The number of free inodes is a made up number. ;) That's for normal usage. Well, David don't forget what you tell me some time ago about xfs_repair In terms of inode count, I generally use the rule that for every 10million inodes you need a gigabyte of RAM for repair - you needed about 500MB for 6million inodes. The inode count also affects xfsdump/xfsrestore operations but I don't know the details. There was a huge improvement in performances for partial dump with xfsprogs-2.8.16 IIRC. Regards, Daniele P.
