\n<\/p>\n

\n\t \n<\/p>\n

\n\tAfter a quick google search I saw that there is a patch for that:\n<\/p>\n

\n\thttps:\/\/github.com\/coreos\/bugs\/issues\/1037<\/a>\n<\/p>\n

\n\tUnfortunatelly it doesn't seem to be in the stable channel (at the time of my installation), so I was trying to manually apply the change, which then made me realize that \/ and \/usr are mounted read-only.\n<\/p>\n

\n\tSo I checked what \/usr\/lib64\/coreos\/extend-filesystems<\/strong> does and I had only to issue the following commands as root:\n<\/p>\n
