I'm testing LVM on a redhat EL 5 with the following configuration :
* one FSC Primergy server with one dual port Qlogic HBA 2462
* each Qlogic port is connected to a SAN (dual fabric)
* use of device mapper
* use of LVM to define a mirror disk on two IBM ESS 2105 disks
Everything was fine and worked. I have created the lvm with :
root linprd11 by-id]# lvcreate -L 10G -m1 -n mirror1vg1
vg1 /dev/mapper/1IBM_2105_41630194 /dev/mapper/1IBM_2105_41630317
Logical volume "mirror1vg1" created
Sync between the two mirrors was ok :
[root linprd11 by-id]# lvs
LV VG Attr LSize Origin Snap% Move Log Copy%
mirror1vg1 vg1 mwi-a- 10.00G mirror1vg1_mlog 100.00
Then, I suppress access to one image of the mirror and reboot the Linux server. The boot failed and give the following error message :
* An error occurred during the file system check. Dropping you to a shell - Give root password for maintenance :
When I try the command lvm -a -o +devices -P , I receive Locking type 1 initialisation failed. If I use the --ignorelockingfailure, I receive :
Can you tell me how I can solve this problem ?
Thanks a lot for your help.
