[lustre-discuss] FC and sector size over 1024kb

[Рачко Антон Сергеевич]

Hi. I install Lustre on Centos 7.6 server + HP MSA 2040 SAN connected via FC. When I try mount Lustre volume with sector size over 1024 kb, an error occurs (invalid path, etc.).

Two question:

1)    It is possible fix it?

2)    It's safety for data if I remount from sector_size=1024kb to sector_size=16384kb?
