Shrinking a file system can take a long time; it depends on how many files are using space in the part of the file system that needs to be evacuated for the shrink to take place. > It's ~2TB full of data which is mostly rsnapshots of lots of remote > hosts, so lots of little files. Yes, that will take longer. Resize2fs is engineered for safety, which means it copies a lot of blocks, and then it updates the inodes, and then copies more blocks, and then updates the inode involved, etc. So it's a fairly seeky operation that can take a while. Most of the time people are growing their file systems, not shrinking them, so we haven't done a huge amount of optimization for speed in the shrink case.
