We have inherited quite a few mail servers at work with 1 TB + fs. They had 10 of millions of files. When we had a failure and had one reboot it was a nightmare, took ages to fix. Needless to say this is all on a zfs backed nfs filer now thank god I do take your point though in many cases what you say would be a good idea. -----Original Message----- From: owner-freebsd-hackers@freebsd.org [mailto:owner-freebsd-hackers@freebsd.org] On Behalf Of Wojciech Puchar Sent: 09 June 2009 21:10 To: Dan Naumov Cc: Nick Barkas; freebsd-current@freebsd.org; freebsd-hackers@freebsd.org Subject: Re: sysinstall, GJOURNAL and ZFS > filesystems/volumes of today, which can easily span 10tb+ in a > production environment, having to deal with fsck times is a complete > no-go. > just use large block sizes are really small amount of inodes. it's unlikely that you will fill such huge FS with mostly small files, so larger blocks are not wasting space. Just DON'T USE defaults. fsck takes <5 minutes to check 1TB drive with -b 32768 and -i 524288 > One could of course argue that environments where 10tb+ volumes are > used right now are special cases, where the administrator would know No it's not special case. Just needs to be handled properly. _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscribe@freebsd.org"
