Linux üzerinde tek bir vdev olan 2.6.32-431.11.2.el6.x86_64 çekirdeğinin altında bir ZFS zpool var. Vdev bir SAN cihazıdır. Ben SAN boyutunu genişletti ve zpool rağmen sahip autoexpand
olarak ayarlanmış on
bile / ihracat, makinanın yeniden havuza ithal ve kullandıktan sonra, zpool online -e
ben havuz genişletmek için alamadı. Vdev'in daha büyük olduğundan eminim çünkü fdisk
215GiB'den 250 GiB'ye yükseldiğini gösteriyor. İşte yaptığımın bir örneği:

Bu zpool'ı nasıl genişletebilirim?
zpool online -e pool vdb
hile yapan komuttur. Şimdi bir dizi libvirt sunucusunda Linux üzerinde ZFS kullanıyorum ve bu benim için çalışıyor (partprobe olmadan)
