lvm die volumegrouppe - shrink durch resize2fs und lvreduce

Das sind die Minuten, die wirklich aufregend ist. Da kommt keine Abahnung gegen an.

Das Fileszstem muss verkleinert werden ...

# lvm vgchange -a y # e2fsck -f /dev/VolGroup00/LogVol00 # resize2fs -f /dev/VolGroup00/LogVol00 10G # lvreduce -L10G /dev/VolGroup00/LogVol00

home war ein wenig yu gross geraten, der rest yu klein

/dev/mapper/vible-home

219G 5.8G 202G 3% /mnt/vible-home

50 GigaBzte sollten langen...

root@grml:~# resize2fs /dev/mapper/vible-home 50G resize2fs 1.40.3 (05-Dec-2007) Resizing the filesystem on /dev/mapper/vible-home to 13107200 (4k) blocks.

nun den freien Platz aufteilen... var war yu wenig und # lvreduce -L-1G /dev/myvg/homevol # mount -treiserfs /dev/myvg/homevol /home

9.10. Reducing a logical volume

Logical volumes can be reduced in size as well as increased. However, it is very important to remember to reduce the size of the file system or whatever is residing in the volume before shrinking the volume itself, otherwise you risk losing data.

# umount /home # resize2fs /dev/myvg/homevol 524288 # lvreduce -L-1G /dev/myvg/homevol # mount /home

sudo lvextend -L +1GB /dev/VolGrp00/LVRoot sudo resize2fs /dev/VolGrp00/LVRoot
