I patched ltfs so that all the max sizes (256kB and 512kB for Linux) are set to 64kB for NetBSD. I can now format and mount the LTFS filesystem, but I need to limit the block size to under 64kB. This will work: dump -0f - / | dd obs=63k of=/ltfs/dump20181227 This hangs the filesystem: dump -0f - / | dd obs=64k of=/ltfs/dump20181227 I tested on glusterfs that our FUSE implementation does not limit writes to 64k chunks, hence I assume I introduced a bug in ltfs with the 64kB limit everywhere. Is there a reason other than historical for NetBSD 64kB limit? -- Emmanuel Dreyfus [email protected]
