Now this is interesting. I noticed that when I dumped the config, and
look at it, one of the (largest) pv's isn't showing up at all. I also
don't see a way to for vgcfgbackup to pull from a specific physical
device, so not sure how I can 'force' it to see the other lvm
partition. This is what I have now, but partition /dev/hdb1 is not
showing up. These are 2 partitions I used to move extents from failing
to disk before it completely died. I'm guessing this is why it doesn't
see the rest of the VG, very little right now isn't listed as "missing"
even those /dev/hdb1 is there, but vgscan doesn't seem to see it.
pv0 {
id = "YnfiRa-QnzV-Llio-quX6-UrHQ-WuCl-RiwZWd"
device = "/dev/hda7" # Hint only
status = ["ALLOCATABLE"]
pe_start = 8576
pe_count = 373 # 1.45703 Gigabytes
}
pv1 {
id = "qFNI3x-yIgQ-Lqco-PDNN-djJ4-UiWw-szmJiW"
device = "/dev/hda8" # Hint only
status = ["ALLOCATABLE"]
pe_start = 8576
pe_count = 444 # 1.73438 Gigabytes
}
Thanks again for all the help...definitely won't be using this across
disks not on RAID anymore...
