I never cared to look for this (does it support ext3, does it work with current kernels, merge status) since offline resizing was always sufficient for me. > A colleague of mine happened to create a ~300gb filesystem and started > to migrate Mailboxes (Maildir-style format = many small files (1-3kb)) > to the new LUN. At about 70% the filesystem ran out of inodes; Well - easy to fix, newfs again with proper inode density (perhaps 1 per 2 kB) and redo the migration. Of course you're free to pay for a new file system if your fellow admin can't be bothered to remember newfs's -i option. > > Well, such "silly limitations"... looks like they are mostly hot air > > spewn by marketroids that need to justify people spending money on their > > new filesystem. > > Have you ever seen VxFS or WAFL in action? No I haven't. As long as they are commercial, it's not likely that I will. > Great to see that Sun ships a state-of-the-art Filesystem with > Solaris... I think linux should do the same... I think reallocating inodes for UFS and/or ext2/ext3 is possible, even online, but someone needs to write, debug and field-test the code to do that - possibly based on Andreas Dilger's earlier ext2 online resizing work. -- Matthias Andree
