Re: [gentoo-user] LVM, /usr and really really bad thoughts.
Hello! 2012/3/11 Canek Peláez Valdés can...@gmail.com: The next step was to remove /usr from /etc/fstab to prevent /usr from being mounted twice (the boot process does not like it). Mmmh. Could you try to use LABEL= in /etc/fstab (not /etc/fstab), and see if that way it gets mounted, and only once? The udev developers recommend using either UUID or LABEL; and LABEL it's easier (and prettier) to set. I actually did not remove it: /dev/mapper/vg-usr /usrext4noauto,noatime 1 2 I am afraid of what would happen if I remove noauto. As far as I recall the boot procedure aborted. The last obstacle is /etc/mtab. By the time /usr is mounted I believe / is mounted as read only, so mount cannot update /etc/mtab. The trivial solutions is to delete /etc/mtab and make it a symlink to /proc/mounts . In that case it is always up to date. I think the link is to /proc/self/mounts; /proc/mounts it's a link to it, actually. You are right.

Re: [gentoo-user] LVM, /usr and really really bad thoughts.
Hi! I had some struggle with a separate /usr on top of LVM and the dracut thing. I noticed that udev was complaining at boot that it could not find some scripts. The usmount dracut module did not work for me because it could not find /usr. So what I did was to include the fstab-sys smodule in dracut: /etc/dracut.conf # Dracut modules to omit omit_dracutmodules+=usrmount # Dracut modules to add to the default add_dracutmodules+=fstab-sys Then I created /etc/fstab.sys with just the /usr partition /dev/disk/by-uuid/90d82b02-e6c2-4011-940e-783d12b0c4fe /usr ext4noatime 1 2 Dracut could only find the partition by using the uuid (use blkid to find it easily). The next step was to remove /usr from /etc/fstab to prevent /usr from being mounted twice (the boot process does not like it). The last obstacle is /etc/mtab. By the time /usr is mounted I believe / is mounted as read only, so mount cannot update /etc/mtab. The trivial solutions is to delete /etc/mtab and make it a symlink to /proc/mounts . In that case it is always up to date. Of course, YMMV. Be careful when changing things that can prevent your machine from booting and make sure you have a live CD at hand.

I'm wanting to keep / (root) on a normal ext4 file system. I want to put /usr, /var, /home, and such on LVM. I been using that dracut thingy to build the init thingy. Sorry, I'm full of thingys tonight. Maybe I need my meds? Anyway, the init thingy seems to be working, I think. I asked a while back how to tell for sure but it didn't get any replies so I am not real sure it is.

I need to make certain before diving into the next step. I have a second drive that is plenty large enough. Thanks Kashani. I plan to move everything currently to the larger drive then just sort of do a fresh install on my regular OS drive. One question I have right off the bat, how do I tell dracut to mount /usr? I think it used to have a usr USE flag but that seems to have disappeared during a upgrade. Is it magic? Does it need to mount /var as well for logging? Just for the record, dracut is the only way I could get a init thingy to build and let me boot. I tried different ways and they just didn't work. At least I think dracut is working which is a good start. ;-) I hope there is a few dracut users on here that have at least /usr on a separate partition. I keep my /usr partition in /, but seeing the modules from dracut, the magic happens at: /usr/lib/dracut/modules.d/98usrmount/mount-usr.sh Basically, it seems that if /usr is specified in /etc/fstab, then dracut will mount it. It says nothing about LVM, but that is taken care of in the scripts at: /usr/lib/dracut/modules.d/90lvm I'm not familiar with LVM, but it seems simple enough. And you can create and modify your own dracut modules, of course. Regards. -- Canek Peláez Valdés Posgrado en Ciencia e Ingeniería de la Computación Universidad Nacional Autónoma de México

I would say it's using an initramfs; if you only specify the dracut created one in grub or lilo, that should be the one.

Finally, and it's none of my bussines, but reiserfs? Seriously? Regards. Well, that is one of the things I want to change. I have several reasons for wanting to change this mess. One is a file system change and the other is to use LVM for stuff. I basically want LVM for everything but root itself and /boot of course. Right now, /usr is still on the root file system. I have portage on a separate partition tho. So far, reiserfs has not gave me any problems, not OS wise anyway. I did have a large drive that gave me issues but I'm not sure if it was the file system or not, tho it could very well have been. It now has ext4 tho. lol I'm going to beat some sense into this other drive and make a few partitions. I may not do this tonight but then again, I might. ;-) Dale :-) :-) -- I am only responsible for what I said ... Not for what you understood or how you interpreted my words! Miss the compile output?
