vgextend fail on Couldn't create temporary archive name

Question

we add anew virtual disk as sdb ( from the vcenter ) in order to increase the /var partition

we have redhat version 7.5

so after we add the disk we get

 pvs
  PV         VG   Fmt  Attr PSize   PFree
  /dev/sda2  vg00 lvm2 a--  <39.51g 60.00m
  /dev/sdb        lvm2 ---   80.00g 80.00g

now we initialize a disk or partition

pvcreate /dev/sdb

now we want to add this to volume group vg00

vgextend vg00 /dev/sdb
  Couldn't create temporary archive name.

why we get " Couldn't create temporary archive name. "

Solution

why we get " Couldn't create temporary archive name. "

Most likely because your root partition is full.

Try clearing out some files in the root (/) partition before running vgextend.
