When using ext2file=exportname to pick the file to server from the client's export name, we do not want to leak the underlying plugin's export list. While touching this, take advantage of string lifetimes via nbdkit_strdup_intern and similar for less cleanup bookkeeping. Note that we don't actually i...

Not enabled by default, because of the potential security concern that a client can use this to sniff what file names exist in the image; but for an opt-in setting in the server, this lets a single nbdkit process serve multiple files from an ext2 image (one at a time, unless we find a way to allow a filter to open the plugin once without a current connection, then share that opened plugin across multiple client connections). In testing this manually, I learned that qemu 4.0 fails to preserve leading / in nbd://host:port//path/to/file (no m...

There is a small test provided. I tested this a lot more locally and it seems pretty robust. Rich.

I often get the message: EXT2-fs warning (device hda6): ext2_fill_super: mounting ext3 filesystem as ext2 I have googled for a reason and a way to solve this - but not found something I could use. Maybe somebody here konws what to do? best regards keld

Hope someone can point me in the right direction. I don't know if what I am trying to do should work or not. I have 2 disk images. One is a VM with an ext2 boot filesystem and ext4 filesystems with the OS loaded. I am amble to guestmount this with no issue and am able to see the files that are on the ext2 file system. I can also run guestfish on the image, mount the ext2 filesystem, and list the files. However, the second image I have is only a boo...

Hello Gurus, Greetings. I have been assigned some work on the development of a migration tool. The requirement is that it has to migrate the data on a UFS/VxFs filesystem to an ext2 filesystem. What are the technical apects I will have to look into to achieve the same? Is it possible to change the on-disk structure of the UFS/VxFs filesystem to an ext2 filesystem? The question may sound weird but then that is the requirement. Kindly help me. Kindly send a cc of your mail...
