pvs can hang if some device has been removed under some circumstances.
Contents
Examples[edit]
pvs (No output if not devices, see pvcreate)
pvs PV VG Fmt Attr PSize PFree /dev/sdb lvm2 --- 50.00g 50.00g
Example output, with one PV create but not assigned to any VG:
pvs PV VG Fmt Attr PSize PFree /dev/mapper/3600508b1001c553702fe495119c850f1p1 VG1 lvm2 a-- <446.60g 32.00m /dev/mapper/3600a09803831416c592b4f566453764t lvm2 --- 250.00g 250.00g /dev/sdc4 VG2 lvm2 a-- <8.28t 100.00g
Output with missing device:
