You don't want that. 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
[OpenIndiana-discuss] ZFS improvements.
Hi, I would like to know if the following improvements are possible on a future openindiana build: 1 - Increase the maximum blocksize. Right now is set at 128k but it should be possible to increase (I would like to try 1MB as my files are usually big). 2 - The compression stops if the compression is not bigger then 12.5% (?). Remove this limitation. If the file compresses, then it should be kept compressed. 3- Add lzma compression to zfs (compression is slower but higher). Following weblink seems to discuss the possibility: http://blogs.sun.com/aalok/entry/serving_up_lzma Open to discussions why the above are good or bad.

Thanks for the good info. What is pretty easy to some has many times turned out to be somewhat difficult for me. Possibly a dimwit on this end but what were the pretty easy search terms you goggled with? Someone not all that familiar with the subject may not come up with good search strings as quick and easy as someone with a better command of the subject. > Note that (newdev) must be a slice.
