Please help with rearranging file system
Currently all my file system is in one VolGroup00, such as LogVol00 is mounted as /, LogVol01 is swap (unmounted), LogVol02 is mounted as /usr, LogVol03 is mounted as /tmp, LogVol04 as /var, and logVol05 as /home.
I used most of the available space in VolGroup00 for /home, leaving about 21GB for /tmp. Now some programs quit because there is not enough space on /tmp, even if I clean it up. So I want to add more to /tmp, but there is no more extents as all is given to /home.
I added 4 more disks, formatted them as ext3 and combined them as one VolGroup01. Now I would like to move the entire content of the LogVol05 to VolGroup01, unmount LogVol05 from /home, mount VolGroup01 as /home, clean up LogVol05 and then use the freed space to add more extents to other LogVols in VolGroup00, including increasing LogVol03 (/tmp). Can I do that and what is the safe way of doing this?
