disk space shortage, how to migrate to LVM?
Hello
I'm working on AIX 6.1. I inherited something I do not know and now I need to bring it into the line.
# df -m
Filesystem MB blocks Free %Used Mounted on
/dev/hd4 | 256.00 | 87.09 | 66% /
/dev/hd2 | 4608.00 | 82.45 | 99% /usr
/dev/hd3 | 256.00 | 212.34 | 18% /tmp
/dev/hd1 | 256.00 | 1.95 | 100% /home
[cut]
/dev/lv02 | 65024.00 | 60709.92 | 7% /home/users
/dev/lv03 | 65024.00 | 65001.13 | 1% /temp
Now you know why I'm asking of some help.
I'm running out of space on /dev/hd* :|
I have plenty of free space on other drives so I can set up few more LVMs.
Is there any easy way to migrate my files from running-short filesystems to LVMs?
I think that I should prepare lvm, copy all files from such fs and then modify /etc/filesystems to point new disk space for a mountpoint.
Am I correct?
Is there some magic command for such copying?
Do I have to reboot to check whether it works?
Best regards
michael
