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 VG Name vg_centos6 LV Write Access read/write 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 _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
