Title: pretce and LVM won't work
Post by: sebelk on April 03, 2012, 10:00:15 PM

Hi,

I'm using TCE 4.4 Core Plus, I've tried to use a backup restore on a logical volume.

I've followed the documentation at http://wiki.tinycorelinux.net/wiki:pretce

Sadly it doesn't work

 I've configured grub2 as follows:

Code: [Select]

menuentry TinyCore {
set root=(hd0,3)
linux /tce/boot/vmlinuz max_loop=256 pretce=sda3/pre tce=dm-2
initrd /tce/boot/core.gz
}
More data:

[root@pc sergio]# ls /boot/tce/
boot  mydata.tgz  onboot.lst  ondemand  optional  xwbar.lst
[root@pc sergio]# cat /boot/pre/onboot.lst
lvm2.tcz
lvm2-boot.tcz
 mount | grep sda3
/dev/sda3 on /boot type ext4 (rw,relatime,user_xattr,acl,barrier=1,data=ordered)

Please could you tell me what I am doing wrong?

Make sure your pre/optional directory is properly populated.
See all the needed extensions in the "Depends" panel for lvm2 in AppBrowser.

Thanks Finally I've got it.

I've populated the pre/optional directory as you suggested:

libdevmapper.tcz             ncurses.tcz
liblvm2.tcz                  raid-dm-3.0.21-tinycore.tcz
lvm2-boot.tcz                readline.tcz
lvm2.tcz                     udev-lib.tcz
ncurses-common.tcz

Also, I've added the list to pre/onboot.lst

readline.tcz
ncurses-common.tcz
ncurses.tcz
udev-lib.tcz
libdevmapper.tcz
raid-dm-3.0.21-tinycore.tcz
liblvm2.tcz
lvm2.tcz
lvm2-boot.tcz

I've found that order is important, isn't it?

And I replaced tce=dm-2 with tce=dm-0
For some reason Fedora and tinycore see that volume on different device

HTH

They are dependencies. You do not need to add them to the onboot.lst.
You do need the .dep files in pre/optional, though.

I suspect you did not do the following part of the instructions:
Boot with the options: tce=sda1/pre.
Run tce-load -iw lvm2.

That would have loaded the extensions and dep files for you.
