Bug 1552 – bug in startup scripts concerning LVM

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Thilo Bangert (RETIRED) (RETIRED) 2002-04-05 15:41:14 UTC]

Hi,

on my lvm setup i noticed that the lvm gets activated _after_ the checkfs skript
is run

therefor i get many error messages when the startup script wants to check my lvm
"partitions"

solution:
the lvm startup in localmount should be place earlier - before the filesystem check

gentoo ROCKS
thanks
Thilo

Anything special needed for LVM startup ?  Like should / be mounted RW, or
is RO ok ?

no, it should be fine

i'll be a little more specific (just to make sure)..
this is in /etc/init.d/localmount

        # LVM support for /usr, /home, /opt ....
        if [ -x /sbin/vgchange -a -f /etc/lvmtab ]
        then
                ebegin "Setting up the Logical Volume Manager"
                #still echo stderr for debugging
                /sbin/vgscan && /sbin/vgchange -a y >/dev/null
                eend $? "Failed to setup the LVM"
        fi

and it works great...
but when you have lvm volumes in you fstab checkfs will try to check them
this fails because the devices have not been created yet, because lvm is not
started up yet...

so the above part should be moved from localmount to the beginning of checkfs

Understood, but since I do not use LVM, im trying to find out if you need
/ mounted RW to start LVM, or if it can be RO .... I want to find out
how far I can take things basically ;)

doh - i did'n catch that / of course means root ;-)

i believe / (root) needs to be RW as vgscan will write to /etc/lvmtab.d/ and
/etc/lvmtab

i don't know what happens if / is still RO

Fixed on CVS, should be in new release of baselayout soon.
