I am still debating about whether to move to this Raid 5 or not, but here is the current story.
I am running an XFS filesystem, and I recently added a 200G harddrive to my LVM group. I believe it is linear and I don't think my /video has gotten big enough to start using the 200g (if it is in fact sequential). Problem is, I think the 200G is dying. Is it possible to remove this from the LVM group and revert back to just my original 1HD LVM?? I added the 2nd hard drive with the following commands: Extending an LVM Partition 1. Using fdisk, created /dev/hda4 as LVM 2. Created physical volume: pvcreate /dev/hda4 3. Extended volume group: vgextend VideoGroup /dev/hda4 4. Ran vgdisplay to determine space to be extended (free space) 5. unmount the volume group: umount /dev/VideoGroup/VG01 6. extend: lvextend -l +18214 /dev/VideoGroup/VG01 7. mount /dev/VideoGroup/VG01 8. grow the xfs file system: xfs_growfs /dev/VideoGroup/VG01 ... can I undo this? (On a side note, I also think I would like to backup my linux so that if it ever dies I can restore it and not have to setup everything again. I am currently rsyncing a whole bunch of directories to a nfs drive. Is this enough? I am worried that if I tar or rsync the proper directories that I will be missing some hidden/system files... or is this just worries leftover from the windows days?) This also leads to the questions 1) What tar commands should I use to make a backup of my system that I can easily restore-and-go? 2) i am rsyncing all of my directories off of the root except the following: (does this look good, or should I be rsyncing some of these as well?) /video /proc /dev /sys /tmp /mnt (sorry for all the questions. you guys are like my mentors now...) dave _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
