So long as there's a partition that is _only_ for data on Drive 1 (hda3, for instance) everything should be workable. (If the whole 1st drive is one big partition, you're probably out of luck.)
/dev/hda1 / <-- main linux /dev/hda2 swap <-- swap space /dev/hda3 /myth <-- Myth data Create lvm partition on Drive 2. (/dev/VGforTV/tv) Mount lvm. Move data from /myth to /dev/VGforTV/tv Unmount /dev/hda3 mkdir /myth mount /dev/VGforTV/tv /myth/tv mv /myth/tv/* /myth edit fstab to mount /dev/VGforTV/tv /myth/tv prepare /dev/hda3 for lvm unmount /myth/tv extend VGforTV onto /dev/hda3 extend VGforTV filesystem to the new limit mount /myth/tv Basically, make a new lvm drive, copy all the data on /dev/hda3 over to it, unmount /dev/hda3, make a /myth directory, mount the lvm (all previous /dev/hda3 files/directories) onto /myth/tv. The directory structure will look like: /myth/myth /myth/myth/tv /myth/myth/video So, move all that stuff back one directory so you have /myth /myth/tv /myth/video At this point, /myth, /myth/video, and all the other files are back in /myth where they belong, and /myth/tv is a mount point for /dev/VGforTV/tv. This also gives you the freedom to mount a different lvm group onto /myth/video if you want. After that, unmount /myth/tv and prepare the /dev/hda3 to become part of the VG. Extend the volume group, then extend the file system. Remount, and voila! But, if your linux install is just: /dev/hda1 <-- install /dev/hda2 <--swap You'll most likely have to reinstall anway. But, you can still make the LVM on Drive 2 and back up your data! (Don't forget to get backups of your mysql database!) Anyway, hope this helps. --Phill W _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
