...be able to traverse large filesystems (10-350M inodes) backed by spindle-based RAID arrays, I tried several solutions (like intercepting readdir and sorting by inode, playing with cache hints, and such), to no avail. Since I'm mostly facing ext3 and ext4 filesystems, I wrote a tool based on libe2fs which replaces the 'find /' part by directly going to the ext data structures. It has been working great for me for several months, and I've published it at https://github.com/bearstech/e2find There's a data safety issue I'm not quite sure. I'm using libe2fs to open read-...

...btrfsctl -r max /mnt [ Conversion from Ext3 ] This is an offline, in place, conversion program written by Yan Zheng. It has been through basic testing, but should not be trusted with critical data. To build the conversion program, run 'make convert' in the btrfs-progs tree. It depends on libe2fs and acl development libraries. The conversion program uses the copy on write nature of Btrfs to preserve the original Ext3 FS, sharing the data blocks between Btrfs and Ext3 metadata. Btrfs metadata is created inside the free space of the Ext3 filesystem, and it is possible to either make the conv...

Another simple question. How do I calculate the size of the volume from the superblock? Do I just use the two fields: u_int32_t s_blocksize_bits; /* Blocksize for this fs */ u_int32_t s_clustersize_bits; /* Clustersize for this fs */ What is the formula to use? Thanks, John
