[linux-lvm] funny PV action

[linux-lvm] funny PV action

[Christoph Resch]

Hi all,

may someone kindly assist me in thei quite funny behavior of LVM

i work on a runnging LVM system .. everything works as it should BUT:

when running pvscan i get 

root@prime:~# pvscan
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- inactive PV "/dev/md1" of VG "system"   [19.97 GB / 0 free]
pvscan -- ACTIVE   PV "/dev/md2" of VG "dataraid" [13.88 GB / 0 free]
pvscan -- ACTIVE   PV "/dev/md3" of VG "dataraid" [68.36 GB / 0 free]
pvscan -- total: 3 [102.24 GB] / in use: 3 [102.24 GB] / in no VG: 0 [0]

# well /dev/md1 is my system ( / , /usr, /var ,... ) it works quite fine :-o

root@prime:~# vgscan
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- found active volume group "system"
vgscan -- found active volume group "dataraid"
vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created
vgscan -- WARNING: This program does not do a VGDA backup of your volume 
groups

# well thats great ;-) 


root@tttprime:~# lvscan
lvscan -- ACTIVE            "/dev/dataraid/ttchip" [9 GB]
lvscan -- ACTIVE            "/dev/dataraid/private" [20 GB]
lvscan -- ACTIVE            "/dev/dataraid/tttech" [20 GB]
lvscan -- ACTIVE            "/dev/dataraid/projects" [17 GB]
lvscan -- ACTIVE            "/dev/dataraid/sandbox" [9 GB]
lvscan -- ACTIVE            "/dev/dataraid/marketing+pr" [7.23 GB]
Segmentation fault

# oops i miss al my systemLVs .. still running on it ;-( 

root@tttprime:~# cat /proc/mounts
rootfs / rootfs rw 0 0
/dev/root.old /initrd ext2 rw 0 0
/dev/root / ext3 rw 0 0
proc /proc proc rw 0 0

/dev/dataraid/projects /ttt/tttech/projects xfs rw 0 0
/dev/dataraid/sandbox /ttt/tttech/projects/sandbox xfs rw 0 0

still everything runs .. but i want it to be clean .. any advice would help 

thanks and best regards

Hi Jord,

i can see the same behavior on my LVM-Installation, though i dont dual-boot. i 
get this strange situation after preparing for disaster-recovery with 
mondo-rescue .. since then my first PV is always inactive, but i can boot 
from it and work normally ... 

did you found something ? .. maybe a lvm-version problem -- on debian i use 
lvm-common	1.5.9.3
lvm10 		1.0.7-8

thanks for reply

ok .. according to the 'devfs'-issue i found out to not have a identical /dev 
on the initrd and on the system 

after sync it all works perfectly again :-) 

thanks anyway

To get around the devfs/no devfs problem I went with EVMS and
device-mapper in Gentoo (with devfs), and its been running sweet ever
since. EVMS runs in LVM compatibility mode, so I can work with the LVs
in both RedHat and Gentoo.
