I saw that, but here it will be much easier. All is on LVM here, so this should do it: |
| 18 |
|
| 19 |
# enlarge root partition |
| 20 |
lvresize -L +17G /dev/weird/root |
| 21 |
cryptsetup resize root |
| 22 |
resize2fs /dev/mapper/root |
| 23 |
|
| 24 |
# make sure /usr is not being written to. For other partitions, I'd |
| 25 |
# create an LVM snapshot |
| 26 |
mount -o remount,ro /usr |
| 27 |
|
| 28 |
# mount root to another place, without mounts like /usr showing up there |
| 29 |
mkdir /tmp/bindroot |
| 30 |
mount -o bind / /tmp/bindroot |
| 31 |
|
| 32 |
# copy data over |
| 33 |
rsync -ax /usr /tmp/bindroot/ |
| 34 |
|
| 35 |
# remove /usr stuff from fstab and dmcrypt |
| 36 |
sed "/\/dev\/weird\/usr/ d" /etc/fstab |
| 37 |
sed -i "/^target=usr2$/{N;N:N:d}" /etc/conf.d/dmcrypt |
| 38 |
|
| 39 |
# done! |
| 40 |
reboot |
| 41 |
|
| 42 |
No need for downtime except for the reboot, I guess I cannot unmount /usr |
| 43 |
otherwise. |
