Hi,
Re-sending because I'm not sure this ever made it out to the list.
Hoping someone can give me some advise here.
So I managed to recover my raid, now I have what I think is a complete
md0 and md1. However when I pvscan I get different results depending on
whether md0 is online or not.
Here is an example of what I'm referring to:
# pvscan
Warning: Volume Group raid is not consistent
PV /dev/md0 VG raid lvm2 [1.82 TB / 1.82 TB free]
Total: 1 [1.82 TB] / in use: 1 [1.82 TB] / in no VG: 0 [0 ]
that is what I get when I have md0 and m1 enabled. However if I disable md0:
# mdadm -S /dev/md0
mdadm: stopped /dev/md0
# pvscan
Couldn't find device with uuid 'oI1oXp-NOSk-BJn0-ncEN-HaZr-NwSn-P9De9b'.
Couldn't find device with uuid 'oI1oXp-NOSk-BJn0-ncEN-HaZr-NwSn-P9De9b'.
PV unknown device VG raid lvm2 [1.82 TB / 0 free]
PV /dev/md1 VG raid lvm2 [1.36 TB / 0 free]
Total: 2 [3.18 TB] / in use: 2 [3.18 TB] / in no VG: 0 [0 ]
So that said md0 exists (temporarily ) across 3 USB mass storage
devices. After the initial rebuild I suspected that the device order was
mixed up (yeay for random USB device assignments). I verified that this
was in fact the case with the first and last 64k of the array containing
no PV label and the middle one containing the label. I've since
corrected it so the disks are (should be) in the right order again. So I
guess what I'm asking is what I should do next here, my experience with
LVM is limited. Am I hosed here? Is my data recoverable?
