/dev/md3 is a raid5 array consisting of 4*500Gb disks
pvs and pvscan both display good info:
% pvscan | grep /dev/md3 PV /dev/md3 VG RaidDisk lvm2 [1.36 TB / 0 free]
% pvs /dev/md3 PV VG Fmt Attr PSize PFree /dev/md3 RaidDisk lvm2 a- 1.36T 0
But pvdisplay... % pvdisplay /dev/md3 --- Physical volume --- PV Name /dev/md3 VG Name RaidDisk PV Size 1024.00 GB / not usable 8192.00 EB Allocatable yes (but full) PE Size (KByte) 4096 Total PE 357702 Free PE 0 Allocated PE 357702 PV UUID tXGBfv-mfhF-FEXV-hjOG-saIz-iAhA-vZ62DW
The "PV Size" line is very odd, indeed!
My other lvm disk (/dev/md4) looks just fine: % pvdisplay /dev/md4 --- Physical volume --- PV Name /dev/md4 VG Name Mirror PV Size 267.36 GB / not usable 3.50 MB Allocatable yes PE Size (KByte) 4096 Total PE 68444 Free PE 4352 Allocated PE 64092 PV UUID Bav2oP-nlZB-f6H3-XBow-iIde-AqKI-a0JyYk
Any ideas on why "PV Size" looks so broken on md3 ?
