If it turns out you don't like ext3, you can even go back to ext2 by unmounting the ext3 fs and remounting it ext2. Going to reiserfs will require a reformat of your partition, because the format is completely different. regards, Rik -- Virtual memory is like a game you can't win; However, without VM there's truly nothing to loose... http://www.surriel.com/ http://www.conectiva.com/ http://distro.conectiva.com.br/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
Re: reiserfs patch for 2.4.0-final
Is ext2 upgradable to reiserfs or ext3? If so, is it transparent..or like a umount, convert, mount..or do you like have to import to a whole new partition? Pointers to any docs of this sort would work for an answer Thanx, -Tony .-._.-._.-._.-._.-._.-._.-._.-._.-._.-._.-._.-._.-._.-._.-._.-._.-._.-. Anthony J.

The first optimization is tuning for reiserfs_get_block, I think writepage clustering will be easier (and more beneficial) if we work out the buffer.c changes I've been posting. I also want to change the log block allocation a bit, so the log blocks are allocated as the transaction progresses, instead of all at the end. I think that will make us much more VM friendly, and let me get rid of the inode writing kludges. It'll be a busy weekend ;-) -chris - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/

Since 2.4.0 final should fix a few i/o performance issues (particuarly under heavy write loads), a quick few ext2 vs. reiserfs benchmarks would make very interesting reading ;-) Cheers Chris - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
