Just extend its size by 1G, without unmouning: lvresize -L +1G /dev/myvg/lvm1 The volume groups is getting full, no space to add LVMs? Add other partitions.

Once you have LVM, you do not have to care what the actual device names of your drives are. If sda becomes sdb and vice versa, no problem, and nothing to worry about. LVM does not use the device name, it scans each partition and uses the LVM UUIDs on them to identify what is what. Wonko Since I finally got this thing settled with partition sizes, that's pretty complicated. I have root, /boot, /home, portage and a data partition for misc. junk. I doubt it will change any in the near future. I did read up on it one time a while back. It's neat when you have to add drives and resize things but still a bit much for a little desktop. I'd stay away from LVM. I started using it on a Debian Lenny machine and performance went down the drain. For example, deleting a 3GB file was almost instant and now it takes like 15 seconds. It's almost as if with LVM, deleting a file means writing 0 all over the 3GB first :-/ That sounds like a different issue. I haven't noticed any major performance issues myself. But to test quickly: LVM: # ~/speedtest $ time dd if=/dev/zero of=3gigfile bs=1024 count=300 300+0 records in 300+0 records out 307200 bytes (3.1 GB) copied, 33.3029 s, 92.2 MB/s real0m33.305s user0m0.440s sys 0m16.370s # ~/speedtest $ time rm 3gigfile real0m3.827s

Well, once done, it is done. Dale :-) :-) Another hiccup for the record. When you add/change a label, you have to reboot for it to take effect. At least that was what I did anyway. The labels didn't show up until I rebooted. Sort of funny in a way. I have changed partition layouts before and them take effect without a reboot. Maybe I should have restarted udev? Also, I first booted a Gentoo 10.1 DVD and all the drives showed up as sd**. I didn't see a hd* in the list anywhere. So, if you are not SURE what each drive will be, boot something that doesn't use the PATA drivers. For me, I booted a old Gentoo 2006.1 CD. That listed both hd** and my sda drive. I didn't try my Knoppix disc tho. I'm not sure what drivers it uses. Now to figure out how far off the deep end I want to go with editing fstab. Going to read some replies here and a man page or two. ;-) The way I figure it, once I edit fstab and get it to boot correctly, it shouldn't matter whether the drives use IDE or PATA drivers. Then I can work on the kernel next. Dale :-) :-) P. S. Any way to label swap? It's not reiserfs or ext*.

It could be either way. But, we all know how flexible grub is. You can just use TAB to autocomplete and try. All you need to boot is your root fs, after that fdisk -l will reveal all the info you need. fstab is another story, that might cost you an extra reboot into a livecd to fix it. Another thing that I hadn't thought of, grub. I didn't even think about grub would have to be edited. That would have been interesting when I tried to boot up. You just need to feed linux with the right parameters, so it finds the root filesystem. Grub id's themselves should remain the same, I suppose. Also, as GRUB allows you to edit commandlines, you can do this by trial and error (but a good initial guess is still worth it). -- Nuno J. Silva gopher://sdf-eu.org/1/users/njsg

Just extend its size by 1G, without unmouning: lvresize -L +1G /dev/myvg/lvm1 The volume groups is getting full, no space to add LVMs? Add other partitions. If you like, even from a 2nd drive: pvcreate /dev/sdb5 vgextend myvg /dev/sdb5 So, it's of course more complicated than just firing up cfdisk, create partitions and file systems on them, but you have much more flexibility. Once you have LVM, you do not have to care what the actual device names of your drives are. If sda becomes sdb and vice versa, no problem, and nothing to worry about. LVM does not use the device name, it scans each partition and uses the LVM UUIDs on them to identify what is what. Wonko Since I finally got this thing settled with partition sizes, that's pretty complicated. I have root, /boot, /home, portage and a data partition for misc. junk. I doubt it will change any in the near future. I did read up on it one time a while back. It's neat when you have to add drives and resize things but still a bit much for a little desktop. I'd stay away from LVM. I started using it on a Debian Lenny machine and performance went down the drain. For example, deleting a 3GB file was almost instant and now it takes like 15 seconds. It's almost as if with LVM, deleting a file means writing 0 all over the 3GB first :-/

I would think the main drives in a system would come first but one could never make that promise. I'm giving serious thought to using the labels. It would also mean that I don't have to remember what partition is what. Currently I would mount and then list what is in the directory to see what is in it and figure out what it is. With the labels feature, even fdisk would tell me what is what. This would be a good time to move the OS to a new drive. If things work out, run from the new drive. If things blow up, boot the old drive with the old kernel, old fstab and other settings. Thanks. Dale :-) :-)

As I have everything on LVM (except for the /boot partitino, which is on an USB stick), my drives are identified by their volume group. /dev/weird is the system drive, /dev/weird2 is the identical backup drive. This way I do not have any /dev/sdX in either fstab or grub.conf. And when the system drive fails, I vgrename wird2 to weird, and then the backup drive will become the system drive. Wonko It would be nice if something like *fdisk could edit the labels tho. It would be so much easier. I didn't see anything in the man pages tho. I looked into LVM a good while ago. It's just to much for me to keep up with since I just have a desktop system here. It has its good points but just way overkill for what I have here. It seems as time goes on, things get more complicated. lol Dale :-) :-)

It's a burner. sda Actual hard drive connected through a SATA PCI card. Misc stuff. The advice by the other posters to label your disks is a good one. I'm using labels too. Not sure why I didn't think to mention it :P Applying labels to your filesystems is trivial. Simply use the e2label utility (it's in the sys-fs/e2fsprogs package and installed by default, so there's nothing new to emerge). For example, if your hda1 is your root partition and your hda2 your swap, you can label them like this: e2label /dev/hda1 GentooRoot e2label /dev/hda2 GentooSwap Note: hda1, not just hda. You are labeling the filesystem on a partition, not the whole drive. After you label all your filesystems, you simply modify your /etc/fstab like this: Before: /dev/hda1 / ext4 noatime 0 1 /dev/hda2 none swap sw 0 0 After: /dev/disk/by-label/GentooRoot / ext4 noatime 0 1 /dev/disk/by-label/GentooSwap none swap sw 0 0 That is, you simply change /dev/blah to /dev/disk/by-label/DriveLabel and that's it. Yet another way to use labels: When you make the filesystem, apply the name then i.e.: mke2fs -j -L SpeedySSD /dev/sde1 then in your /etc/fstab use the label like this: LABEL=SpeedySSD /usr/home ext3 relatime 0 2

That way I can boot it and see exactly how it will name them and what drive is what without actually changing anything at all. Is there a boot option noide or some other switch I can use? Afraid not. The naming scheme is, officially, not constant and can change with reboots. On my server, with hotswap, I get different device-names when I remove a disk and plug it back in. Eg. /dev/sdb - /dev/sdj (as example) Don't think you'll have that particular issue, but having these names change between reboots is possible. Especially if a drive fails and is not found during boot or a new drive is added. Not tested, but I believe USB-drives might also get pushed into the mix? -- Joost I do know the USB stuff changes but I wasn't sure about the others. I would think the main drives in a system would come first but one could never make that promise. I'm giving serious thought to using the labels. It would also mean that I don't have to remember what partition is what. Currently I would mount and then list what is in the directory to see what is in it and figure out what it is. With the labels feature, even fdisk would tell me what is what. This would be a good time to move the OS to a new drive. If things work out, run from the new drive. If things blow up, boot the old drive with the old kernel, old fstab and other settings. While on the topic of labels, is there a way to change the label of a reiser4 partition, *after* it has been created?

I think it's common to do things this way on RedHat systems, maybe with some other distros - that's what fouled me up when I tried using labels in GRUB; I just found grub.conf examples using them, and was unaware of this requirement.
