Hello all:
I have a VMWare virtual CentOS 6 server with the following disk layout:
/dev/sda 15GB
/dev/sdb 100GB
Standard CentOS LVM setup
on sda1
/dev/vg_centos6/lv_root mounted on /
/dev/vg_centos6/lv_swap
on sdb1
/dev/vg_centos6/lv_var mounted on /var
I was starting to run low on disk space for /var, so I shut down the
machine gracefully, extended the disk in VMWare to 250G and rebooted in
single user mode. I then ran the following two commands:
pvresize --setphysicalvolumesize 250G /dev/sdb1
lvresize -L250G /dev/vg_centos6/lv_var
I then rebooted expecting the /var to now be 250G instead of 100G. What
I got was:
No such file or directory trying to open /dev/vg_centos6/lv_var
After dropping to a maintenance shell I could not run any pv* or lv*
commands, always resulting in the error:
File-based locking initialization failed
After Googling forever I found some lv* and pv* commands take
--ignorelockingfailure as a parameter, so now I can "see" the pv and lv
information but I do not know how to recover this partition:
pvdisplay --ignorelockingfailure /dev/sdb1
File-based locking initialization failed
--- Physical volume ---
PV Name /dev/sdb1
VG Name vg_centos6
PV Size 250 GiB / not useable 3.00 MiB
Allocatable yes
PE Size 4.00 MiB
Total PE 63999
Free PE 25599
Allocated PE 38400
lvdisplay --ignorelockingfailure /dev/vg_centos6/lv_var
File-based locking initialization failed
--- Logical volume ---
LV Path /dev/vg_centos6/lv_var
LV Name lv_var

LV Status suspended
# open 0
LV Size 150.00 GiB
Current LE 38400
Segments 1
Allocation inherit
Read ahead sectors auto
- currently set to 256
Block device 253:2
I cannot mount this, I cannot fsck, /dev/mapper/vg_centos6/lv_var does
not even get created. This is a critical server, can anyone please tell
me how to reverse this or at least recover the data?
Thanks!
/Christian
