OpenIndiana is a distribution, not a kernel development group. For that you have to bug Illumos team. > 1 - Increase the maximum blocksize.

Read/modify/write overhead would be huge. 128KB is big enough to provide good random access without wasting too much space or having a big overhead. > 2 - The compression stops if the compression is not bigger then 12.5% (?). > Remove this limitation.

I think it is only a single line change. > 3- Add lzma compression to zfs (compression is slower but higher). Following > weblink seems to discuss the possibility: New compressions would be interesting. But I am very worried about ZFS fragmentation. If Illumos ZFS can not interoperate with Oracle ZFS or FreeBSD ZFS, we will alienate the FS and the comunity. I would like to be able to boot from a dataset compressed in GZIP. That would be a "simple" GRUB change. Anyway, the right people to request this is Illumos, not OpenIndiana. - -- Jesus Cea Avion _/_/ _/_/_/ _/_/_/ j...@jcea.es - http://www.jcea.es/ _/_/ _/_/ _/_/ _/_/ _/_/ jabber / xmpp:j...@jabber.org _/_/ _/_/ _/_/_/_/_/ . _/_/ _/_/ _/_/ _/_/ _/_/ "Things are not so easy" _/_/ _/_/ _/_/ _/_/ _/_/ _/_/ "My name is Dump, Core Dump" _/_/_/ _/_/_/ _/_/ _/_/ "El amor es poner tu felicidad en la felicidad de otro" - Leibniz -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQCVAwUBTOszCJlgi5GaxT1NAQJqSgQAgec4r37bSSH5ZGimAbOOzz7wkGTVCXWR XNb4o+XqNm+/wDSzDGb4zien6k7xfeU2eUi1ZlPVVUS/9AJAms5Nor8ubxkF6Tv/ DlE5HCYZGNkOCFdTX8kcwCs1WOktnvb6jUvuwPqw5uT0aDDbh16F6YT8NR+mX9Yn u37MNUkOt8s= =YM65 -----END PGP SIGNATURE----- _______________________________________________ OpenIndiana-discuss mailing list OpenIndiana-discuss@openindiana.org http://openindiana.org/mailman/listinfo/openindiana-discuss
