Hello All, I am so happy to have found this list and I have searched through the archives looking for an answer to my problem, but have not found it.
I am by no means an expert in LVM and know just enough to set up my disks into a LVM pool and allocate space for different LVs.
I did this almost a year ago now and have been running a very stable linux box with LVM2 with no problems until now. Recently, I was given a couple of old HDDs and tried to add them to my pool using pvcreate/vgextend successfully (at least I think so).
I was able to add the drives to the pool and dole out space to my existing partitions. I thought everything was hunky-dory, but after rebooting, my VG has been corrupted somehow and I can't load any of my LVs.
I didn't have / in the pool (luckily :), but I did place /usr in there and this is the main problem. THe system boots fine up til LVM starting and then I get:
"Couldn't find device with uuid 'blah-blah-blah' "Couldn't find all physical volumes for volume group VolGrp" repeated several times with the same uuid value
for all of my LVs
and finally: "Volume Group "VolGrp" not found"
I can run commands that I have seen other people using to restore stuff in other messages and they seem to exit succssfully such as: # /sbin/vgcfgrestore VolGrp
Restored volume group VolGrp
# /sbin/vgscan
Reading all pysical volumes. This may take a while... Found volume group "VolGrp" using metadatatype lvm2
And if I do some other stuff, I can even get /usr mounted read-only, but this does not survive a reboot.
I know I am missing something, but I can't figure out what. I have been pouring through the mailing lists and google trying to find the solution, but nothing seems to be working.
Any help would be appreciated.
Thanks, ramzy
