<div class="moz-cite-prefix">That's the way I've always have done it
in the past, but up through f 19 fstab did not go through systemd.
The change seems to be in F 20 as fstab now has references to
systemd. I have tried using formats from the past in the lines of
volumes that I added in fstab,but it won't work. I know with
services you now use systemctl <command> <servicename>
on systems with systemd. From what I can tell you need to do
something similar and can't just add a line in fstab. What I can't
seem to find is what this new/extra step(s) is/are. Everything
just seems to go into an endless loop. (No pun intended,
maybe?!?!). I did notice that the way the installer does it in F
20 is to create the LVM containers first pvcreate and vgcreate
before creating the LUKS container then lvcreate. At least that's
what it seems to be doing, whereas in the past it would do the
LUKS stuff 1st then the LVM stuff.<br>
<br>
One thing that I ran into that the naming of the lv must be the
same as the mount point name.<br>
ie. lvcreate -L 400G -n pub_Music /dev/mapper/ncc1701_03<br>
/dev/mapper/ncc1701_03-pub_Music /pub/Music ext4
defaults;x-systemd.device-timeout=0 1 2<br>
<br>
you can't use pub_audio for the lv name and mount it at
/pub/Music, if I'm understanding this correctly, which makes no
sense to me. But I think I've already ruled that out as I did go
back and redid it so the names matched and I still wind up at
maint mode. That's if I only uncomment one entry in fstab, if I
uncomment all the added entries it never boots just gets caught in
a starting job for fsck loop counting through 1 - 8 for each lv
and starting all over again.<br>
<br>
I'm thinking about just blowing off my current install and doing
the full setup through the installer. Unfortunatelly I have never
been able to run the installer with out reformatting all but the
/home filesystems since F 19<br>

those commands backwards. If you want to create an encrypted
drive ala the installer I think you need to cryptsetup, then
pvcreate, then lvcreate, then mkfs. This mirrors what my
encrypted system looks like. The lvm is inside the crypto.<br>

<div>I know the encrypt drives process JustWorks during
_installation_ of F20. I'm 90% certain it encrypts the
contents of an LVM and not the other way around. If you
encrypt a container that holds PVM/LVM IDs, the kernel
will not know how to use it (I think - still digging in
systemd as well). Also, F20 is using grub2 which is also
a vertical learning curve.<br>

I think you need to go the following order:<br>
<br>
</div>
pvcreate<br>
</div>
<div>lvcreate<br>
</div>
cryptsetup<br>
</div>
mkfs<br>

understand the changes made to filesystem mounting at
boot-time in Fedora 20? Apparently systemd now controls it
all? The reason i ask is that when I had originally upgraded
to F 20 I had setup all 5 drives in the installer. Since
then everytime the door leading to the garage, under the
room my systems are in, slams shut it causes the floor to
pop up and my system will sometimes jump. Normally everyone
is careful about opening and closing this door and I had
also moved the computers over to the other side of the room
the last time I went through the hassle of crashed drives.
This one day was exceptionally windy and the door really
slammed hard. Immediately I started getting warnings of
read/write errors, bad sectors, etc., etc. on one drive then
2 more drives suddenly unmounted. The system then rebooted
itself and never came back up.<br>
<br>
Since it was toast I went ahead and ran smartctl tests
followed by badblocks which pointed to my 4th drive (hmm not
the 5th or 3rd drives). I then ran dd if=/dev/urandom
of=/dev/sd? on the remaining 4 drives. I did the boot drive
seperately so that I could get my system at least partially
back up. I reinstalled F 20 with just the one hdd figuring
that the remaining 3 drive I could manually add back in. By
the way I don't use raid so that is not to be figured into
my problem, I do however setup LUKS on the raw device
followed by LVM. My steps are:<br>
<br>
1. cryptsetup luksFormat /dev/sd? (exact syntax maybe wrong
as I'm doing this by memory which admittedly has gone
downhill lately).<br>
<br>
2. blkid /dev/sd? (to get the luks UUID of the drive for the
next 2 steps)<br>
<br>
3. cryptsetup luksOpen /dev/sd? luks-<Block UUID ><br>
<br>
4. pvcreate /dev/mapper/luks-<Block UUID ><br>
<br>
5. vgcreate <name used for vg>
/dev/mapper/luks-<Block UUID ><br>
<br>
6. lvcreate -L <size of lv> -n <name of lv>
<name of vg><br>
<br>
7. mkfs.ext4 /dev/mapper/vg-name/lv-name<br>
<br>
8. I'll go ahead and mount it where I plan to mount it in
fstab and verify that all is well.<br>
<br>
9. Add the luks UUID in /etc/crypttab and enter the mounting
info of the lv in fstab. (This is where it is different. I
noticed that the mount options part is different from the
past in that it'll have "defaults;x-systemd.device-timeout=0
1 2" on lvs that were created by the installer. So I
duplicated this for the lvs that I added.<br>
<br>
10. Unmount lvs, close luks volume and reboot.<br>
<br>
The system will then either hang on boot or dump out to
maintenance mode when trying to mount my lv. I can however
manually mount the lv and the boot will continue. So what's
the deal? Anyone know? This is the way I've done it in the
past with NFP. I found the docs on this very confusing in
that it keeps on referring to something else which will
refer to something else again, so on & so on, eventually
it goes around in a circle.<br>
<br>
Hellllppp Meeeeeeeeeeee (in my best human-fly imitation from
the spider web).<br>
