Hi Peter,
Thanks for the support.
Everything ran smooth until I did a fsck on the FS on the LV. It's
complaining about a bad superblock
Saying something runs smooth here is somewhat pointless...
Looking at your lvmdump --
pv0 {
id = "8D67bX-xg4s-QRy1-4E8n-XfiR-0C2r-Oi1Blf"
device = "/dev/sdc1" # Hint only
status = ["ALLOCATABLE"]
flags = []
dev_size = 7812456381 # 3.63796 Terabytes
pe_start = 384
pe_count = 953668 # 3.63795
}
This is how your PV was looking when you have created your VG.
Obviously your device /dev/sdc1 had 7812456381 sectors.
(Very strange to have odd number here....)
Later you report # blockdev --getsz /dev/sdc1 as 7812441596
So we MUST start from the moment you tell us what you did to your
system that suddenly your device is 14785 blocks shorter (~8MB) ?
Have you reconfigured your /dev/sdc device?
Is it HW raid5 device ?
Have you repartitioned/resized it (fdisk,gparted) ?
We can't move forward without knowing exact roots of your problem ?
Everything else is pointless waste of time since we will just try to hunt
some random piece of information?
I just hope you have not tried to play directly with your /dev/sdc device
(Since in some emails it seems you try to execute various command directly on
this device)
