I've been slowly converting my small corner of the world to JFS over the last couple of months as I noticed significant gains (over ext3 and xfs) in multi-user performance but something lept out at me for the firrst time last night as I converted the root filesystem of one machine:
ext3 pre conversion: Filesystem Size Used Avail Use% Mounted on /dev/md0 15G 8.1G 6.0G 58% /mnt/gentoo i then tarred everything up, reformatted to JFS with 'mkfs.jfs /dev/md0' and then untarred: Filesystem Size Used Avail Use% Mounted on /dev/md0 15G 8.1G 6.9G 55% /mnt/gentoo Used space is the same, but the jfs formatted _says_ there is ~900mb more free. I'm curious as to the reason, as this might be another point for me to accelerate conversion. thanks dave _______________________________________________ Jfs-discussion mailing list [email protected] http://www-124.ibm.com/developerworks/oss/mailman/listinfo/jfs-discussion
