Stratis seems to create all filesystems with a size of 1TB, and extends them as needed from there. However that means that a filesystem could potentially be expanded many times, which, as I understand it, is very suboptimal or worse, can lead to problems (inode allocation, AGs count and structure, etc). --=20 ------------------------------------------------------------------------ Emmanuel Florac | Direction technique | Intellique | | +33 1 78 94 84 02 ------------------------------------------------------------------------ --Sig_/B/RfdDx=hC/.o+MuEojJmos Content-Type: application/pgp-signature Content-Description: Signature digitale OpenPGP -----BEGIN PGP SIGNATURE----- iEYEARECAAYFAluzgpMACgkQX3jQXNUicVYB1wCgpwLePuzHwZhMkTLBZ9pEnmiT FMcAoPwszFIz+zZUjs3ekcPzUEOzhJD0 =UgnB -----END PGP SIGNATURE----- --Sig_/B/RfdDx=hC/.o+MuEojJmos--
