I have a PV allocated, that is larger than the actual volume it resides on.
Somehow, and I've not been able to ascertain how, when fdisk was run, on
a new RAID array it produced the following partition size:
fdisk -l -u /dev/sda
Disk /dev/sda: 1499.9 GB, 1499999502336 bytes
255 heads, 63 sectors/track, 182364 cylinders, total 2929686528 sectors
Units = sectors of 1 * 512 = 512 bytes
Disk identifier: 0x0003d809
Device Boot Start End Blocks Id System
/dev/sda1 63 2930304194 1465152066 8e Linux LVM
The complete /dev/sda1 was then allocated to a PV.
Later, at boot time, I noticed warnings about the partition allocation
being larger than the actual disk, which led me to investigate what was
wrong. After correcting this, fisk now reports the correct size for the
partition:
fdisk -l -u /dev/sda
Disk /dev/sda: 1499.9 GB, 1499999502336 bytes
255 heads, 63 sectors/track, 182364 cylinders, total 2929686528 sectors
Units = sectors of 1 * 512 = 512 bytes
Disk identifier: 0x0003d809
Device Boot Start End Blocks Id System
/dev/sda1 63 2929677659 1464838798+ 8e Linux LVM
However, the PV allocations are still based on the "incorrect" partition
sizing, and hence, they are also incorrect:
pvdisplay
--- Physical volume ---
PV Name /dev/sda1
VG Name raid_vg
PV Size 1.36 TB / not usable 2.97 MB
Allocatable yes
PE Size (KByte) 4096
Total PE 357627
Free PE 76027
Allocated PE 281600
PV UUID OOBb0e-8fyt-mhfr-Oshw-mS8d-Mcay-t2ixBb
This shows a "Total PE" of 357627, which according to my maths, comes
out to 1,464,840,102 Blocks, or 2,929,680,384 Sectors, on the device.
This is larger that the actual disk.
How can I correct the PV allocations, so that they reflect the actual
device, not the "incorrect" sizes, that were present when PVCREATE was
originally run.
Cheers,
Eddie
